Aunt and uncle relationship testing

Avuncular DNA test cost in India

An avuncular DNA test examines whether an individual may be the biological aunt or uncle of a child. It is an indirect kinship test, considered when a possible parent is unavailable or cannot provide a sample and the parent’s sibling is available. The genetic question and family structure should be reviewed before collection. Depending on which parent’s side is being examined, additional relatives can change the interpretation. For an immigration, inheritance or court matter, ask for the formal collection route and take independent advice about requirements.

The important details, plainly stated.

Assesses a possible aunt–niece, aunt–nephew, uncle–niece or uncle–nephew link

A known parent or other close relatives may improve case design

Indirect testing cannot be treated as a direct paternity result

Legal or official use requires identity and sample-history documentation

When an avuncular test is considered

Families may ask about this option when the presumed parent is deceased, unreachable or unable to provide a sample. Explain which parent is being investigated and whether the proposed aunt or uncle is a full or half sibling of that parent.

Building a suitable comparison

The child and proposed aunt or uncle are the core participants, but an available known parent, grandparent or sibling may add useful context. The laboratory should confirm feasibility rather than relying on a generic participant list.

Official documentation

For formal proceedings, samples should be collected with verified identities and a traceable chain of custody. Requirements vary by authority, so a report cannot be promised acceptance before the receiving body reviews its format and procedure.

Questions patients ask

Before you decide

What is an avuncular DNA test?

An avuncular DNA test determines if a biological relationship exists between a child and an alleged aunt or uncle. It is used when the alleged parent is unavailable.

How is the avuncular DNA test performed?

DNA samples are collected via buccal swab or blood from the child and the alleged aunt/uncle. The samples are analyzed in a laboratory using STR markers.

What is the cost of the avuncular DNA test?

The cost is INR 24000, which includes home sample collection and the laboratory analysis.

How long does it take to get results?

Results are typically available within 10 days after the laboratory receives the samples.

Is fasting required before the test?

No, fasting is not required for this test.

What sample types are accepted?

We accept buccal swabs, blood in EDTA tubes, and blood on FTA cards.

Can the test be done for legal purposes?

Yes, but legal cases require a chain-of-custody process. Please inform our team if you need legal documentation.

Is home sample collection available?

Yes, we offer free home sample collection for online bookings across major cities in India.

What is the accuracy of the test?

The test is highly accurate, with a probability of relationship exceeding 99.9% for inclusion and less than 0.1% for exclusion.

Can the test distinguish between full and half siblings of the alleged parent?

No, the test cannot distinguish between full and half siblings. Additional testing may be needed in such cases.

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.

Grandparent DNA Test

The purpose of the Grandparent DNA Test is to establish a biological link between a grandparent and a grandchild. This can be needed for legal reasons (e.g., custody, inheritance), immigration applications, or personal peace of mind. The test helps clarify family relationships and can provide important medical history information.
