What is a Y chromosome DNA Test?

In contrast to DNA testing for the rest of the human body, only a small amount of DNA from the Y chromosome is needed to complete a genetic test. A Y chromosome DNA test is also called Y-STR. It looks for mutations in the male sex chromosome that are passed down from father to son. There are many reasons why a man might want to take this type of test, but it is most commonly used as an alternative for a paternity test when an alleged father is unavailable.

When two males who belong to the same paternal line share the same Y-STR, no distinct relationship can be identified. This method can be used, however, to exclude males from an alleged biological relationship.  

How much does the Y DNA Test cost?

The cost of a Y STR DNA test started at $395.00 and up. To order this test or to schedule an appointment. Contact our office today at 877-680-5800 to get started.

When will I receive my Y STR DNA test results?

The turnaround time for your results to be completed is between 1 to 3 working days.

How accurate is Y-STR DNA testing?

A Y chromosome DNA test can accurately determine if two alleged male relatives share the same Y-chromosome lineage.

Can a female perform a Y Chromoe some test?

No. As stated earlier in this post. Only men have a Y chromosome and therefore this type of DNA test would not be ideal for a female child to be tested with an alleged biological father to determine paternity.

Alleged fathers and daughters can only perform a paternity test to establish paternity. If you would like to schedule or purchase this testing option. Please contact our office today at 877-680-5800 to get started.
