Y-STR DNA Testing

Description:
Y-STR testing compares Y-chromosome markers between males to determine whether they share a common paternal lineage.

Purchaser Information:

• The test is generally performed between two or more male participants.
• Y-STR testing evaluates paternal-line relationships and does not provide the same information as an autosomal paternity test.
• For legal cases, Y-STR testing should be performed in addition to appropriate autosomal relationship testing when required.
