When relationship testing is used
Relationship testing evaluates whether two people are biologically related in a specific way. It is commonly used when a parent is unavailable, deceased, or unwilling to participate, or when a family relationship must be supported for immigration or estate purposes.
Common test types
- Sibling testing — full, half, or unrelated
- Grandparent testing — supporting a parental link through a grandparent
- Avuncular testing — aunt or uncle to niece or nephew
- Y-chromosome testing — a shared paternal line between males
Understanding the results
Relationship results are reported as statistical likelihoods rather than simple inclusion or exclusion. Including additional relatives, such as a known biological parent, usually strengthens the analysis. The laboratory partner interprets the data according to accredited procedures.
Getting the right test
