Pregnancy will not affect the results of the nucleic acid, it is negative if you are not infected with the new coronavirus and will show positive if you are infected with the new coronavirus. Nucleic acid is used to determine negative and positive by testing the DNA gene sequence, pregnancy does not cause changes in the DNA gene sequence, therefore, pregnancy will not affect the nucleic acid results. The absence of Neo-Crown virus infection is considered negative, while the opposite is considered positive. It is recommended to avoid nucleic acid within 48 after receiving the booster shot of Neo-Crown vaccine so as not to affect the test results. In addition, pregnant women should take good personal protection during the epidemic by avoiding places where people gather, wearing masks when going out, and washing hands before meals. Pregnant women should go to the hospital for regular checkups to detect any abnormalities in the fetus and treat them in a timely manner.
