Oral swab collection tips
Date: 2021-10-27
1. Preparation before sampling: Hand the sampling tube to the patient, let the patient hold the test tube, inform the patient that there may be discomfort during the sampling process, and at the same time inform the test tube that it needs to be held vertically, so that the patient can concentrate on holding the test tube, which can draw the patient¡¯s attention. Concentrate on tubes to reduce discomfort from nasopharyngeal irritation during sampling.

2. Body position during sampling: take a sitting or semi-recumbent position, with the patient's head slightly tilted, mouth wide open, and the patient's head resting on the wall or on the back of the chair to be fixed.

3. Standardize the sampling operation: Press the patient's tongue with a tongue depressor, and ask to make a long "ah-" sound. Pharyngeal swabs were performed on the patient's bilateral pharyngeal tonsils with "up and down three quick swabs" and "left and right three quick swabs" on the posterior pharyngeal wall to avoid contact with the tongue, teeth, and gums. If you feel unwell, quit after a while and try again.

4. Precautions: Drinking water before oropharyngeal swab detection will dilute the virus attached to the pharynx, especially drinking hot water will inhibit the activity of the virus. In order to improve the accuracy of throat swab nucleic acid detection, 15-30 hours before detection The patient was instructed not to drink water in minutes to ensure that the nucleic acid detection of throat swabs has high accuracy. For patients with good throat exposure, it is not recommended to grow "ah-" in order to reduce the occupational exposure risk of the sampler.
