Description of the blood test:

The HSV 1/2 IgG test is a laboratory study used to detect “memory” antibodies against Herpes Simplex Virus types 1 and 2. Type 1 is typically associated with oral herpes (cold sores), while Type 2 is more commonly linked to genital herpes, though both can affect either area. The presence of IgG antibodies indicates that the body has encountered the virus in the past and has established a lifelong carrier status. This test is essential for determining a patient’s immune history and assessing the risk of future outbreaks or transmission.

What does the analysis represent?

• Purpose: Qualitative or quantitative determination of IgG antibodies to HSV-1 and HSV-2 in blood serum.
• Primary application: Identifying chronic carrier status, assessing immunity before pregnancy, and differential diagnosis of skin and mucosal lesions.
• Performance: High-precision enzyme immunoassay (ELISA) of a venous blood sample.

Recommendations for the test (General)

• Time: Blood collection is recommended in the morning.
• Fasting: A food intake pause of 4–8 hours is required.
• Rest: Stay in a calm state for 15–20 minutes before the procedure.
• Important: A positive IgG result does not mean an active outbreak is occurring right now; it only confirms that the virus is present in the body in a latent state.

What can affect the results?

• False-positive results: May occur due to cross-reactivity with other viruses in the herpes family (e.g., Varicella-Zoster).
• Early Testing: If the test is performed too soon after initial exposure (the “window period”), IgG antibodies may not have developed yet.

When to take the test?

• Recommendations: Prescribed for individuals with a history of recurrent sores, couples planning a pregnancy, or those experiencing unexplained neurological symptoms.
• Preparation: Standard preparation for serological tests; avoid alcohol 24 hours prior.

How to interpret the results?

The interpretation of data is the exclusive responsibility of an infectious disease specialist, urologist, or gynecologist. The presence of HSV IgG antibodies is not a diagnosis of an active clinical disease. The physician analyzes these values in the context of the patient’s symptoms and frequency of relapses. Only an expert can determine if current symptoms are related to the herpes virus and whether suppressive antiviral therapy is necessary to maintain health and prevent transmission.

Possible further investigations

• HSV 1/2 IgM: To check for signs of a recent infection or an active reactivation.
• HSV PCR (Swab): To detect the actual virus on the skin or mucosa during an outbreak.
• Consultation with a Urologist: For the management of genital symptoms and reproductive health.
• Consultation with a Neurologist: If there are concerns about the virus affecting the nervous system.

When does the next step make sense?

Knowing your HSV status is a vital part of personal health management. If the result is positive, the next step is a professional consultation to discuss how to manage the carrier status and reduce the risk of future flare-ups.
