1, information error: when making nucleic acid, the registration information is wrong. Even if the result is detected, the nucleic acid result cannot be directly found because of the information error.
2. Time from the start of detection: After the completion of nucleic acid detection, the results will generally be available after 6 hours. If the time from the detection is short, the result cannot be found. It is also possible that the results may be delayed because of too many specimens.
