Harm? Other than your insurance company may not pay for it, none that I'm aware.
Help? Maybe. From all the research I've done, the HPV test is not all telling. It's possible that you've had a strain and naturally cleared it long before you took the test. Remember, many HPV infections go away on their own with little or any harm done.
We've made the decision to get vaccinated and then go about our lives as normal, knowing that there isn't much you can do to prevent the other stains. Something like 25 % of people with active HPV infections have enough on their hands on a day-to-day basis to infect others.
