Herpes Testing – HSV Type 1 & Type 2 Test
Herpes Testing – HSV Type 1 & Type 2 Test is a laboratory test you can request directly. This test detects antibodies in your blood that indicate exposure to the herpes simplex virus types 1 and 2. These viruses are common causes of oral and genital herpes.
What this test is
The Herpes Simplex Virus (HSV) antibody test looks for specific proteins your immune system creates in response to HSV-1 and HSV-2 infections. These antibodies can help determine if you have been infected with either type of the virus.
What it measures
- HSV-1 Antibodies — reflects exposure to the herpes simplex virus type 1
- HSV-2 Antibodies — reflects exposure to the herpes simplex virus type 2
What the test involves
This test requires a blood sample, which is typically collected through a standard venipuncture procedure. A healthcare professional will draw blood from a vein in your arm.
Why it is often ordered
A clinician may order this test if you have symptoms suggestive of a herpes infection, such as sores or blisters. It can also be used to confirm a previous diagnosis or assess past exposure to the virus.
Preparation
No special preparation is usually needed for this test. You should follow any specific instructions provided by the laboratory where your sample will be collected.
How results are reported
Results will indicate the presence or absence of antibodies for HSV-1 and HSV-2. Reference ranges for interpreting these results can vary between laboratories.
Before you go
- Ask about sample collection requirements.
- Inquire about the typical turnaround time for results.

FAQ
Frequently asked questions
Can this test tell me if I have an active herpes infection?
This test primarily detects antibodies, which indicate past or current exposure. It may not always distinguish between a recent and a past infection. Your doctor will consider your symptoms and other factors when interpreting results.
How soon after exposure can antibodies be detected?
Antibody levels may take several weeks to develop after initial infection. If you have symptoms, your doctor may order a different type of test that can detect the virus directly.
What does it mean if my test is positive for HSV-1 and negative for HSV-2?
A positive result for HSV-1 antibodies suggests you have been exposed to or infected with the herpes simplex virus type 1. A negative result for HSV-2 means antibodies for that specific virus were not detected.
Are there different types of herpes tests?
Yes, there are different types of herpes tests. This test looks for antibodies in the blood. Other tests may look for the virus itself in fluid from sores.
