Siblingship DNA Test (2 Individuals): Specimen Type: Buccal Swab
A sibling test can verify if two people are likely to be full or half siblings. It is impossible to determine with 100% certainty whether two people are siblings without having one or both of the parents involved. However, DNA tests can tell if two people are likely to be biologically related. It’s a test that can be requested by a parent or the siblings themselves (if they’re over the age of 18 or a legal guardian is giving consent for the minor(s) involved).
You do not need DNA from a parent to do a sibling test, however if you do have a parent willing and able to provide a sample, it will produce more accurate results. If a mother is unable to participate in the DNA test, a grandparentage test may be more definitive.
This is how it works in all relationship DNA tests – the more people willing and able to be tested, the merrier (and the more accurate the test results)!

Amelia was unknowingly adopted at the age of three by a loving couple who was wholly dedicated to providing a happy, healthy, and safe home for their daughter.ther.
When many people think of laboratory blood tests, they imagine making an appointment at their doctor's office, taking time off work, paying large fees, and waiting around in the lobby for who knows how long.
How Does A Sibling Test Work?
As an individual, 50% of your genes came from your mother and 50% came from your father. If you have a full sibling, they too received 50% from your mom and 50% from your dad.
But unless you’re twins, you don’t look alike! That’s because genes express themselves differently in people.
Let’s pretend a gene is like a dice. It’s one block with six different sides. (In genetics this is called an allele. Although, genes don’t necessarily have 6 variations. This is just an example.)
When a child is conceived, it’s like both the mother and father rolled the dice. For you, say the dice landed on a 2 and that’s why you have brown hair… but for your sibling it landed on a 4 and that’s why he’s a redhead.
Although you and your sibling have genes expressing themselves in unique ways (one shows a 2 and the other shows a 4), you received the same set of genes (the same dice were rolled) from the same two people and DNA testing can verify that.
In the case of a half sibling, you won’t have as many genes in common. However, DNA tests can look and see if there are enough matching genes to prove you share a biological mother or father.
