False positive nucleic acid considerations may be related to the laboratory environment, substandard practices, and other reasons.
1. Laboratory environment: Some laboratories performing nucleic acid testing have a substandard environment, and specimens sent for testing are contaminated by viruses in the environment, which may lead to false positives for nucleic acid.
2. Non-standard operation: the operation is not standardized when conducting nucleic acid test. The probe of the test kit is contaminated, and false-positive results may also occur.
Although false-positive nucleic acid tests exist, they are still needed to diagnose novel coronavirus infections. When performing nucleic acid testing, try to follow the normal regular process to reduce the incidence of false positives.
