Abnormal nucleic acid detection due to weather

1. Problems in the sample: In general, nucleic acid detection is carried out by methods such as nasopharyngeal swab and anal swab. If the samples collected during detection are insufficient, atypical and poorly preserved, it may lead to abnormal results such as false positive or false negative;

2. Problems with reagents: When doing nucleic acid detection, laboratory reagents are usually used. If there are problems with reagents, such as expired reagents, damaged reagents, and long-term non-use after opening, it may lead to false positive or false negative results in nucleic acid detection. At this time, it is necessary to do personal protection and go to the detection point in time for nucleic acid detection again;

3. The examinee's question: If the examinee is infected with the virus, the virus can be detected during the nucleic acid test, resulting in a positive test result. At this time, it is suggested to report to the community in time and cooperate with doctors for isolation treatment.

Nucleic acid detection refers to the technical method of qualitative, quantitative, sequencing or homology detection of nucleic acid by hybridization. It is suggested that personal protection should be done during nucleic acid testing, so as to avoid too many close conversations with others and not to go to places where people gather.
