DNA Sample Collection Types:

Cheek Buccal Swabs:

Buccal (cheek) swabs follow the standard, non-invasive method used to acquire a genetic sample when performing a paternity test. The participant gently rubs a specialized cotton swab on the inside of their cheek to collect buccal cells. This collection approach is simple, quick, painless and yields DNA accuracy comparable to blood samples for comparative analysis.

Blood Samples:

Blood draws, while also highly accurate, require phlebotomy procedures that can cause discomfort to the participant. Thus, cheek swabs present a patient-friendly alternative for procuring DNA when establishing genetic relationships.
