These organisms are rarely recovered by culture from FecalSwab samples after 24 h of storage (7, 14), but in the presence of unfavorable environmental conditions, C. jejuni can enter a viable but nonculturable state (15). Several studies have demonstrated rectal swabs to have equivalent or greater sensitivity relative to bulk stool in the molecular detection of viral, bacterial, and parasitic enteric pathogens (3, 4, 17,19). Remel Cary Blair Transport Medium is a semisolid medium recommended for use in the transportation and preservation of clinical specimens, primarily stool and rectal swabs. hmo6>6Q|P!bF>K`;ww")JD]#y2 The preapproval for your request will . describe 3 phyla used to classify human parasites. Specimens that need to be transported at a colder temperature can also be accommodated. In contrast, bulk stool predominately consists of contents derived from the small intestine resulting in a pathogen-diluting effect of the sample. Be aware of the dangers associated with biological, chemical, and physical hazards, and take these precautions to avoid contact with the specimen. Nonetheless, these findings suggest that using 50l of FecalSwab specimen may provide improved enteropathogen detection in comparison to bulk stool in specimens yielding lower pathogen concentrations. Urine Transport Tube (Yellow topped tube) Containsl transport media to stabilize urine samples for urinanalysis only. Despite having included some of the most common causes of acute diarrhea, we did not cover all pathogens that would be of clinical importance to isolate from FecalSwab specimens. We have no other funding or conflicts of interest to disclose. These tubes may not be used for urine culture testing. Secure the lid and mix specimen well by hand shaking the vial. DPDx is an educational resource designed for health professionals and laboratory scientists. 2017. The By following these simple guidelines, you can ensure that your samples arrive safely and on time at their destination. Ocular: corneal scrapings, tissue, washings. 2018. Effect of FecalSwab storage time and temperature on the molecular detection of viral and bacterial enteropathogens in stool specimens. 2014. such as blood, urine, stool, tissue and fluid. (9) enhance our findings, as the authors evaluated the compatibility of the FecalSwab with additional pathogens (Yersinia enterocolitica, enterotoxigenic Escherichia coli, Vibrio spp., and Plesiomonas shigelloides) using the BD Max extended EBP panels; however, there are still several pathogens, especially intestinal parasites, that require investigation. Each test request (order) requires preapproval by the CDC Parasitic Diseases Branch. One important consideration when evaluating the implementation of a collection device is the stability of the specimen in context of its use. Specimen and shipment details per test, as well as points of contact, can be found in the appropriate link below. Stool specimens for the EVP assay in the laboratory are generally submitted as an unpreserved specimen. As our findings demonstrate the FecalSwab to be a suitable collection device for the BD Max EVP and EBP assays, it was of further interest to evaluate the effect of transport and storage of stool specimens on molecular diagnostic results. Astrovirus was the only viral target found to have a significant change in molecular detection, which was only observed at 35C (CT 1 at days 7 and 14). Standard of care recommends 5l of unpreserved stool for the EVP assay and 10l of specimen preserved in Cary-Blair for the EBP assay. There are several potential hazards associated with transporting blood and specimens. They should be transported at temperatures between 20C and 35C. As the superior sensitivity of the FecalSwab was not target specific, we attributed these observations to variations in stool viscosity, leading to subtle variations in swab collection volume from each specimen. In several cases, multiple pathogens were detected by both collection methods, with 8 samples having two and 1 sample having three pathogens. Dropoff is a same-day courier service that has been providing businesses nationwide with 24/7 logistics support since 2014. mid-stream urine. Specimen Preparation for Transportation 1. Therefore, these findings emphasize the importance of identifying a FecalSwab sample testing volume that preserves assay sensitivity for various stool consistencies without overloading or underloading the assay. The performance of the FecalSwab inoculation compared to bulk stool for each target is summarized in Table 1. 2019. The fresh stool specimen must be received within 1-2 hours of passage. If you cannot transport the specimen to the lab within two hours, follow specimen handling requirements marked below: Clostridium DifficileRefrigerate specimen and submit within 24 hours. Analysis for this study was performed using GraphPad Prism version 7.04 (San Diego, CA, USA). HHS Vulnerability Disclosure, Help Single primary containers shall not contain more than 1000 ml; however, two or more primary containers, whose combined volume does not exceed 1000 ml can be placed in a single secondary container. As stool specimens are often collected off-site from the clinical microbiology laboratory and require transport, we assessed the stability of stool specimens stored for up to 14days at 4C, 22C, or 35C to account for varying transportation conditions. 2. lice.

