“My ex-girlfriend contacted me to say that I may be the father of her 5 year old daughter. Your test proved that I am the true biological father. It’s a life changer. Thank you.”

Jared, SD

“I was very impressed with the ease and discretion of the testing process. I received my results quickly and quietly.”


“My husband has always mentioned that our two children maybe did not belong to him and accused me of being involved with his friend at the time that our children were conceived. I knew that this was not true. We finally decided to get a paternity test done to put an end to this. Sure enough, the results of the paternity test indicated greater than 99.9999% that he was the father of our children. Our family is now closer than ever before.”

R. Stern, Seattle, WA

“A++++. Near the date that my test was scheduled to be completed, I was so nervous that I ended up calling your lab almost once every hour. Thank you for putting up with me. I won’t forget your kindness.”

G. Lopez, NY, NY

Can a DNA test determine if Siblings have the Same Father?

A DNA Sibling test will show you whether siblings are full siblings (same mother and father), half siblings (only one parent in common), or not related.

A DNA sibling test is not as powerful as a DNA paternity test and should only be considered when it is absolutely impossible to test the alleged father (if the alleged father is missing, deceased or absolutely refuses to be tested). While a DNA paternity test will also give you an absolutely conclusive answer regarding paternity, sibling tests can only give you a likelihood ratio which indicates the likelihood that siblings are full, half or not related.
