Sibling DNA Relationship Testing
Sibling DNA Testing is a DNA test process that is performed to determine if two or more people share one or both parents. For example to determine if they are full or half siblings. Sibling DNA tests are typically used as an indirect method to prove family relationships when the alleged father is not able to perform a paternity test. However, in rare cases, sibling tests are used to determine if 2 people share the same mother.
With all relationship testing, the mother of the child is always urged to test. This allows less of a chance to receive inconclusive results. If the biological mother is not available, the test can still be performed. Additional undisputed siblings can also be added to provide a stronger test result.

How Sibling DNA Testing Works
Order Sibling DNA Test
After deciding on a test, we will either send out a Home Sibling DNA Test Kit or schedule an appointment for Sibling DNA Testing at any of our 1000+ Testing Centers for DNA collection.
DNA collection is painless and easy to perform. DNA collections are performed with non-invasive buccal swabs. The swabs are brushed lightly on the inside of each individual’s cheeks for around 10 seconds.
Get Sibling DNA Results
Results typically complete within 3-10 days after the laboratory receives all testing kits. Sibling test results are then provided over the phone and email. Mailed copies can be sent upon request.
Full Sibling vs Half Sibling DNA Testing
When two siblings share the same mother and want to learn if they share the same biological father a full sibling DNA test would be performed. If the test confirms the biological father of the siblings they would be full siblings.
The full sibling test can only be used if two siblings share the same mother.
Half Sibling vs Not Related DNA Testing
When two siblings do not share the same biological mother but want to learn if they share the same biological father.
The half sibling test can be performed with or without the mothers involved. Adding a mother to testing is always encouraged for more conclusive and accurate results.
