Is it a problem that Zhuhai nucleic acid results didn't come out the next day?

Nucleic acid test results are generally updated within 12 hours, and there may be a delay if there are many samples.

Situation description:

1, the nucleic acid detection agency usually submits it within 12 hours, depending on the time of the detection agency.

2. In the case of large-scale nucleic acid detection in this area, it may be delayed.

3. The results of nucleic acid testing need to be reported to the health department's nucleic acid database system in time and accurately by the testing institution before they can be displayed in Yuekang code in real time. If it is urgent to show the results of nucleic acid test, it is recommended to contact the testing institution to obtain a paper or electronic version of the nucleic acid test report.

Why is there a false negative in nucleic acid detection?

At the initial stage of virus invasion, the amount of virus in human body has not reached a detectable level. In different periods of virus incubation period, mild symptoms and severe symptoms, the viral load in different parts of the human body will be different. Therefore, the difference of sampling time and sampling place may lead to insufficient viruses in the collected samples; Any detection reagent has its lower detection limit. If the virus in the patient's specimen does not reach the detection limit of the reagent used, false negative will appear. Poor performance of laboratory instruments and equipment, poor detection ability of personnel and inadequate implementation of quality management will also produce false negatives; The sampling is not standardized, the collection place is inappropriate, and the collected samples are atypical, resulting in too few or no cells infected by the virus in the samples. That is, it may cause false negatives.
