The nucleic acid test is the first hurdle to confirm the new coronavirus. I want to get tested, but my throat is a little inflamed, so will a nucleic acid test for throat inflammation be positive?
1. Will a nucleic acid test for throat infection be positive?
Inflammation of the throat does not usually affect the results of the nucleic acid test. The nucleic acid test is a specific test for the new coronavirus, and its results are not determined by the body's symptoms. If the throat infection is not caused by the new coronavirus, there is no need to worry about a positive test.
2. Do I have to repeat the nucleic acid test?
The test can be repeated for people who are at high risk. Because the results of the nucleic acid test may appear false negative, and this will occur, mainly with the performance of the kit or individual new coronavirus load sampling site, sampling volume, sampling level, as well as laboratory testing conditions and personnel operations, some individual special cases, the viral load is very small, etc. may also lead to the causes are very complex, so high-risk groups can consider repeatedly Nucleic acid testing can be done several times to make the accuracy rate higher.
3. How long is a nucleic acid test valid?
Generally speaking, if the nucleic acid test is negative, the validity period recognized by the institution is about 3-7 days, because almost all people do not have immune antibodies against the new coronavirus, which means that in the absence of antibodies, they can be infected by the new coronavirus at any time, and if they have been in a safe area, they usually do not need to be rechecked, so there is no clear expiration date for the nucleic acid test.
4. Under what circumstances is nucleic acid testing necessary?
①. If you have been to or have traveled to a high-risk area.
②. In the case of having traveled or lived in the area where the case continues to spread before the onset of the disease.
③, have close contact with patients with fever or respiratory symptoms from the infected area.
④. have engaged in some high-risk infection work, such as doctors, quarantine personnel, etc.
⑤. In the case of having some obvious symptoms of new coronavirus infection, such as having fever and imaging features of pneumonia, etc.
