How soon the nucleic acid test results are available is related to the outpatient clinic situation and patient category. According to the “Workbook for Novel Coronavirus Nucleic Acid Testing in Medical Institutions (Trial Version 2)”, fever outpatients and emergency patients should report nucleic acid results within 6 hours. For general outpatients, inpatients and companions, etc., results should be reported in principle within 12 hours. For other populations, results are usually reported within 24 hours. However, with the improvement of testing capabilities in medical institutions, nucleic acid tests can now generally produce results in a few hours, so there is no need to worry too much. In addition, you can consult with the testing facility before testing to clarify the time for the results of the nucleic acid test and make reasonable travel plans. Some people who have been to high-risk areas should pay attention to self-protection and isolation while undergoing nucleic acid testing, and try to avoid going to public places with large crowds. Wear a mask daily, wash your hands frequently, isolate yourself at home and wait patiently for the nucleic acid test results. If the nucleic acid report is negative, daily protection is sufficient. If the nucleic acid report is positive, you should actively go to a medical institution for retesting, and those who are confirmed will need to be isolated and treated.
