False negative in COVID test: Here are three possible reasons for a false negative result
0views


Considering the sensitivity and surge in cases globally, people are getting COVID-19 tests done to negate fears. Early preventive tests can also cut down the risk of exposure. However, one must know that timing is key with COVID tests and there are chances of getting false positives and negatives.

Unless and until you exhibit symptoms, or have been exposed to a COVID+ positive person, getting a COVID test done is not advised.

Antigen tests, which are used for serosurveys as well could be rather helpful. However, if a person gets negative on antigen tests, despite considerate exposure, an RT-PCR test is then advised. Otherwise, there is no real reason for you to get an RT-PCR test done.
