A Sibling DNA Test is a genetic test used to determine whether two or more individuals are biologically related as full siblings, half-siblings, or not related at all. This type of test is often used when the alleged parents are unavailable for testing, but individuals want to establish a biological connection.

                              Here’s a clear and professional description of a Sibling DNA Test

 Sample Collection
A simple and painless cheek swab is collected from each sibling. If available, adding a known parent (usually the mother) can increase the accuracy of the results.

  1. Laboratory Analysis
    The DNA from each participant is compared to identify shared genetic markers. The number and pattern of these markers help determine the likelihood of a sibling relationship.

  2. Results
    Results typically indicate one of the following:

    • Full Siblings (same biological mother and father)

    • Half Siblings (one biological parent in common)

    • Unrelated (no significant biological relationship)
