The testing is performed by collecting buccal cells found on the inside of a person's cheek using a buccal swab or cheek swab. These swabs have wooden or plastic stick handles with a cotton on synthetic tip. The collector rubs the inside of a person's cheek in order to collect as many buccal cells as possible. The buccal cells are then sent to a laboratory for testing. For paternity testing, samples from the alleged father and child would be needed. For maternity testing, samples from the alleged mother and child would be needed.
