There isn't a blood test for hpv or herpes. If your asymptomatic you're asymptomatic. So yeah....I forgot my point.....time to go back to the bottle then to jerking off.
Actually, this is wrong and you're spreading bad information. There is, in fact, several Herpes blood tests available. As technology has advanced, so to has the specificity and reliability of these tests. There is one known as Herpes Select and I believe a few other labs (which any doctor can draw up orders for) will distinguish between Type I and Type II. While it's true Type II is most often associated with genital herpes, there have been increasing rates of Type I genital herpes due to the increase in oral sex. Yes, giving a blow job while having a cold sore (or history of one) can pass along the virus to your partner. These newer tests look at IgG antibodies are should be considered much more reliable than IgM tests which are notorious for false positives - especially for those who have had mono or chickenpox. The gold standard for Herpes and Type testing is the Western Blot - the same type of test used to confirm HIV diagnosis in patients who initially test positive on a screening test. The Herpes Western Blot test is current conducted at the University of Washington so you have to facilitate your blood draw and get the sample there.
As with most things - knowing your own status can have a real impact on the spread of the disease. Most HIV infections are spread during the "window" period when a person's viral load is astronomically high and would actually show up as negative on many screening tests. (Most HIV tests are accurate at about the 6 week mark - a special DNA PCR test which actually measures HIV itself and not antibodies can identify a positive result within a week of becoming infected).
And, when you go in for your regular check ups and ask for an std panel/screen, herpes is rarely included. Even as a gay male I've had to specifically make sure I have both the HSVI IgG and HSV2 IgG antibody test done as well. So, just because someone says they had a test and are clean, you might want to dig a bit deeper and ask if they were tested for Hepatitis, Herpes, Syphilis, and swabbed for DNA culture of HPV, or if they simply peed in a cup to screen for Gonorrhea and Chlamydia along with a semi accurate HIV screening test.
It's your health. In the gay world, it's just easier to assume every contact is positive or has something until you get confirmation otherwise. It takes two to tango and both partners bear responsibility in ensuring a safe sexual encounter. And, to their credit, gay folk do tend to sero-sort, a process by which knowing one's own status means you'll only engage with others with the same status/virus. This makes "the talk" a genuine non issue and removes some of the stigma. I still know gay friends who'd pick HIV over herpes, which blows me away, but it's funny how we treat a twice a year cold sore in our genitals - however painful or uncomfortable - as a the worse of a sometimes terminal, and very costly disease which will completely - albeit more slowly these days - break down your body.
Got off on a bit of a rant - sorry about that. But, please, get tested - and demand from your doctor to be tested for everything you want so that you can be informed. Hell, one of my boyfriends and I went in together when we first began dating and getting serious and it allowed us to be open and honest with each other on another level and have a grown up conversation about the risks of sex whilst not in the throws of passion seconds before insertion.
Here is a great link to information about Herpes and where I source some of the information in my post. In re-reviewing the site, it actually reports DNA culture of the blister itself is the most accurate/sure fire way to know if its Herpes and its type. However, if there isnt enough DNA present, the blister has now scabbed over, etc, you can get a false negative. Which brings us back to the blood tests. Read it, share it with others. Excellent info.
