Sibling DNA Testing

Sibling Testing is a DNA test process that is performed to determine if two people share one or both parents. For example to determine if they are full or half siblings. This is an indirect method to prove family relationships when the alleged father is not able to perform a paternity test.

Test Me DNA offers Sibling DNA Testing nationwide. One low price of $179 includes everything required for Sibling DNA test results.

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.

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

If 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.
