To determine a biological sibling or half-sibling relationship.

What is a DNA sibling test?

Siblings are brothers and/or sisters.

Full-siblings have the same mother and father, while half-siblings share only one parent.

A sibling test can be used to confirm whether two, or more children are related and to identify if they share one or both biological parents.

There are many reasons for doing a DNA siblingship test and NOVAGEN offers the latest technology and accurate testing to resolve questions about biological-sibling relationships.

How conclusive is a DNA sibling test?

Sibling analysis is not as conclusive as paternity testing and can only report the most likely relationship ‘given the DNA evidence’.

The results will provide a statistical likelihood of whether two individuals are true biological relatives, but sibling analysis cannot provide a conclusive result. However, if either of the parents of the siblings who are being assessed are available for testing, this will aid the analysis and may increase the certainty of the result.

When set up as a legal case, results from a sibling DNA test can be used for inheritance benefits, proof of relationship for immigration, and more.

Reasons to get a Sibling DNA Test

The most common reason for taking a sibling DNA test is to confirm the truth about whether you and your sibling share the same father. Other reasons to take the test are:

Medical history
Social Security benefits
Inheritance claims
Immigration cases
Insurance claims

Results are completely confidential, and your private genetic information is never shared with or sold to outside parties.

Testing Options for Sibling DNA Testing

There are two main options for doing a sibling DNA test: legal or for personal knowledge.

Legal:

Legal test results for siblings can be submitted to court as legal proof of a biological relationship. NOVAGEN coordinates DNA-sample collection at an approved location near you. The professional collector then compiles all identification, completes paperwork for the test, and sends the package to NOVAGEN for testing.

Personal Knowledge:

If you need the sibling-test results solely for peace of mind and not for legal reasons, you have the option to collect your samples at home with the sibling DNA test kit and then send them to NOVAGEN for testing. Keep in mind results are not court admissible.
