Is there a blood test for herpes 1?

Is there a blood test for herpes 1?

1) There is only one reliable and commercially available type of blood test for herpes antibodies called a Type Specific IgG. This test can reliably distinguish between herpes 1 and herpes 2 antibodies. There are labs that will run tests that are not type specific, but these are essentially useless.

Where can I get a negative test for herpes?

We use one of the UK’s leading pathology laboratories, where all tests have been internally validated and are either UKAS accredited or an application for accreditation has been submitted. If you have herpes but the virus is not active, this is likely to produce a negative result on the tests offered (other than the IgG antibody blood test).

Is it possible for a herpes test to be inaccurate?

It’s always possible for a test to give inaccurate results. The accuracy of a herpes blood test depends on two things. The first is how many people in the tested population have herpes. The second is which specific test was used.

How long does it take for a blood test to turn positive for herpes?

2) Blood tests take 3-6 months to turn positive after exposure because it takes 3-6 months for your body to make IgG antibodies in response to an infection. 3) There is no blood test that can tell you immediate exposure/recent infection. Some less than scrupulous labs and providers might tell you to get an IgM test.

What kind of blood test is herpes simplex 2?

(Cheers to open communication.) From there, the two of you have blood tests and ask to be screened for STIs, including both types of herpes: herpes simplex virus type 1 (HSV-1), which most commonly causes oral herpes, and herpes simplex virus type 2 (HSV-2), which most commonly leads to genital herpes.

How often are herpes blood test results correct?

That’s the virus primarily associated with genital herpes. 3  In that scenario, the positive predictive value and negative predictive value are as follows: HSV-1: Approximately 92% of positive tests give the correct result. HSV-2: Approximately 92% of positive tests are correct, and 98% of negative tests are correct.

What does a positive blood test for herpes mean?

Blood test If you get a “positive” result from the viral culture or PCR tests, it likely means you have herpes.. A “negative” viral culture or PCR result could mean you don’t have genital herpes. But in some cases, a person could still have genital herpes and a negative result.

How long does it take for a positive herpes IgM test?

The test is a simple blood test, and results are usually available within a week. Although it takes time for this test to become positive, herpes IgM is one of the first types of antibody to be made after an infection.
