Herpes Tests: How It Is Done

How It Is Done

For a viral culture, viral antigen test, or PCR test, a clean cotton swab is rubbed against a herpes sore to collect fluid and cells for examination. Samples may be collected from the vagina, cervix, penis, urethra, eye, throat, or skin. Health professionals usually collect a sample from small sores that are only a few days old. Viruses are more likely to be found in small newly formed sores.

For an antibody test, the health professional drawing blood will:

• Wrap an elastic band around your upper arm to stop the flow of blood. This makes the veins below the band larger so it is easier to put a needle into the vein.
• Clean the needle site with alcohol.
• Put the needle into the vein. More than one needle stick may be needed.
• Attach a tube to the needle to fill it with blood.
• Remove the band from your arm when enough blood is collected.
• Put a gauze pad or cotton ball over the needle site as the needle is removed.
• Put pressure to the site and then a bandage.