Baseline mean CT values for the majority of enteropathogens ranged from 24 to 27 with the exception of Salmonella (CT = 30.1), rotavirus (CT = 10.9), astrovirus (CT = 15.5), and adenovirus (CT = 9.2). endstream endobj 725 0 obj <>/Metadata 114 0 R/PageLayout/OneColumn/Pages 720 0 R/StructTreeRoot 132 0 R/Type/Catalog>> endobj 726 0 obj <>/Font<>>>/Rotate 0/StructParents 0/Type/Page>> endobj 727 0 obj <>stream FOIA To validate the FecalSwab for use with the BD Max EVP and EBP assays, we compared the performance of 186 matched FecalSwab-bulk stool specimens in a clinical setting. In FecalSwab samples stored at room temperature, the number of CT required to detect Salmonella was significantly higher at 24 h (CT, 2.20.7) and at 48 h (CT, 3.00.3) than baseline; however, at days 7 and 14, detection significantly improved (CT of approximately 11.0). In order to maintain this temperature, the samples must be packed in an insulated container with a cold pack. Do not send the entire stool collection. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. For example, an inverse correlation between the relative abundance of the bacterial genus Blautia in stool samples and the effect of that sample on human astrovirus viability has previously been observed (12). CLEAN AND LEAKPROOF - Each specimen cup comes with a tight sealed screw on cover, keeping your specimen secure and protected during transportation. This work was additionally supported by the McMaster University Daniele Triva Memorial Post-Doctoral Award in Diagnostic Clinical Microbiology (M.R.-G.). Lastly, the current study focuses on the performance of the FecalSwab in its compatibility with the BD Max system. Role of environmental survival in transmission of Campylobacter jejuni, Pathobiology of Salmonella, intestinal microbiota, and the host innate immune response. Therefore, we followed the specimen preparation pathway for unpreserved specimens according to the BD Max package insert, which includes directly inoculating the sample buffer tube with 5l of stool. If you are transporting blood or other specimens across state lines, it is important to be aware of any additional regulations that may apply. Clinical evaluation of the FecalSwab as a specimen type for the BD Max enteric viral and enteric bacterial panels. Write patient name legibly on specimen container. Collect a small amount of stool by inserting a sterile cotton-or polyester-tipped swab into the stool and rotating it. It contains detailed instructions on requisitions, irreplaceable sample handling, collection procedures, infectious substances, and more. By demonstrating equivalent performance to matched bulk stool and maintaining molecular detection sensitivity when stored at 4C, we suggest that the FecalSwab is a suitable specimen type for enteropathogen diagnostics on the BD Max system. Cannon JL, Baker M, Barclay L, Vinje J. 2019. This usually requires a water-to-feces ratio of one-to-one. However, diarrheal disease remains a major cause of morbidity and mortality worldwide (1). Room Temperature (15-25 C) 1. In this study, we evaluated the FecalSwab as a specimen type for the BD Max system using the viral and bacterial enteric panels (BD Diagnostics, Baltimore, MD, USA). However, please note that it can take the TUGs considerable time to complete their transport route. M.S. Kabayiza JC, Andersson ME, Welinder-Olsson C, Bergstrom T, Muhirwa G, Lindh M. For example, whole blood needs to be transported at a cool temperature in order to maintain its viability, while urine can be transported at room temperature. For an overview including prevention, control, and treatment visit www.cdc.gov/parasites/. The patient should be asked to deliver the specimen to the clinic immediately after collection. It is important to read the transportation instructions for each type of sample to ensure that it is handled correctly. has previously received research support from Copan Italia. When transporting blood samples, it is important to keep them cool but not frozen. Substances like charcoal digestion marker, castor oil, and mineral oil should be excluded from the diet prior to and during the collection. Comparison in molecular detection (CT values) between bulk stool and 10-l FecalSwab inoculums for each pathogen target were significant (**, P<0.01). Criteria for stool selection included prior reverse transcriptase PCR (RT-PCR) CT values of 15 to 30 and sufficient volume (7ml) to perform volume optimization studies. Interestingly, despite being a fastidious microaerophile, Campylobacter jejuni was the bacterial target least affected by changes in FecalSwab storage conditions. Specimens for culture should not be refrigerated or exposed to extreme cold, excessive heat, or sunlight.

