Residents who test themselves for antigens at home should report to the community in their area if they are positive, and the community should notify the emergency center to call the 120 special ambulance to transfer the patients who test positive for antigens in a closed-loop manner to the medical institutions with the conditions for nucleic acid testing and then to conduct nucleic acid testing, and then enter into the process of management of infected persons if they test positive for nucleic acid.
Tips to do home antigen test residents, if antigen test positive, all used swabs, test tubes, test cards must be in a sealed plastic bag, in the staff door to door must take this away to the health care institution, in accordance with the treatment of medical waste.
Note: The general population should not do antigen testing at will
Our country has approved antigen detection reagents with a sensitivity of 75%-98%, and a specificity of between 95%-99%. Because of our better epidemic prevention and control measures, the prevalence of the population in most parts of our country is less than one in a million. If you take a kit with a sensitivity of 85% and a specificity of 97% to a city with a population of 10 million people for screening, you will get 300,000 positives, but only 9 out of the 300,000 positives are true, which means that most of them are false positives, but of course the results of the test that is negative are reliable. If you go to a population with a prevalence of 5% and use a kit with 85% sensitivity and 97% specificity, you do about 60 out of 100 positives that are true, with no more than 1% missed. Therefore, antigen detection should be used in high-risk, high-prevalence aggregated infection of the population detection, the general population do not feel free to do antigen detection.
