Do siblings share a MOTHER/FATHER?
A brother to sister (sibling to sibling DNA Test) works by testing a very large number of different DNA points (known as loci) in each person. Full siblings share a lot more DNA in common than do unrelated persons, and also, half siblings share more DNA in common than unrelated persons, but not as much as full siblings. So this test looks at the amount of DNA sharing and uses DNA statistics to evaluate the amount of DNA sharing to deduce biological relationship. Because we are evaluating the amount of DNA sharing, it is helpful to have DNA from any parents or other siblings of the persons being tested, since that drastically helps the evaluation process by allowing us to pin-point exactly which DNA is more likely to have come from each sisters Father in particular.

Our Relationship test is performed to determine whether two or more individuals are biologically related.
We compare the DNA of two people to determine which relationship is best supported by the amount of DNA they have in common. For example, if two people are known to share the same mother, our Relationship DNA Testing can be used to indicate the likelihood of them having the same father. We can see if their DNA profiles are more consistent statistically with them being half-siblings or full siblings.
A wide range of relationships can be considered and the testing can be performed on males and females (grandparents-grandchildren, siblings etc).
