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. Doctors 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.
