Often times a person may meet another person and find out they may share the same biological parent. When situations like this occur.Believe it or not, there are many people who are not aware that there is a DNA Test that can help determine whether or not two or more siblings are biologically related. 

The name of this type of Test is known as a Sibling DNA Test. In this post, we will answer all of the frequently asked questions from our clients regarding Sibling DNA Testing.

Frequently Asked Questions:

Can you do a paternity test with a  Siblings?

Yes. In order to perform this DNA Test, the alleged father of the siblings must partake in the DNA Test.

No. Each person and every person on earth’s DNA sequence is unique to themselves. This also applies to Siblings.

Now, there is one slight caveat. Identical Twins! Identical Twins share the same DNA.

How much is a Sibling DNA Test?

The cost of sibling DNA test starts at $395.00. please contact one of our DNA testing experts for appointments at 646-902-1497.

Do half brothers share the same DNA?

Half brothers or sisters only share the DNA from the common contributing parent. Half brothers/siblings would share the identical Y Chromosome that would be passed down from only their father. Daughters do not inherit Y Chromosomes from their fathers. Mother’s pass down mitochondrial DNA to their offsprings (sons and daughters).

What makes you a half brothers or half sisters?

What determines a half sibling is sharing a common parent’s DNA (mother or father).

Can a DNA Test prove Half Sibling?

Yes.

What is the turnaround time for a Sibling DNA Test? 

The average turnaround time for a Sibling Test is 2-3 business days from the date the lab receives all DNA samples involved in your case.

I just met someone I believe maybe my sibling. What do I need to get started? 

The ideal scenario for DNA Testing for Half Sibling DNA Test would be to have the alleged siblings being tested have their non-common parent of each sibling tested. In most instances, the non-common parent would be the mother.

The reason we suggest including the non-common parent in a Sibling DNA Test it helps increase the accuracy of the Sibling DNA Test by identifying the contribution of the non-common parent. The lab will then be able to analyze the remaining of the alleged common parent in each sibling and compare them. 

In the event, the non-common parent is not available to be tested. A Sibling DNA Test can still be accurately performed.