Enteropathogen detection in children with diarrhoea, or vomiting, or both, comparing rectal flocked swabs with stool specimens: an outpatient cohort study. As the FecalSwab contains a diluted specimen, we determined equivalent loading amounts to match bulk stool inoculation (standard of care) for the EBP and EVP assays. Do not mix urine or water with the specimen. 724 0 obj <> endobj McNemars test for paired samples was used to assess FecalSwab versus bulk stool detection for each target pathogen. This paperwork will include information on the medical samples being transported, as well as your contact information. In all cases, we observed the sensitivity of the FecalSwab collection method to be 100% when results were compared with previous clinical reporting for the specimen by the laboratory. A total of 10l of preserved bulk stool was used to inoculate the EBP sample buffer tube as described by the package insert. Clearly label your sample with all the necessary information. Several studies have provided evidence of multiple mechanisms employed by Salmonella that enable the organism to outgrow members of the microbiota under the inflammatory conditions induced by the innate immunity (16). For example, increased viscosity likely resulted in excess stool picked up by the FecalSwab, thereby increasing sensitivity of the collection method. PMC legacy view Goneau LW, Mazzulli A, Trimi X, Cabrera A, Lo P, Mazzulli T. Another limitation of our study is due to the probability that our findings may not be generalizable to all stool specimens, as we did not evaluate the role of host (microbiota, immune status, and antimicrobial treatment) and pathogen (pathogenicity, metabolism, etc.) Few published studies have evaluated the effect of time and temperature on the molecular detection of viral enteropathogens in clinical specimens; however, a study quantifying loss of norovirus RNA RT-PCR positivity in clinical stool samples did not observe a significant change in molecular detection over 7years of storage at refrigeration temperatures (10). Rectal swabs can be used for diagnosis of viral gastroenteritis with a multiple real-time PCR assay. Specimen should be stored refrigerated during the collection. As we did not observe any loss in sensitivity for the FecalSwab as part of the clinical evaluation, we concluded 50l of FecalSwab transport medium (Cary-Blair) to be the optimal sample volume for the BD Max EVP and EBP assays. The package should be able to withstand rough handling and passage through routinely used sorters, conveyer belts, etc. BD Max EVP and EBP sample buffer tubes were inoculated with 10 or 50l of FecalSwab specimen prepared from a positive clinical specimen and run in triplicate for each molecular target. The FecalSwab system (Copan Italia, Brescia, Italy) incorporates a flocked swab in a compact liquid-based system (2ml of modified Cary-Blair medium), providing a convenient alternative to preserved bulk stool for both culture and molecular-based diagnostics. 761 0 obj <>stream 2. 2017. Tenets of . With increasing consolidation of microbiology laboratories and the requirement to perform testing off-site in centralized laboratories, there was a need to evaluate the utility of the FecalSwab for the transport and storage of stool specimens under various temperatures. 2013. When working with medical couriers, you dont need to worry about these requirements because the carrier will be expertly aware of all the requirements necessary for proper delivery.

We built our system to help you schedule, track and manage all your same-day deliveries in one place. these vectors are often ectoparasites. However, this is the first report evaluating the FecalSwab with the BD Max system EVP assay. In conclusion, our findings suggest that the Copan FecalSwab is a suitable collection device for both viral and bacterial enteric pathogens on the BD Max system. Place the specimen cup (s) inside the plastic biohazard . Preparation of the FecalSwab specimen was performed according to the Copan package insert. DPDx is an educational resource designed for health professionals and laboratory scientists. Consequently, each unpreserved stool specimen was prepared using two separate methods as follows: bulk stool as per the BD Max EVP and EBP protocols and the FecalSwab method. Although our findings and those from others suggest that the FecalSwab can be used for enteric diagnostics with a range of platforms (6, 8, 9), volume standardization and clinical evaluation is required for laboratories using other nucleic acid amplification systems. Note: When you ship a specimen to CDC, make sure your package will arrive on a weekday and will not arrive at CDC on the weekend or a federal holiday. a. These