The person being tested just happens to have a bowel movement, and the stool specimen is sent for testing. 2. Sampling by health care workers in the anus with a swab, method is: the patient lying on the bed, health care workers take a swab in one hand and insert the swab into the patient’s anus 2~3cm for sampling, the detection process does not need to be detected by the hands of the person, only need to relax, deep breath, take the initiative to cooperate with health care workers, you can complete the test. The practice of anal swabbing is exactly the same as nasal swabbing and pharyngeal swabbing except for the different parts, the other steps are exactly the same, and the results of the test are also the same. Regardless of whether the anal swab or throat swab is collected, it is necessary to go to a specialized hospital for testing and to cooperate with the health care provider during the test.
