It is possible that antigen testing may be affected by alcohol, and alcohol contact with the specimen may lead to false-negative results for some antigen tests, but personal alcohol consumption does not usually affect test results. Alcohol has a strong bactericidal effect, especially at 75%, on both viruses and bacteria, and also destroys proteins, causing them to coagulate. There are many types of antigen tests, some of which detect viruses or bacteria directly, and some of which detect certain components of viruses or bacteria. These antigenic components, when exposed to alcohol, are likely to be damaged and a false negative test result will occur. However, if you do an antigen test after drinking alcohol yourself, it usually does not affect the results. When you need to do antigen testing, you should first go to the Laboratory to do specific counseling to see the precautions, if the antigen test will be affected by alcohol, you need to be out of contact with alcohol for a certain period of time before the operation, to avoid detection errors.