approved containers of less than 500 grams per container are acceptable for transport and can be submitted without further manipulation by the receiving laboratory. In contrast to other enteric pathogens included in our stability studies, we observed the molecular detection of Salmonella to improve over time with increasing temperatures. name 3 parasitic vectors. We determined the sensitivity of each collection method according to previous stool characterization of target positivity from the clinical laboratory (Table 1). The FecalSwab is a more dilute specimen than bulk stool samples; therefore, we first optimized the volume of FecalSwab medium required for equivalent detection in the BD Max EVP and EBP assays. It would be of interest to further investigate whether decreased astrovirus stability at elevated temperatures can be replicated in other stool specimens and if stability is associated with certain bacterial populations. Instruct the patient to collect the stool specimen on a piece of toilet tissue or old newspaper and to transfer it to the container, using the two sticks. Discuss the test and the procedure with the patient. As a solution, rectal swabs have been proposed as an alternative to bulk stool collection for the detection of enteric pathogens (3,5). Medical sample transport is a critical part of the medical process. Impact of long-term storage of clinical samples collected from 1996 to 2017 on RT-PCR detection of norovirus, Environmental persistence and transfer of enteric viruses. Specimen is plated . CDC twenty four seven. Secure the lid or cap on the container. Store at 2-8 o C. Using a graduated cylinder, add sufficient water to reach milkshake consistency. Collect the specimen during the early phase of the disease and as far as possible before the administration of antimicrobial agents. Transport of specimens weighing more than 500 grams per container is unacceptable. All specimen containers must be transported in a double-sided, self-sealing polythene bag with one compartment containing the laboratory request form and the other the specimen. However, the FecalSwab system is only FDA approved for the transport and culture of enteric bacterial pathogens, and it has not been well evaluated for its suitability with molecular diagnostic platforms. Therefore, 50l of FecalSwab medium was used to perform a clinical evaluation of the FecalSwab protocol and the molecular detection stability studies. and transmitted securely. All specimens must be placed into a primary container labeled with at least two patient identifiers. Transfer the entire collection to a blending container. This provides guidance on how to collect a fecal specimen and transfer to transport medium for diagnosis ofacute bacterial diarrheal disease.

Read some tips on how to choose a logistics partner for your needs. In the current study, we evaluated the Copan FecalSwab as a collection/transport device for the molecular detection of viral and bacterial enteropathogens using the BD Max system. sharing sensitive information, make sure youre on a federal 1. mosquitoes. The rules for the shipment of preserved specimens are the same as those for unpreserved specimens except that they do not need refrigeration. The FecalSwab system represents an alternative method for collecting and transporting stool and rectal swab specimens for enteropathogen detection. Evaluation of the FecalSwab system for the transport and storage of stool specimens for viral and bacterial molecular diagnostics. government site. If you must come into contact with the specimen, make sure to wash your hands thoroughly afterward. Don't pee on your stool or in the collection hat. In addition, overall sensitivity for each enteric assay was calculated using the total number of targets detected for the EVP and EBP as the reference for each collection method. Nonetheless, the FecalSwab system represents a valuable tool that pairs the ability to culture enteric bacteria for susceptibility testing (7, 14, 20) and serotyping with molecular diagnostics using the BD Max system. Collectively, these panels provide broad coverage of key bacterial (Salmonella spp., Shigella spp./enteroinvasive Escherichia coli [EIEC], Campylobacter spp., and Shiga toxin-producing organisms such as Shiga toxin-producing E. coli [STEC] and Shigella dysenteriae) and enteric viral pathogens (norovirus, rotavirus, adenovirus, sapovirus, and astrovirus). Based on these criteria, FecalSwab samples stored at 4C did not demonstrate any significant change in molecular detection (mean CT 1) with the exception of Salmonella, which was detected 2 CT later than baseline when measured at days 7 and 14. Stool Specimen Collection. . Its important to consult with a medical transportation professional before attempting to transport specimens at this temperature. 