COVID 19 RAPID ANTIGEN TEST

“This COVID-19 test detects certain proteins in the virus. Using a nasal swab to get a fluid sample, antigen tests can produce results in minutes. Others may be sent to a lab for analysis.A positive antigen test result is considered accurate when instructions are carefully followed. But there’s an increased chance of false-negative results — meaning it’s possible to be infected with the virus but have a negative result. Depending on the situation, the health care provider may recommend a RT-PCR test to confirm a negative antigen test result.” by William F. Marshall, III M.D.
