Paternal Lineage DNA Test

Endeavor DNA offers confidential, accurate, fast, and affordable Y-STR paternal lineage testing services.

Y-STR testing determines whether two males share the same paternal lineage. The Y-STR paternal lineage DNA test is based on the fact that the Y chromosome is passed from father to son relatively unchanged through many generations. Only males can undergo Y-STR testing because females do not possess a Y chromosome.

Y-STR paternal lineage testing determines whether or not Y-STR markers are consistent, or not consistent, with the conclusion that the tested males may be related through a common male ancestor.

Y-STR analysis cannot distinguish a specific relationship between males who belong to the same paternal line. However, it is useful for excluding males from an alleged biological relationship.

For example, if a male child and his alleged uncle (alleged father’s full brother) are tested, their Y-STR profiles must match. If they do not, then the alleged uncle is excluded (not considered a biological uncle) and the alleged father is probably not the biological father.

Endeavor DNA offers a 3-5 business day turnaround on Y-STR paternal lineage tests utilizing either buccal swabs or specimen collection cards (WhatmanTM FTA® or WhatmanTM 903) with rush testing options available. Endeavor DNA can also test a multitude of other sample types, but longer turnaround times may apply.

All Endeavor DNA paternal lineage tests utilize stringent, validated testing procedures and include up to 23 Y-STR loci in order to achieve 100% accurate results.
