Abnormal nucleic acid results are mainly the result of a failed test, including the possibility of false positives or false negatives, but it does not necessarily mean that the nucleic acid test result is positive. There are sample problems, reagent problems, and problems with the person being tested that can affect the results.
1. Sample problems: Nucleic acid tests are usually performed by means of oropharyngeal swabs and nasopharyngeal swabs, etc. If the samples are insufficiently obtained, atypical, or poorly stored, resulting in errors, this can lead to abnormal nucleic acid results, resulting in false positives or false negatives.
2. Problems with reagents: Nucleic acid testing uses some laboratory reagents. If there are problems with the reagents, such as the reagents have expired or the reagents have not been used in a timely manner after they have been opened, they have been exposed for too long, or the reagents have been significantly damaged, all of these factors may lead to abnormal nucleic acid test results.
3. Problems of the tested person: the tested person touches the testing equipment, or when sampling the tested person, the tested person fills in the nucleic acid with the wrong ID number or name, and the test result fails to match with the personal information on the health code platform, which may cause abnormal test results.
Abnormal nucleic acid test result means that there is an abnormality in the nucleic acid test result, and a second or more nucleic acid tests are required to indicate whether or not the person is infected with the New Crown virus.
To summarize, abnormal nucleic acid test results may be due to the above factors, after such results, in order to ensure the accuracy of the test, a second standardized nucleic acid test should be conducted at a later date, and the person to be tested should follow the doctor’s instructions to prepare for the nucleic acid test before the test.
