Gently and slowly insert a minitip swab with a flexible shaft (wire or plastic) through the nostril parallel to the palate (not upwards) until resistance is encountered or the distance is equivalent to that from the ear to the nostril of the patient, indicating contact with the nasopharynx. Blood specimens are used for antibody (or serological) tests and, for some tests authorized by the US Food and Drug Administration that are used at the point-of-care, specimens are collected by pricking the skin with a fingerstick device. Remove the swab from the nose slowly and carefully while rolling it in your fingertips. These specimens may have decreased sensitivity, so caution should be exercised when interpreting negative results. Be sure to ask if there is a cost for testing and how long it will take to receive the test results. However, the induction of sputum is not recommended due to the possibility of aerosol production during the procedure. These swabs were tested for SARS-CoV-2 and shown to be negative. The nasopharyngeal swabs required for the coronavirus tests are quite different from your standard Q-tips and the exploding need for them has created a bottleneck in the soaring demand for.
