The nucleic acid test report does not need to be stamped. Nucleic acid testing is now free and self-funded. Generally, we can get the results the next day, so if the results come out, we can prove whether there is novel coronavirus. This doesn't need to be stamped. The patient test report has the doctor's electronic signature and does not need to be stamped. This report is valid.

Matters needing attention in nucleic acid detection:

Before nucleic acid detection, attention should be paid to avoid gargling with sterilized mouthwash, which may kill pathogenic viruses in the mouth and affect the accuracy of the detection results.

It should be noted that eating should be avoided 2 hours before nucleic acid detection, because the pharynx should be fully exposed during nucleic acid detection, and the pharyngeal secretions should be dipped for inspection, which can stimulate the pharyngeal reflex and cause nausea, vomiting, cough and other symptoms. Smoking, drinking, chewing gum and other behaviors that may affect the detection results should be avoided 30 minutes before sample detection.
