Drinking alcohol before a nucleic acid test will generally not affect the results. Generally 75% concentration of alcohol can kill the virus, which is the concentration of industrial alcohol. And the human body to drink alcohol generally does not reach this concentration, and after drinking alcohol residue in the oral cavity is relatively low, not enough to have a negative impact on the virus, so it will not affect the nucleic acid test. Nucleic acid test, in addition to being widely used for the detection of new coronavirus, can also be used for the detection of HIV, hepatitis B virus and hepatitis C virus. In addition, drinking alcohol will easily lead to a decline in body resistance, which will increase the risk of infection with the new coronavirus, so it is recommended not to drink alcohol before the nucleic acid test. At the same time, the new coronavirus has a relatively fast contagious, so you need to pay attention to good care work. If there is any discomfort, consult a doctor in time.
