New York ? You can “check in” to restaurants and bars, so how about health clinics while you get tested for sexually transmitted diseases?

Foursquare, the phone application for telling friends and strangers where you are, is offering a special virtual “badge” in September to people who do just that.

The badge is part of MTV’s “GYT: Get Yourself Tested” campaign. MTV says the idea is to remove the stigma attached to getting checked out for STDs.

Foursquare and similar services use smart phones’ GPS capabilities to locate where users are and what’s around them. Users can then “check in” to a venue by tapping it on a list — or typing in their own.

Foursquare users already receive scout-inspired merit badges for a range of check-in accomplishments. These include “Gym Rat” for hitting the gym 10 times in a month or “Crunked” for checking in to four or more places in a single night.

Stephen Friedman, the general manager of MTV, said he expects that some people will decide to get the badge despite the social stigma surrounding STDs. And once they do, their friends may, too.
