A swab/culture is always a good way to diagnose, really trumping a blood test if you're symptomatic. The problem with a blood test is it truly does not 100% verify the location. For instance, let's say you have genital symptoms, and a week or so into them you go to get checked out. You get a blood test but no swab, and the test comes back positive for HSV1. Here, you could have HSV1 orally already, and your genital symptoms were actually yeast or irritation, for example. So now you've labeled yourself with genital herpes, and in fact you have it orally. HOWEVER, let's say you got in to see the doc in time to get a swab/culture of an active lesion. The doc swabs it, it comes back positive for HSV1. Now you know FOR SURE that it's genital herpes. The only caveat here would be if you tested positive via blood test for HSV2. In that case, it most likely is genital.
So, truly - seeing your medical provider as soon as you have what may be an outbreak, and getting it swabbed/cultured/typed, is the way to go. Otherwise going with an IgG type specific test is reliable, it just may not always pinpoint the location of the infection.
best bet is go see your dr. immediately after if it comes back. he will swab it and you will know for sure. If not, wait for teh blood test.
how often have you heard of herpes being just 1 bump.
could be, go have an IGG blood test 3 months from the exposure.
