i been trying to find out what is considered a low risk and when its considered high risk HPV.
Is is possible for HPV not be detected in an STD test?
Because my girlfriend had an std test and came out clean, but about 6-7 months later i started showing warts growing in certain parts( like little groups of them) of my penis.
can some one be immune to it and still carry HPV?
There are over 100 strains of HPV. More than 20 strains affect the genitals (including anus and/or mouth). Those strains are basically subdivided into high risk and low risk HPV. Low risk HPV leads to genital warts. High risk HPV can lead to cancer if undetected and/or untreated.
HPV is not checked in a standard STD test. A woman can be check for HPV when she gets her pap test, but it isn't always done (for many reasons). There is no FDA approved test to detect HPV in men.
It is possible for HPV to cause problems in one person, but not another.
You can read more about HPV by going to the Center for Disease Control website and searching for HPV.
High-risk are those strains that can go on to cause cancer. Low-risk strains don't.
HPV is not usually checked for during STD tests. It is usually diagnosed from a PAP test/swabs for women and swabs for men (high risk), or a visual + vinegar solution wash for men and women (low-risk/warts).
STD testing is not like it's one test, they have to test for everything individually so it's actually a bunch of tests and HPV is not usually among them, unless it's specifically requested.
