Two types of herpes tests
Blood tests detect herpes simplex virus (HSV) antibodies produced by the body in response to infection. Blood tests can detect herpes even if there are no symptoms present. These highly accurate tests can determine whether a person has HSV-1 or HSV-2.
Culture tests are used to detect the herpes virus itself. A sample of fluid from a herpes blister or sore is collected and placed on a culture dish in a laboratory to see if the virus will grow. Culture tests are usually less expensive than blood tests, but they are also less reliable, especially if the sore has already started to heal.
It’s important to note that not all herpes tests are created equal, and discussing which test is best for you with your healthcare provider is essential.
