What Is Sibling DNA Testing and How Does It Work?

-


 
Can a DNA test prove half or full siblings? Do half-siblings share enough DNA for a DNA test? Will the results be accurate? If these questions remain recurring, you might consider sibling DNA testing. Siblingship DNA tests in India are provided to determine the statistical probability of whether or not two or more individuals are full or half siblings.

Types of Sibling DNA Testing

There are cases when it's unclear whether two siblings share the same biological parents or not. In such a case, a Sibling ship DNA test can come to aid. Depending upon the issue where either of the biological parent's identity is known or unknown, you can get the following types of Sibling ship DNA Tests in India, or anywhere else, for that matter.

  • Full Sibling DNA Testing: In this test, the DNA of both individuals are compared to determine the likelihood of whether they share the same biological parents.
  • Half-Sibling DNA Testing: This test is ideal for cases where alleged siblings share common biological parents but are unaware of which one.

Sample Collection

The process of Sibling DNA testing starts with collecting samples from both parties. These samples are then sent to the analysis lab where DNA profiling and report generation take place. Typically, samples are collected using buccal swabs, which are rubbed on the inside of the cheek to collect cheek cells. After that, we gather the collected epithelial cells and extract the DNA for analysis.

Factors to Consider When Selecting a Sibling DNA Test?

At-Home Sibling DNA Test:

An at-home sibling DNA test, also known as a Peace of Mind DNA test, is conducted for personal information only. The identities of the individuals involved are not legally verified. The test provides peace of mind, and a pre-paid express envelope is provided to send the DNA samples to the lab.

Siblingship Index:

A sibling DNA testing report provides a 'Siblingship Index.' Unlike other relationship DNA tests, the report measures how much DNA matches between two DNA profiles. If the Siblingship Index is less than 1.00, the alleged siblings are not genetically related. If it is greater than 1.00, it indicates a biological relationship.

Applications of Siblingship DNA Tests in India

Following are some applications of Sibling DNA testing:

  1. Peace of Mind (POM) - Peace of Mind Sibling DNA Testing is used when two alleged siblings want to determine if they are biologically related.
  2. Legal Matters—A legal siblingship DNA test establishes an individual's parenthood in court cases involving child support or custody, social security, and other legal matters.
  3. Immigration Purposes - In immigration cases, when a person sponsoring their siblings' immigration/visa requires proof of sibling relationships, DNA tests are needed to avoid visa refusals.
  4. Organ Transplant - According to THOA, 2014, sibling DNA testing for an organ transplant is necessary if the involved parties are brothers or sisters.
