Sibling DNA Test

Service Description

A siblingship DNA test is used to determine whether two individuals share one or both biological parents. This test calculates the probability of a full or half-sibling relationship based on their genetic profiles. In cases where both individuals share the same biological mother, the test can help determine the likelihood that they also share the same biological father. Whenever possible, we recommend including the mother's DNA sample as well. This helps us identify which genetic markers were inherited from the mother and which were passed down by the father, significantly increasing the accuracy of the results. We can also perform siblingship tests for individuals with different mothers to assess whether they may share a biological father.
