The testing process is simple—the DNA samples are taken using a painless buccal (cheek) swab, and testing is completed in 5 business days. We can either send you a testing kit to collect your DNA samples at home, or if there are legal implications, we can use a Chain of Custody collection process where a trained professional near you will take your DNA samples.
