Indirect parentage testing

Grandparent DNA test cost and options

A grandparent DNA test uses the genetic profile of one or both grandparents to assess a possible biological connection with a grandchild, often when the alleged parent cannot participate. It is an indirect relationship assessment and should be planned around the exact family question. Including the child’s other known parent, the second grandparent or additional relatives may help distinguish competing relationship hypotheses. Ask for a case-specific participant plan and quote rather than treating a general price as a promise of suitability or outcome.

At a glance

The important details, plainly stated.

Useful when a presumed parent is unavailable or cannot be tested

Testing both grandparents may provide more family information than one

Additional known relatives can be considered after case review

Legal cases need documented consent, identity and chain of custody

Understanding the indirect question

The report assesses genetic compatibility between the grandparent group and child; it does not directly test the absent parent. Tell the laboratory whether the proposed parent is the grandparent’s biological child and which family members are known.

Selecting participants

One or both grandparents, the child and an available known parent may be considered. The best design depends on family structure and the question being asked. Do not assume that adding a relative is necessary or sufficient without professional guidance.

Results and decisions

A statistical relationship assessment should be read with its stated assumptions and limitations. It cannot determine custody, inheritance or citizenship on its own. Obtain legal advice if the report will support an official application or dispute.

Sibling DNA Test

The primary purpose of a Sibling DNA Test is to establish the biological relationship between siblings. This may be needed for legal reasons (e.g., inheritance claims, child custody), immigration applications, or personal curiosity. The test provides conclusive evidence of whether individuals share the same biological parents, helping to resolve doubts and provide clarity.

Avuncular (Aunt/Uncle) DNA Test

The primary purpose of the avuncular DNA test is to establish or exclude a biological relationship between a child and an alleged aunt or uncle. This is often necessary when the alleged father is deceased, absent, or unwilling to participate in a paternity test. The test can also be used to confirm kinship for legal matters such as inheritance, child custody, or immigration. By analyzing genetic markers inherited from common ancestors, the test provides a statistical likelihood of the relationship, helping families and legal authorities make informed decisions.

Legal Paternity DNA Test

The purpose of a Legal Paternity DNA Test is to provide scientifically conclusive evidence of biological fatherhood that is admissible in a court of law. It is used to resolve legal disputes involving inheritance, child custody, maintenance, immigration, and birth certificate corrections. The test follows a strict chain of custody to ensure that the samples are collected, transported, and analyzed without any tampering, thereby guaranteeing the integrity of the results.
