Hi there,
It's not clear if you still have warts or not, and it seems as if you were never diagnosed with HPV/genital warts. If you do have symptoms that you think are warts, your health care provider can usually tell you simply by looking at them closely (sometimes with a magnifying lens).
HPV testing is only approved for use in a clinic to check the cervix, so it isn't a general means of figuring out if you have HPV beyond the cervix specifically. Still, for most individuals the immune system is able to clear HPV pretty well, and you can read more of the discussions we've about that at
http://www.ashastd.org/phpbb/viewtopic.php?t=394. HPV can lead to recurrent warts, but this usually doesn't happen many years after the last episode.
Hope this helps,
Fredo
