Two kinds of testing

Which test do you actually need?

Most people don't realize there are two different tests until they start looking — and they serve very different purposes.

A private at-home test fits if you're testing purely for personal certainty — a self-collected cheek swab, mailed in, private results. If the outcome needs to matter in a Delaware County court case or a child support proceeding, the legal version is required, with a supervised, documented collection process built to hold up as evidence.

Court & Legal Use

Legal Testing

A supervised, chain-of-custody collection — required if the result needs to hold up in custody, support, or immigration matters.

  • Photo ID verified at collection
  • Witnessed, documented process
  • Accepted by Pennsylvaniacourts & agencies
Pennsylvania requirement

In Pennsylvania, at-home DNA test results are not accepted as legal proof of paternity; courts and child support agencies require a chain-of-custody genetic test performed at an accredited facility, with witnessed collection and identity verification, before parentage can be legally established.
