The following specimen collection guidelines follow standard recommended procedures. Myth 4: Testing is extremely uncomfortable because the swab has to go super deep into your nose. For anterior nares specimen collection, the entire tip of the swab (usually to of an inch) should be placed inside the nose, and the side of the swab tip should be rubbed with moderate pressure against as much of the wall of nares region as possible, moving the tip through a large circular path inside the nose.

For additional information, see the FDA's Letter to Health Care Providers, issued October 7, 2020, on providing clear instructions to patients who self-collect an anterior nares nasal sample in a health care setting for SARS-CoV-2 testing. Insert the swab through the nostril, and keep it parallel to the palate, not upwards (Fig 2). Per CDC recommendations, the swab should be made of a synthetic material with a flexible wire or plastic shaft. Due to concerns with specimen stability, transport, and appropriate collection materials, self-collection at home or at sites other than designated collection sites staffed by HCPs is currently only permitted with tests authorized explicitly for use in these settings in the EUA. Apply firm pressure to the puncture site with clean gauze for five to ten seconds after collecting the specimen to ensure bleeding has stopped. While there have been swab shortages to fill the urgent need of COVID-19 testing, care still needs to be taken to qualify and source the best swab for the type of sampling that is required. Anterior nares sampling collects a nasal secretion sample from just inside the nose. That means in the general .

As with all swabs, only grasp the swab by the distal end of the swab, using gloved hands only. Many ITM contain guanidine thiocyanate or similar chemicals making them incompatible with certain in vitro diagnostic platforms, including those that use bleach (sodium hypochlorite), and with laboratory processes that use bleach. Many molecular influenza (flu) virus and respiratory syncytial virus (RSV) tests require the same components as many SARS-CoV-2 molecular assays. Any facility (including a hospital, laboratory, or other site) that manufactures any swab intended to be used for diagnostic testing must meet applicable medical device regulatory requirements, including Registration and Listing (21 CFR Part 807), medical device reporting (21 CFR Part 803), reports of corrections and removals (21 CFR Part 806), and applicable quality system regulations (21 CFR Part 820).

Quest specimen requirements and acceptable supplies for SARS-CoV-RNA (COVID-19), Qualitative NAAT (test code 39448) Diagnostic Laboratory of Oklahoma (DLO) and Quest Diagnostics do not manufacture the collection supplies used in testing. Despite the discomfort, with the omicron variant of the virus quickly spreading, tests are in high demand. Learn more to see if you should consider scheduling a COVID test. Each pellet contains A549 lung epithelial cells. Chemtronics offers the Coventry Sterile Flocked Swab (part #66010ST, see fig 7) that has been engineered to efficiently collect biological fluids for elution and analysis. 3D printed swabs are required to meet the general labeling requirements for medical devices. Store respiratory specimens at 2-8C for up to 72 hours after collection. These concerns should be considered in the evaluation of 3D printed swabs for use in COVID-19 testing. This product is intended for use with Xpert Xpress SARS-CoV-2 assay on the GeneXpert Systems (Cepheid). Microfiber provides high surface areas for rapid capillary absorption of fluid specimens. The isolate is USA-WA1/2020, chemically inactivated. These swabs were tested for SARS-CoV-2 and shown to be negative. Dispose of used fingerstick collection devices and lancets immediately at the point of use in an approved sharps container. COVID-19 testing swabs are typically made out of synthetic fibers such as polyester, rayon, viscose and nylon. The HSC should yield a positive result with the RP primer and probe set and negative results with all 2019-nCoV markers.

On October 13, 2020, FDA issued the Enforcement Policy for Modifications to FDA-Cleared Molecular Influenza and RSV Tests During the Coronavirus Disease 2019 (COVID-19) Public Health Emergency. In the early days, it was the nasopharyngeal swab the swab that went way, way up the nose. The assay should not react to this negative control, but the CDC reagents did at many, but not all, state labs. Laboratories should confirm the specimen has been obtained correctly and from the individual that is being tested. Cookies used to track the effectiveness of CDC public health campaigns through clickthrough data. Please refer to the COVID-19 Viral Transport Media Policy for FDA's policies concerning alternative types of sterile transport media intended for use with molecular RT-PCR SARS-CoV-2 assays.

Also called a molecular test, this COVID-19 test detects genetic material of the virus using a lab technique called reverse transcription polymerase chain reaction (RT-PCR). A: Based on the available evidence at this time, the FDA believes that the following specimen types are appropriate for swab-based SARS-CoV-2 testing: Although all of the above options are appropriate for clinical testing, nasopharyngeal specimens are generally considered to yield the most sensitive test results and are therefore the preferred choice as a reference (comparator) for clinical investigations and validating new methodology. The single-use combination test kit uses a self-collected nasal swab and produces results in 30 minutes with an accuracy rate over 90% for influenza A and B and Covid, according to the FDA. Genome modifications and editing are available. As noted above, analytical testing can be performed to confirm compatibility with individual platforms.

The isolate is USA-WA1/2020, chemically inactivated. DNA plasmid: Please note that if a DNA plasmid control is used, a method to evaluate performance of the reverse transcription step should be included. Nasal mid-turbinate sampling collects a nasal secretion sample from inside the nose. Samples for COVID-19 diagnostic tests are typically collected using an anterior nares (nasal) swab sample. As a general matter, 3D printing can introduce certain challenges not seen with conventional manufacturing. But recent data and FDA approvals have shown that saliva can do an equally good job in an appropriate clinical setting. Lab personnel should also exercise caution if you cannot identify the type of transport media in the specimen collection tubes or if you do not know whether the transport media contains guanidine thiocyanate or similar chemicals as an ingredient, since warnings apply and special precautions should be taken for such ingredients (see the answer to the question regarding alternative types of transport media below).

Carefully insert the swab head into the posterior pharynx and tonsillar areas (Fig 6). Chemtronics offers theCoventry Sterile Flocked Swab (part #66000ST, see fig 1) that has been engineered to efficiently collect biological fluids for elution and analysis. See warning below. Specimens can be collected from both sides using the same swab, but it is not necessary to collect specimens from both sides if the minitip is saturated with fluid from the first collection. Clear & Sure VTM Kit. There is not a single formulation that these types of media use, and they can consist of proprietary formulations intended to enhance inactivation and stabilization performance. At least four of these sweeping circular motions should be performed in each nostril. When the bleach interacts with the guanidine thiocyanate in the transport media, it produces dangerous cyanide gas. Additional information about the policies in this guidance can be found on FDA's FAQs on Viral Transport Media During COVID-19 webpage. Having a state-issued identification card available at the testing site will speed up the process immensely; however, no identification documents are required.
