Can tests for genital herpes give a false-negative result?

ANSWER

Cell culture or PCR test may give a false-negative result if the sores have begun healing or if you are recently infected. It takes several weeks for HSV antibodies to show up in the blood. A false-negative test shows you don't have the condition when in fact you do. False-positive test results are possible, too. If you test positive, but your risk for getting the virus is low, you may need to be tested again.
