The main difference between a new crown pending review and a confirmed diagnosis is that a new crown pending review is not yet a confirmed diagnosis and needs to be tested again, whereas a confirmed diagnosis means that it has been infected with the new crown virus. New Crown pending review means that the first nucleic acid test for New Crown was positive, and in order to avoid false positive nucleic acid test results, a retesting organization is needed to retest, and does not mean that the nucleic acid test for pending review has received a confirmed result. A new crown confirmation, on the other hand, is when two or more nucleic acid tests are positive, representing that a new type of crown pneumonia has been present. It is important to note that for people who need a nucleic acid retest, a positive test result can only be determined if both the initial and retesting organizations are positive. If there is a discrepancy between the retest result and the initial test result, then further testing is required and a conclusion is drawn in conjunction with an epidemiologic investigation. Since the recent vaccination with the new Crown pneumonia vaccine may also result in a positive nucleic acid test, the vaccination should only be tested after 48 hours, and any discomfort should be treated by a doctor in time.
