Who Your Baby Daddy?

Have you slept with 10 guys in 2 weeks and now find that you're pregnant? You probably haven't a clue as to who the father is. And guys, is there something about your new baby that just screams "it's not yours"? Well, worry no more, just stop at Rite-Aid and pick up a do-it-yourself DNA test.

Now you can buy a paternity test at any of 4,363 Rite Aid drugstores, thus exposing your suspicious mind or perhaps your cheating heart to the person on the other side of the counter.

The tests, marketed by Utah-based Identigene, employs a DNA fingerprinting technique similar to those used to solve crimes. They were introduced in Rite Aid stores on the West Coast last fall, and after 10,000 of them flew from the shelves, the company decided to market them in Pennsylvania, New Jersey and 27 other states, plus Washington, D.C.

For millennia, uncertainty over paternity has shaped sexual mores, allowing some men to escape the burden of child care and helping women cheat without detection. That's all changing now, as paternity DNA testing is easier than ever.

For up to $29.99 plus a $119 lab fee, customers can pick up a kit, scrape a few cells from the cheek of the child, mother and putative father, then send it to Identigene, where it's analyzed and sent back within three to five business days.
