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 is right if you're testing purely for your own peace of mind — a cheek swab, mailed in, private results. If the result needs to matter in a Los Angeles County courtroom or a child support proceeding, the legal version is required instead, using a supervised, chain-of-custody collection that a court can rely on without dispute.

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 Californiacourts & agencies
California requirement

In California, a DNA test done through an at-home kit or a privately chosen lab is generally not valid in court and is not enough on its own to establish legal parentage; establishing legal paternity requires either a signed Voluntary Declaration of Parentage or a court-ordered genetic test following chain-of-custody procedures, and this legal determination must be made before a court can issue orders for child custody, visitation, or child support.
