It is convenient and quick to detect COVID-19 antigen on the test paper through the binding reaction between antigen and antibody, and the result can be obtained in 15-20 minutes. However, the antigen-antibody reaction will be false positive due to some interference, and the specificity of the method can not reach 100%. Therefore, the antigen test results cannot replace the nucleic acid test results.
What should I do after antigen testing?
No matter whether the test result is negative or positive, the used novel coronavirus antigen kit should be treated as medical waste, and it can be disinfected with alcohol first if possible.
