China Mobile sent a message that my nucleic acid test was abnormal. What happened?

Abnormal nucleic acid results mainly refer to unqualified test results, including possible false positives or false negatives, but it does not mean that the nucleic acid test results must be positive. There are sample problems, reagent problems and subjects problems that affect the results.

1. sample problem: nucleic acid detection is usually carried out by means of oropharyngeal swab and nasopharyngeal swab. If the sample acquisition amount is insufficient, atypical or poorly preserved, it will lead to errors, which will lead to abnormal nucleic acid results and false positive or false negative.

2. Reagent problem: Some laboratory reagents will be used for nucleic acid detection. If there is something wrong with the reagent, such as the reagent is expired or not used in time after opening, the exposure time is too long or the reagent is obviously damaged, these factors may lead to abnormal nucleic acid detection results.

3. Problem of the examinee: The examinee touches the detection tool, or when sampling the examinee, the examinee fills in the wrong ID number or name in the nucleic acid, and the detection result is inconsistent with the personal information of the health code platform, which may lead to abnormal detection results.

An abnormal nucleic acid test result in COVID-19 means an abnormal nucleic acid test result, and a second or more nucleic acid tests are needed to explain whether COVID-19 is infected.
