When I did Bella's test, I suited up like someone from CSI Miami with lab coat and nylon gloves, and poor Bella didn't have anything to eat for 12 hours previously, LOL! I was bound and determined to get the largest and purest DNA sample that I could with the cheek swab. The results were impeccable, like uncorking a bottle of fine wine .

Does the blood test go back more than 3 generations, do you know?