1-2 gm quantity is sufficient. Silbert S, Gostnell A, Kubasek C, Widen R. Order the following test when aliquot is prepared in the receiving laboratory prior to transport to ARUP: Record the total weight of the collection, the amount of water added, and the length of the collection period in both the test order and on the aliquot container. Evaluating the preservation and isolation of stool pathogens using the COPAN FecalSwab transport system and walk-away specimen processor. Use ARUP supply #040910, unpreserved stool vial. Do not pass the specimen directly into the toilet or directly into the collection vial. Copan FecalSwab collection devices have previously demonstrated equivalent performance to bulk stool for enteric pathogen detection using culture methods (7) and with the Cepheid Xpert (6), BioFire FilmArray (8) and BD Max (9) molecular platforms. Microbiology Specimen Collection for specific instructions. Specimens positive for sapovirus (n=21) and astrovirus (n=21) were previously characterized using laboratory-developed multiplex PCR methods and biobanked at 80C prior to being shipped to St. Josephs Healthcare Hamilton for further processing. If possible, submit more than one specimen on different days. Stool should be submitted in 10% Formalin. These cookies perform functions like remembering presentation options or choices and, in some cases, delivery of web content that based on self-identified area of interests. Add stool until liquid reaches red line on the transport vial. Transportation: Room temperature . However, rectal swabs are designed to sample beyond the anal canal at the columnar epithelium where the majority of enteropathogens reside. On some occasions, unpreserved stool is requested in order to isolate a known or suspected pathogen (i.e., culture for microsporidia, PCR testing). Ask him to tell you when he feels the urge to have a bowel movement. Although dry flocked rectal swabs have demonstrated equivalent performance to paired unpreserved bulk stool in the molecular detection of enteropathogens (3), it remains necessary to maintain bacterial viability in the preanalytic phase for antimicrobial susceptibility testing and serological typing. It can form the closed collection and transportation of stool specimen, which effectively prevents the drying, spill and leakage of stool specimen and is good for specimen marking, bulk delivering, and Sampling during specimen testing. Close the toilet seat on the collection hat. Stool samples should be collected in clean, leak-proof containers without disinfectant or detergent residue and with tight-fitting, leak-proof lids. An official website of the United States government. Here are just a few tips to ensure safety while transporting blood and specimens: If you are responsible for transporting blood or specimens, it is important to take measures to ensure the safety of the materials. That facility will refer specimens to CDC if necessary. Stool No recommendation Minimum volume is 1 gram No recommendation Refrigerate if delayed >1 hour, do not freeze Mainly for diagnosis of disseminated The new PMC design is here! Bethesda, MD 20894, Web Policies However, McNemars test of paired samples did not identify a significant difference in enteric pathogen detection between the FecalSwab and bulk stool collection methods for any of the enteropathogen targets (P>0.05). By following these guidelines, you can ensure that your samples will be transported safely and correctly. Frozen specimens thawing during transport b. Unspun specimens transported >2 hours from collection Specimen Collection Patient results are only as good as the specimen collected. Make sure that the transport vehicle is clean and free of contaminants. Evaluation of anatomically designed flocked rectal swabs for molecular detection of enteric pathogens in children admitted to hospital with severe gastroenteritis in Botswana. Consumable materials were generously provided by Copan Italia SpA (FecalSwab), BD Diagnostics (EVP and EBP kits), and New England Biolabs (reagents for laboratory-developed PCR). The primary container is then placed in a durable, watertight container referred to as the secondary container. Ideally, no medications should be taken immediately prior to or during the collection period. 0 When transporting medical samples, it is important to adhere to the proper temperature requirements in order to maintain their quality. Comparison of rectal swabs and faeces for real-time PCR detection of enteric agents in Rwandan children with gastroenteritis. Bars are representative of experimental triplicates and are presented as mean CT values SD from baseline. .

