Re: A test to see if your body has CLEARED the hpv virus causing genital warts.
There is a test, the "Digene HPV DNA Test". It is typically only used in persistent HPV cases, such as the kind that causes cervical cancer, or for those who have had chronic recurrences of warts and have struggled to clear the virus on their own. In your case, even if a doctor had the test available, they would more than likely not subject you to the procedure. It is very expensive... around $1500 out of pocket. That, and most health insurance providers won't cover the procedure for the evaluation of a non-cancerous variety of HPV. I posed your exact same question to my doctor and health insurance provider back when I was in your position, and I was met with that exact response.
Based on what you have described, you more than likely have overcome the condition on your own. According to the CDC, 90% of cases clear on their own within two years (70% of cases within one year). Count back to the month when your symptoms disappeared, and tally up the total number of months that you have been without symptoms up until the present day. If you haven't had symptoms on over a year, you are more than likely fine. Just make sure that you are upfront with your partners, so that they can play an equal part in their health decisions. After having undergone the proper treatments to overcome the condition, you may actually be a safer option than someone who has simply never been screened but continues to sleep around.
