Determine Your Daddy—at the Drugstore

The sometimes vexing task of determining a child's father can now be solved by plunking down $29.99 at the local drugstore. A Utah company has expanded sales of its do-it-yourself DNA kit to Rite Aids in 30 states after sales soared in sample markets, MSNBC reports. Identigene of Salt Lake City expects to sell 52,000 of them this year.

The kits, which don't require FDA approval, include swabs to collect DNA samples from the cheeks of the child and the parents. The material is sent to a lab, which emails the results back within a week (for another $120). The company says the accuracy rate is 99%, but legal experts say results may not hold up in court for now. Critics say such genetic testing is too important to be sold in such an informal way and want government oversight. (More paternity test stories.)
