PCR Testing: The Gold Standard
Polymerase chain reaction (PCR) testing is currently the most accurate method for diagnosing genital herpes. It involves taking a sample from a sore and detecting the virus's DNA. PCR is favored for its sensitivity and can distinguish between HSV-1 and HSV-2.
Viral Cultures: An Alternative Method
Viral culture tests involve growing the virus from a sample taken from an active lesion. While effective, the sensitivity is lower compared to PCR, especially as sores begin to heal. Cultures are usually processed within five days, providing a timely diagnosis.
Serologic Tests: Detecting Past Infections
Serologic tests identify antibodies to HSV in the blood. They are useful for identifying past infections, even without current symptoms. However, these tests cannot determine the location of an infection, whether oral or genital.
