Collecting Samples for a Home DNA Test

At-home DNA kits make it possible for people to have a convenient and affordable way to learn more about their ancestry and potential health concerns as well as perform a paternity in a mostly anonymous setting. Fathers that wish to reassure themselves can purchase a test and make certain their DNA is a match with their child. It is also a way for mothers to confirm the father of their child.

Streamlining the Procedure

Blood samples were once considered the most accurate method of DNA testing but there were a lot of costs with this option. The blood sample required refrigerated storage and special handling and issues like sterile and safe collection made home testing unlikely. Saliva testing has proven to be easier, more affordable and just as accurate. It does not require the refrigeration and the sampling process is painless.

Collecting a Sample

Buccal swabs are included with a home dna test. These over-sized cotton swabs are designed to reach easily into the mouth for a sample of cheek cells. Only a small amount of saliva is needed because of the microscopic size of DNA. Over a million threads of DNA could be lumped together to fit into the space of single 12-font period. Swiping the cheek puts the DNA-filled saliva into the swab material where it will dry and then be extracted in a laboratory by destroying the fatty membranes around each cell.

Choosing Alternative Collection

Sometimes it is not possible to collect a saliva sample to prove paternity. There are alternate methods but there is no guarantee there will be enough DNA for an accurate result. Any item that may contain the saliva of the subject can be swabbed. This includes a letter they sealed, a cigarette butt or an unwashed drinking container. Only their saliva should be on the swabbed item to prevent inconclusive results.

Paternity tests done at home will provide people with enough information to pursue custody, child support or just feel confident that they are genuinely biological family members. It is an affordable method of reassurance that takes only a couple of weeks from start to finish. The tests are very accurate as long as the instructions are carefully followed.
