A negative serologic test result indicates that you have not developed detectable antibodies at the time of testing. This may be due to having testing performed too early in the course of COVID-19, the absence of exposure to the virus, or the lack of an adequate immune response. A negative test does not completely rule out a past or present infection with SARS-CoV-2 virus and correlation with a diagnostic test may be considered to look for an active infection. A negative result should not be used to influence social distancing, hand hygiene, or use of protective equipment decisions.
