The basis of genetic testing is relatively simple. By matching the genetic markers of the mother and the child, a laboratory can determine which genetic markers the child received from the mother. It then attempts to match the remaining genetic markers of the child with the tested man or men. If the tested man has the required genetic information, he is a possible father. If he does not, he is not a possible father.
Genetic testing is a quick and painless way to establish paternity.
It is especially useful if there is any doubt in the minds of the mother or the alleged father as to issue of paternity. The CSEA generally uses the buccal swap method by which a genetic sample can be collected by swapping the inner facial cheek. This procedure is painless and relatively non-intrusive. The samples are collected by a trained technician. Butler County CSEA currently contracts with LabCorp to collect genetic samples and performs genetic testing on the same.
