The idea
When a parent is unavailable, a kinship test compares other relatives — siblings, grandparents, aunts or uncles — to assess whether the claimed relationship is supported.
What the result looks like
Kinship results are probabilistic. The further apart the relationship, the more the conclusion is expressed as support for or against the claim rather than a near-definitive answer. Adding relatives usually sharpens the interpretation.
Planning the comparison
A coordinator reviews who is available and recommends the combination with the most statistical value — for example, including a known grandparent alongside two possible siblings.
