When traditional swabs (such as spun fiber, foam, or flocked) are not available, 3D printed swabs may also be considered (see additional FAQ below on this page). Please contact CDC at respvirus@cdc.gov prior to submitting specimens to confirm. At present, the diagnosis of coronavirus disease 2019 (COVID-19) is made through a nasopharyngeal swab based on reverse transcription polymerase chain reaction (RT-PCR) technique. A specimen that is not collected correctly may lead to false or inconclusive test results. Other information that must be provided to the laboratory when requesting a test includes the sex and age or date of birth of the patient; the test(s) to be performed; the specimen source; the date and, if appropriate, the time of specimen collection. This is important to preserve both patient safety and specimen integrity. 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. Clean the puncture site with a 70% isopropyl alcohol pad and allow it to air dry. Insert the swab head into a sterile transport media tube, snap off the swab handle at the break-point, seal the cap, and label the sample (Fig 4). Flocked nylon fibers provide greater surface area to collect and absorb secretion, and is also more comfortable than many alternatives. While FDA and the clinical community have vast experience with traditional swabs, there is limited prior experience with the use of 3D printed swabs for specimen collection for diagnostic testing. ESwabs in Amies media are not a valid specimen type for COVID-19 testing. Some diagnostic tests use other samples such as mid-turbinate, nasopharyngeal,. Do not use calcium alginate swabs or swabs with wooden shafts, as they may contain substances that inactivate some viruses and may inhibit molecular tests. The most common tests for COVID-19 are PCR tests, involving a nose and throat sample taken with a cotton swab. A: All transport media should be sterile to avoid contamination of the specimen. Note: This paper is intended as an overview on the topic of sampling swabs and not as an authoritative how-to guide. If it is unavailable for purchase, CDC has posted a standard operating procedure for the preparation of VTM. Stop when you feel resistance at turbinates (see fig 8).

It contains segments from the RdRp, E, and N (including both N1/N2 targets) genes. Manufacturers of 3D printed sterile swabs are required to comply with quality system regulation (21 CFR Part 820). There are three main kinds of Covid nasal swab tests: nasopharyngeal (the deepest), mid-turbinate (the middle) and anterior nares (the shallow part of your nose). A: For anterior nares specimen collection, the entire tip of the swab 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. Take approximately 15 seconds to collect the specimen. For diagnostic testing for current SARS-CoV-2 infections, CDC recommends collecting and testing an upper respiratory specimen.
