Nucleic acid testing can be done in pregnant women, and the test has essentially no effect on the fetus and does not affect the results of the nucleic acid test. Nucleic acid testing is usually done by taking specimens from the nasopharynx and oropharynx and obtaining mucus from these areas for testing for the presence of nucleic acids from the new coronavirus. It can be seen that pregnancy does not affect the results of nucleic acid testing, and that the taking of the specimens is basically unaffected to the pregnant woman and the fetus. In the process of taking the specimen, there may be irritation causing temporary discomfort in the nose or throat, and very few people will have nausea and vomiting, which will soon recover and have no effect on the fetus, so there is no need to worry too much. Try to avoid eating 2 hours before the nucleic acid test to avoid nausea and vomiting during the sample collection. You should wear a good mask properly and keep a social distance while waiting for the collection.
