Siblingship DNA Testing is used to determine if two or more individuals biologically share one or both parents. There are two types of DNA siblingship tests for which samples can be tested:

Full-Siblingship DNA Test
Half-Siblingship DNA Test
Full-Siblingship DNA testing involves two or more individuals potentially born of the same biological parents. Full siblings share much more of their DNA than individuals that are not related to one another. On average, full siblings have 50% of their DNA in common. Half-Siblingship DNA testing involves two or more individuals who potentially share only one biological parent. Half siblings generally have 25% of their DNA in common. When the issue of siblingship is in question, the recommended method to determine whether individuals are true biological siblings is to test them and their alleged parent(s). In situations where the alleged parents are unavailable for testing, a DNA siblingship test can be performed by testing only the samples from the alleged siblings. Including at least one alleged common parent greatly increases the accuracy of the analysis and is recommended, if at all possible. To order a Siblingship DNA Test click here
General Procedure
Call our DNA specialists at toll free 800-DNA-EXAM/888-786-9323 or write to us to initiate a Siblingship DNA Test. DNA samples may be collected from two or more alleged (full or half) siblings at home (using our BIOSWABTM DNA Sample Collection Kit) or at one of our DNA collection sites across the U.S. Parents' samples are strongly recommended. The samples are obtained using a buccal swab (provided by our laboratory). After samples are checked in to our laboratory, results will be available within 5-7 business days.
