It is not possible to give a specific answer to the question of what are the chances of being positive for a novel coronavirus infection after a pending review. Pending review means that the nucleic acid test results are rechecked because there is a possibility of false positives or false negatives in the nucleic acid test, and it is usually done for those who are positive in the initial screening or those who are positive in the mixed test. There is no way to tell if a person will be positive for novel coronavirus infection after the review, and there is no way to give a chance. If the person is positive in the initial screening, there may be a positive or negative result in the review, but the patient who is positive for novel coronavirus infection needs to undergo a nucleic acid test and a combination of antibody tests to determine whether he is diagnosed or is asymptomatically infected. In the case of a positive test for novel coronavirus infection in a mixed test, the test results will need to be reviewed to find out who is positive for novel coronavirus infection and further testing will be required, and all other people in the mixed test group will need to be tested and quarantined accordingly in order to avoid infection with the novel coronavirus.
