In today’s world, DNA testing has become a powerful tool for determining biological relationships. While most people know about paternity or maternity DNA tests, there’s another important category – Sibling DNA Testing. Whether you’re verifying biological relationships or need evidence for legal or immigration purposes, a sibling DNA test can provide the answers. This guide will help you understand what sibling testing is, when and why it’s needed, and how accurate it is.
What is a Sibling DNA Test?
Sibling DNA test is a kind of genetic test used to determine whether two or more individuals are biologically related as siblings. It helps to confirm if they share one or both biological parents.
There are mainly two types of sibling relationships that the test looks at:
- Full siblings – Share both biological parents.
- Half-siblings – Share only one biological parent (either mother or father).
Sometimes, it’s not feasible to conduct a paternity/maternity test due to the absence of the parent. In such matters, a sibling DNA test can offer strong supporting evidence about shared parentage.
Why Choose It?
There are various personal, legal, & emotional reasons why an individual may opt for this test. Following are the most common ones:
-
Peace of Mind
Sometimes, people grow up with doubts about their biological family—especially in cases of adoption or unknown parentage. A sibling DNA test can offer clarity and emotional closure.
-
Immigration Purposes
In many countries, including the UK and Australia, immigration authorities may ask for DNA proof to verify biological relationships during immigration applications. If siblings are applying to reunite with each other, a sibling DNA test can act as a robust piece of evidence.
-
Family Reunification or Adoption
People who are adopted or separated at birth may want to confirm whether someone is actually their sibling. This test becomes crucial for those trying to reunite with biological family members.
-
Legal Matters
When parents are not available and queries of inheritance or property division arise, confirming sibling relationships may be essential. Honourable courts in India may request this test to determine rightful heirs.
How Does the Test Work?
The method of a sibling DNA test is relatively straightforward. Here’s how it typically works:
-
Sample Collection
- DNA is collected using a simple buccal swab. Buccal swabs are rubbed inside the cheek walls to collect epithelial cells.
- This procedure is painless and takes only a few minutes.
- Samples can be collected at home or in a certified DNA collection center.
-
Laboratory Analysis
- The samples are sent to a laboratory where scientists examine DNA to determine the likelihood of a biological relationship.
- The lab calculates a sibling index, which indicates the probability that the individuals tested are biologically related as siblings. A higher sibling index suggests a stronger possibility of a sibling relationship.
-
Test Reports
- You will receive a report that tests within 4-5 working days. DNA Forensics Laboratory Pvt. Ltd. also offers express service (getting reports in 1-2 days). For legal DNA testing, it might take more days due to formalities and courier timelines.
Legal and Non-Legal Testing
There are two forms of sibling DNA test:
-
Peace of Mind Test
- Done secretly just to get clarity about connections.
- You can collect the DNA samples yourself at your home.
- The reports are not valid for legal cases, but can offer emotional clarity.
-
Legal DNA Testing
- Used for court cases, immigration, inheritance, etc.
- Sample collection is done under strict guidelines with identity verification.
- Chain of custody is maintained.
- The report is admissible in courts or government agencies.
How Much Does a Sibling DNA Test Cost?
The price of a sibling DNA test varies based on the following factors:
- Number of people tested.
- Legal vs. non-legal testing.
- Express DNA testing services.
The average cost ranges from 22,000 INR to 25,000 INR* for two siblings. Legal tests may be slightly higher due to verification processes and paperwork.
*Prices may vary based on location & testing complexity.
