Herpes Simplex 1 and 2 Blood Test
Herpes Simplex 1 and 2 Blood Test
The Welzo Herpes Simplex 1 and 2 Blood Test is a discreet, accurate diagnostic test designed to detect past exposure to the herpes simplex virus. Herpes is a common viral infection caused by two main types: HSV-1 and HSV-2, both of which remain in the body for life once acquired. While many individuals with herpes do not experience symptoms, the virus can still be transmitted and may cause intermittent outbreaks.
This test detects IgG antibodies to HSV-1 and HSV-2 in your blood, helping to determine whether you've previously been infected—even if you’ve never had a noticeable outbreak. Identifying herpes exposure is important for both your personal health and for protecting partners, as well as understanding the cause of symptoms such as recurrent sores, blisters, or unexplained genital discomfort.
This laboratory-based test uses immunoassay technology, similar to those used in clinical settings and supported by research from institutions such as University College London and the Centers for Disease Control and Prevention (CDC). Early and accurate diagnosis allows individuals to make informed decisions about treatment, transmission prevention, and overall sexual health.
What Does This Test For?
This test checks for past or current exposure to the herpes simplex virus by identifying the presence of type-specific IgG antibodies for HSV-1 and HSV-2. These antibodies indicate whether your immune system has encountered the virus before. HSV-1 is commonly associated with oral herpes (cold sores), but it can also cause genital infections. HSV-2 primarily causes genital herpes and is more likely to recur, particularly in immunocompromised individuals.
Even in the absence of symptoms, people can carry and transmit herpes. That’s why testing is often recommended for individuals who have had unprotected sex, multiple partners, or are experiencing unexplained oral or genital symptoms. The results can help clarify your infection status, support discussions with partners, and inform antiviral treatment options if necessary.
