However, all tests, including the COVID-19 antibody test, can produce negative results that are incorrect (i.e., false negative results). Ct values are not comparable between tests and may not be comparable between different lots of the same test, as they are dependent on various factors such as the specimen collection, storage, transport, time from collection, nucleic acid target, primers and probes, extraction method, amplification method, instruments used, etc. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website.
