Whether drinking alcohol for nucleic acid has any effect needs to be judged according to the time when the patient drinks, if the patient drinks before the nucleic acid test, it may affect the test results. If you drink alcohol the day before the test, there is usually no effect, and you should pay attention to your diet before the nucleic acid test. If the patient goes for the nucleic acid test just after drinking, it may cause the alcohol residue to have an effect on the test results. If patients drink alcohol the day before the nucleic acid test, having the nucleic acid test at this time will generally not affect the results. Patients are advised to avoid drinking alcohol prior to the nucleic acid test so that the alcohol does not enter the body as well as the bloodstream, which could affect the nucleic acid test results. Patients should avoid spicy and stimulating foods such as chili peppers, ginger and onions before the nucleic acid test to avoid symptoms such as vomiting. Doing nucleic acid testing immediately after drinking alcohol may have an effect, and doing nucleic acid after the alcohol is metabolized usually has no effect. Patients should avoid drinking alcohol before doing the nucleic acid test to avoid affecting the test results.
