What’s tested
Pick a time
This blood test detects IgM antibodies against Herpes Simplex Virus Type 1 (HSV-1), helping to identify a recent or active infection. It is suitable for anyone concerned about possible HSV-1 exposure, including those with symptoms such as cold sores or oral lesions, or individuals needing clarity before or during pregnancy. The test requires a simple blood sample, collected by a trained phlebotomist.
Herpes Simplex Virus Type 1 (HSV-1)
- HSV-1 IgM antibody: The presence of IgM antibodies typically indicates a recent infection or reactivation, as these are the first antibodies produced by the immune system after exposure. This test is particularly useful when symptoms are present or when there is a known recent contact with the virus.
Why it matters
Early identification of HSV-1 infection allows for timely management, reduces the risk of transmission to others, and helps prevent complications, especially in vulnerable groups such as newborns and immunocompromised individuals. Knowing your status also supports informed decisions about antiviral treatment and safe practices.
No special fasting required. Drink plenty of water prior to your appointment for a smooth blood draw.
- Identification: Photo ID (Passport or Driving Licence) is only required if you need your report for official, employment, visa/travel, premarital, or Identity-Verified Certificate (IVS) purposes (not required for personal health & wellness testing).
