How accurate are the herpes tests?

Depends on the test. So we have a couple of tests.One is a polymerase chain reaction test (PCR) for herpes that we get when we scrap the lesion.Another test is a blood test that detects the body's antibody response to an infection by the Herpes Virus.Regarding the PCR test it is very accurate but it depends on getting a good DNA sample from the scraping.The blood test depends on the antibody response time. DNA better.

How accurate are home herpes tests? (it is a blood test) are they just as accurate?

Why do you ask? Even the antibody tests from big labs are not altogether sensitive or specific. Many folks have the antibodies but no lesions so probably cannot infect others. Read more...

How accurate are type specific herpes tests?

Very. A positive HSV I and/or HSV II antibody titer is diagnostic for prior exposure to that specific virus. While nothing is always100% it is unlikely that antibody titers for these 2 viruses would be misleading. Read more...

How accurate are type specific herpes tests? What are my chances of false negatives?

Herpes simplex. There are very few medical reasons to get such testing since most of us already have this virus. The newer type specific tests are far more accurate than previously. Cannot answer about false-negatives because not sure which test you are referring to. This is an issue best discussed with your PCP. Good luck and hope this helps. Read more...
Accurate. These assays are highly sensitive (91%–100%) and specific (93%–100%) for HSV-1 and HSV-2 infection, even in the absence of symptoms. Thus, a negative result suggests absence of infection. A positive result strongly suggests infection with HSV. In presence of strong suspicion of exposure (for example partner with known HSV 2), a negative test should be repeated in 4 -5 weeks. for confirmation. Read more...
PCR is the best test. Serologic blood tests for antibodies can differentiate HSV-1 from HSV-2. However, if this is a recent infection it may take several weeks for serology to be (+) for HSV. Culture of the lesions will usually be (+) if you have a blister or ulceration due to HSV, but can give false negative results. Polymerase chain reaction(PCR) tests for HSV DNA and is much more sensitive(few false negatives) Read more...
