It is possible to get a nucleic acid done in the morning after waking up. Doing a nucleic acid is actually an abbreviation for performing a nucleic acid test, which is a general term for deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). At the infectious disease level, each pathogen has a unique nucleic acid sequence. For this reason, a nucleic acid test can be used to quickly identify infection with certain pathogens. There is no time limit for the nucleic acid test, so it can be performed in the morning, at noon or in the evening. However, it is generally recommended to wait 48 hours after vaccination with the new coronavirus vaccine before performing the nucleic acid test. It is important to wear a mask, take personal precautions, and keep a social distance when performing the test. Whether it is an oropharyngeal swab or a nasal swab, it is important to take appropriate actions in accordance with the requirements of the medical staff in order to avoid cross-infection.
