Re: Will The type specific blood test be accurate
In the United States, there are only 3 FDA approved tests for diagnosing herpes; HerpeSelect, RapidBioKit HSV-2, and the Captia EIA. There is also the WesternBlot. Although the WesternBlot is not FDA approved, it's considered the 'Gold Standard', a reference test and how all others test get FDA approval. The HerpeSelect comes in two flavors, the ELSIA which returns a numeric result for hsv1 and/or hsv2 and the Immunoblot which returns an easy to read 'negative' or 'positive' for both hsv1 and hsv2. All of these test are type specific for HSV 1 and/or HSV2, although the RapidBioKit and Captia only test for type 2 (HSV2). The HerpeSelect test is the most common, all of these tests mentioned are IgG type specific.
The bottom line on testing is waiting. The recommendation from all bloodtest makers is waiting at least 12-16 weeks. Although some people can seroconvert (turn positive) as early as 3 weeks, most will take about 6-8 weeks, and everyone else (who will be turning positive) will tricky in after that. And yes, there are the rare individuals who can take longer than 4 months, sometimes 6 months or longer. These people usually have a preexisting case of hsv1, which is know to delay the ability of the bloodtest to detect the hsv2 antibodies. So, the longer you wait the higher the accuracy of a negative result.
The test to avoid is the IgM bloodtest; it not type specific and can not accurately determine if your infection is recent, reoccurring, or even if you have the herpes antibodies at all. Many doctors still order this test, they are misinformed and using outdated information about this test to draw conclusions. Do not assume your doctor know's best about proper herpes testing.
There are some HSV common test, which test for either hsv1 or hsv2. Personally, I think these are worthless, cause it doesn't give a complete story. If you were in a car accident, and told you have a broken bone, wouldn't you wanna know which bone was broken. I think of these common type tests as an older style of testing, there accuacy isn't as good as the current FDA approved IgG type specific tests like the HerpeSelect brand.
One problem with bloodtesting is; it can tell you what type of HSV infection you have, hsv1 and/or hsv2, but it doe not reveal the location. While the norm is oral hsv1 and genital hsv2, the number of genital hsv1 cases is on the rise because of oral sex.
When/if order a on-line test, they'll have you go to a local lab for the blood draw.
Regardless of where you go, or who draws your blood, MAKE SURE you get hard copies of the results. That way you can post your results if you have questions about the actual test you had or the results.
