DNA and paternity testing in Tempe.

An informational paternity test compares DNA to evaluate a biological father-child relationship for personal knowledge. Choose a legal test from the start if you need identity verification and chain-of-custody documentation for an official purpose.

The key difference is the collection and documentation process. An informational test is intended for personal knowledge. A legal test includes verified identities, witnessed collection, and documented chain of custody for an official purpose.

A self-collected informational kit does not establish the witnessed identity and custody documentation generally required for legal use. If you need a result for court, arrange a legal collection before samples are taken. An informational result cannot simply be relabeled as a legal test afterward.

A standard paternity comparison tests the child and alleged father. The laboratory may recommend or require a sample from the biological mother depending on the case. Tell us who is available and whether any possible fathers are related before choosing a test.

A siblingship test evaluates evidence for a biological sibling relationship. Results can vary in strength and may be inconclusive. Additional family samples can sometimes help, so describe the known relationships when arranging testing.

A sterile swab is rubbed along the inside of the cheek to collect cells. Standard postnatal relationship testing generally uses cheek swabs. Call to arrange the collection method for your informational test, and use witnessed collection if you need legal documentation.

Price and turnaround depend on the relationship being tested, number of participants, and whether collection is informational or legal. Call (480) 210-1016 for a quote and current timing. Tell us about any court deadline before scheduling.