When transporting blood and medical specimens, it is crucial that you take the necessary steps to ensure their safety. Nelson's Saline Transport Media available upon request : Transportation: Room temperature . Sit on the toilet to have a bowel movement (poop) as usual. A stool specimen is a sample of the client's feces. 8600 Rockville Pike Molecular detection for the majority of viral targets (excluding astrovirus) was unaffected (change in cycle threshold [CT]1) by sample storage temperature over the 2-week period; however, detection of enteric bacteria was variable if specimens were not refrigerated (22C or 35C). We suggest that this physiological state permits C. jejuni to persist in stool specimens, which results in its molecular detection being unaffected by FecalSwab storage conditions. Eat a normal diet containing 50150 grams of fat per day for at least three days prior to beginning fecal collection. In this study, we considered the bulk stool volumes recommended by the manufacturer to have previously been optimized to prevent assay overloading (inhibition) and underloading (decreased clinical sensitivity). Using dry ice can be dangerous if not done correctly. specimen transport materials 13 . b. risk of contamination is higher with swabs. For the EVP and EBP panels, overall agreement was 99.3% (665/670 targets, = 0.97) and 99.5% (372/374 targets, = 0.98), respectively, suggesting equivalent detection between the two methods. This overgrowth is likely to have a negative impact on the viability of enteropathogens, especially fastidious organisms, as gastrointestinal flora can directly inhibit intestinal pathogens by competing for nutrients or by inducing the production of inhibitory substances (13). The sender must ensure that the specimen remains cold during transport by using available packing materials such as cold-packs. The device has the added benefit of transporting fecal specimens in small-instrument-ready tubes, saving space during transport and storage as well as enhancing laboratory workflow by facilitating automated processing. CDC follows regulations describing the requirements for proper packaging and shipment of biomedical materials (42 CFR Part 72 Interstate Shipment of Etiologic Agents) which can be located at https://www.cdc.gov/od/ohs/biosfty/shipregs.htm. Several primary containers can be placed in one secondary container as long as the combined volume does not exceed 50 ml. We considered a change in CT (CT) score from baseline (day 0) to be equivalent if 1 (6) and a CT of 1.1 to be a loss or less than or equal to a 1.1 gain in detection (Fig. Fecal components modulate human astrovirus infectivity in cells and reconstituted intestinal tissues, When pathogenic bacteria meet the intestinal microbiota, Comparison of FecalSwab and ESwab devices for storage and transportation of diarrheagenic bacteria. To simulate specimens received in the clinical laboratory, we prepared bulk stool samples differently for the EVP and EBP assays. The sensitivity of bulk stool for the EVP and EBP assays was 95%, whereas the FecalSwab demonstrated 100% sensitivity for both panels. Sensitivity of the collection method for detecting each enteropathogen target was calculated based on previous RT-PCR characterization by the clinical laboratory. In comparison to direct stool swabbing used in this study, rectal swabs collect smaller volumes of fecal material creating concern that these specimens could have decreased diagnostic sensitivity, especially when further diluted in the FecalSwab transport system. Although requiring further validation, results from this study and others (19) support the use of rectal swabs as a specimen type for the detection of enteric pathogens using the BD Max system. Evaluation of various FecalSwab sample volumes (10 and 50l) to achieve equivalent detection to the BD Max standard-of-care (bulk stool) protocols for each EVP and EBP pathogen target. This diet should be maintained throughout the collection period. Stool samples; Capillary tube samples; Samples for Platelet Aggregation studies, Platelet Function Analysis (PFA-100) and Thromboelastograph (TEG) . Integrating point-of-care specimen collection methods for diarrheal illness has the potential to improve sample return rates and expedite diagnosis, ultimately leading to improved patient outcomes and the initiation of appropriate infection control measures.

The BD Max system (BD Diagnostics, Baltimore, MD, USA) represents an ideal platform for integrating a FecalSwab specimen type due to its processing design and enteric diagnostic portfolio. Of 186 patients, 30 (16.1%) had no pathogen detected, and 156 (83.9%) were positive by at least one of the collection methods for an enteric virus (n=133) or enteric bacteria (n=93). Stool Specimens. The change in Shiga toxin detection was not as rapid as Shigella/EIEC, as a significant loss in detection was first observed on day 14 at 22C and on day 7 at 35C. Samples were excluded if the stool was solid (did not take shape of the storage container) or if there was limited stool remaining following standard-of-care testing. Experiments were performed using residual unpreserved stool specimens previously characterized using laboratory-developed multiplex PCR methods by the clinical microbiology laboratory. Estimates of the global, regional, and national morbidity, mortality, and aetiologies of diarrhoea in 195 countries: a systematic analysis for the Global Burden of Disease Study 2016. Enteropathogen detection traditionally relies on the collection of bulk stool; however, the inconvenience and time delays associated with attaining this specimen type can result in suboptimum sample return rates and/or delayed and missed diagnostic opportunities. National Library of Medicine Above weve provided some valuable links that will help you to understand government guidelines around a specific sample type. Stability studies were also performed to assess the potential of the FecalSwab to preserve nucleic acid in stool specimens for molecular enteric diagnostics. There are a number of different types of medical specimen containers, including: Each type of container has its own specific requirements, so be sure to select the correct container for your sample. Performance was equivalent (P>0.48) to bulk stool for all targets when 50l of FecalSwab specimen was loaded onto the BD Max assays. hb```\vVi``f`B)F\%NK0=A,-hh`hhn8d30{ i~@ G}-- ?&s4tJd`"f 9Bz It can be analyzed for the presence of blood; mucus; fat; microbes, such as bacteria and parasites; or other abnormal findings.
