Nucleic acid test results for the new coronavirus that have not been available for 72 hours may be due to the high number of people tested, or it may be due to incorrect information about the tested person, abnormal test results, etc. that need to be reviewed. The patient should wait patiently for the result and avoid going out during this period. The nucleic acid test for the New Coronavirus is currently an effective method of detecting New Coronavirus infection, and it takes about 4 to 6 hours or more from sampling to test results, so it is understandable that the number of people tested at the same time may result in a longer waiting time, and the results may not be available for more than 72 hours. In addition, if the basic information of the examinee is incorrect, such as cell phone number, ID card number and other registration entry errors, it will make the testing organization unable to correctly upload data and synchronize the results, and thus unable to check the nucleic acid report. In a few cases, there may be abnormal test results leading to delayed results, such as a failed specimen or a positive result from a mixed test tube, at which time the testing organization or CDC will generally contact the individual to resample the test. Therefore, there is no need to worry too much, just wait patiently. If a person does not receive their nucleic acid results within 72 hours, they can call the testing organization to find out why. Try to avoid going outside while the results are pending to avoid widespread spread of the virus.
