A sibship test determines whether two children share one or both parents.
Sibship testing is a DNA test performed to determine if two children share one or both parents (i.e. if they are half-siblings or siblings of father and mother). It is an indirect way of determining family relationships when an alleged father is not available for a paternity test.
Sibling 1 and Sibling 2 who do not share the same mother and want to find out if they share the same biological father - in this situation, a half-sibship test is conducted.
Sibling 1 and Sibling 2 who share the same biological mother but are unsure if they share the same biological father - in this situation, a full sibship test is conducted.
In the test, the DNA profiles of the siblings are compared to see how much of their DNA may have come from a common father. The mother's participation is recommended to help exclude the mother's contribution to the child's DNA.
