Sibling Test

Put simply, a DNA test for siblings is designed to determine if two or more people are fully related, share one parent or aren’t related at all.

How it works: One of our trained consultants will take a cheek-swab sample from each person being tested. (Or you can have a kit mailed to you and have it done at home, sending the swabs back to the lab for testing.)

The technicians will then examine the DNA to find various genetic matches. Through this test — using either 16 genetic markers or 22 — we will be able to tell you if those tested are full siblings, meaning they have the same two parents, or half-siblings, meaning they share just one parent. It will also reveal if they don’t share any of the same genes.

Our fees for sibling testing are as follows:

• Legal OFFICE siblingship 16 – 22 marker test (1 mother, 2 siblings): $400
• Non-legal OFFICE siblingship 16 – 22 marker test (1 mother, 2 siblings): $320
• Non-legal HOME siblingship 16 – 22 marker test (1 mother, 2 siblings): $225

Testing mom is recommended but always optional.

These results are sometimes used as proof in court for those seeking Social Security benefits, child support, visitation rights or other claims.

FaceIT DNA offers a special type of sibling DNA test called DDC’s PlatinumPlex, which examines more markers and can provide results that are more than 1,000 times more powerful than a standard 16-marker test. Call us today to discuss whether your situation calls for this type of sibling testing. Put our expertise to work for your peace of mind!

Each human being has 23 paired chromosomes in their genetic profiles. Half of everyone’s genes comes from the mother, and half comes from the father. So when a sibling DNA test is performed, it’s very helpful to be able to test not only the alleged siblings, but also the mother. This way, the DNA that matches all three participants can be moved out of the way to focus on the remaining genes.

At FaceIT DNA, we treat every one of our cases with the utmost respect, care and confidentiality. We offer high-quality sibling testing at a fair price, because we want to be available to anyone who needs one.

With more than 6,100 locations nationwide, you can rest assured that your case will be taken care of quickly and accurately. These days, it’s no longer necessary to live with uncertainty about biological relationships. We’re here to help provide answers for you!
