What Is A Sibling DNA Test?

Our affordable sibling DNA testing analyzes the DNA of alleged brothers or sisters to determine if they are full siblings, half siblings or not related.  This brother and sister DNA test can help prove or disprove paternity or maternity indirectly. DNA testing with siblings is the best testing option when the alleged father or mother is unwilling or unavailable to be tested. Our premium at home DNA test for siblings will analyze 46 Markers, which is 2X more markers than competitors' 20-22 markers.

Furthermore, our sibling DNA test is the best solution to confirm or deny Ancestry.com ®, 23andMe.com ®, or My Heritage.com's ® genealogy test results. These heritage & ancestry kits use a database to indicate that you may have found a lost brother or sister, but most importantly we can prove or disprove the findings.

What Will The Siblingship DNA Testing Results Prove?

The results will show if the participants are full siblings (both parents in common), half siblings (one parent in common) or not related as brother and sister. This is accomplished by actually comparing one person against another, and not just by using an ancestry or heritage database.

Full Siblings - Half Siblings - Not Sure If Related

A full sibling test assumes there is one known parent in common and tests to conclusively determine if both parents are shared.

A half sibling test assumes one parent is different and will determine if one or no parent is shared.

A test for both full and half sibling will let you know whether one, both, or no parents are shared. If you are not sure whether the mother and or father are shared, performing both a full and half sibling DNA test gives the most complete picture of the relationship. Our precise results may provide the adoption answers you seek from a lab you can trust.

How accurate is DNA testing for siblings?

Sibling DNA testing is 100% accurate and can produce very conclusive results.  Generally,  the analysis can be performed with only two or more brothers or sisters, however we recommend adding any available known parent(s) to help increase conclusiveness.  Please feel free to call us at (877) 786-9543 for consultation.

In certain situations, if no known parent(s) can be added to the DNA test, you may consider the option to analyze additional DNA markers (Up To 46) to ensure you get the most conclusive answer possible.
