An Insight into Sibling DNA Testing

Sibling DNA testing plays a crucial role in establishing biological connections between individuals who share common parents. This type of test examines the genetic material, specifically DNA, to establish if two individuals are indeed siblings.

The Science behind Sibling DNA Testing

At PaternityUSA, our advanced diagnostic services employ a variety of techniques, such as STR (Short Tandem Repeat) testing, to examine DNA samples in order to determine sibling relationships. STR testing analyzes specific regions of DNA where variations in the number of repeats occur. By comparing these regions across two individuals' DNA profiles, our experts can assess the likelihood of a sibling relationship.
