Full/Half Sibling DNA TestingFull-siblingship exists if two or more individuals have the same biological parents. These services can be ordered either for personal purposes or legal purposes.
Procedure:
DNA samples are collected from two alleged (full or half) siblings at home for personal information. It is strongly suggested that any known parent of the two alleged siblings be included in the test as his or her genetic information is helpful in verifying the possible relationship between the siblings. (there are no additional fees for the parent(s). The results for a full-siblingship test with the involvement of one or both biological parents will produce a high probability of full-siblingship, often above 90%.
You may receive results that are given in probability of full-siblingship or probability of half-siblingship. Unlike paternity tests, this probability will not provide overwhelming certainty of a biological relationship. Rather, this probability will show whether the siblings are more or less related.
