A Sibling DNA Test Determines Full Sibling – Half Sibling – No Relations!
We offer precise sibling tests (Up To 35 Markers) from trusted USA lab.
What Is A Sibling DNA Test?
Sibling DNA testing analyzes the DNA of alleged brothers or sisters to determine if full siblings, half siblings or not related. A brother and sister DNA test can help prove or disprove the paternity or maternity indirectly. DNA testing for paternity through siblings is the best option when the alleged father or mother is unwilling or unavailable to be tested. Our DNA test for siblings can analyze Up To 35 Markers, which is almost 50% more markers than our competitor’s 24 marker test.
Furthermore, our sibling DNA test is the best solution to confirm or deny Ancestry.com ®, 23andMe.com ®, or MyHeritage.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 Sibling Tests Results Prove?
Our 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.
If no known parent(s) can be added to the DNA test, you may consider the option to analyze additional DNA markers(Up To 35) to ensure you get the most conclusive answer possible.

Can you test types of genetic samples?
YES, ear wax, finger or toe nail clippings, hair (w/ root ball), mucous on a tissue, and toothbrushes are common forensic DNA samples. For more information & pricing please call us at toll free (877) 786-9543.
10 COMMON SIBLING TEST QUESTIONS:
YES, a sibling DNA test can conclusively determine you’re a full or half sibling thus proving or disproving paternity.
No, in-fact unless the individuals are identical twins all siblings have unique genetic profiles. The combination of genetic markers inherited from both parents makes every brother or sister unique.
When testing brothers for paternity, a Y-STR test is a good option to consider. The Y-STR male line DNA test compares the unique Y-Chromosome (Like A Fingerprint) every father passes to his male child. A Y-STR analysis will always produce a conclusive “Yes” or “No” as to whether or not the alleged male sibling comes from the same male line.
Likewise, an mtDNA female lineage test provides a conclusive answer regarding a relationship on the maternal side.
When someone wants to see if they are a sibling or a cousin, a sibling DNA test may not produce the most conclusive result. Therefore, we recommend a paternity or maternity test with the parent in question as the best solution. Call us at (877) 786-9543, and we can help guide you to the best DNA test.
YES! However, our mission is to first provide the most reliable & accurate results at the cheapest prices, and as quickly as possible.
Some promise one day results, but in reading the fine print, their disclaimer says it can take 3-5 days.
Having said that, we do offer a 1-day processing option if at least 1 mom is included in the test. (Please call to request 1-day service option)
Sometimes you have to do the DNA collection right away or lose the opportunity to obtain a sample. In such cases, you can use regular Q-tips for the collection, however this is not ideal. For this reason, PaternityUSA will rush a medically sealed sterile kit to you FREE.
YES, commonly used forensic DNA samples include ear wax, hair (must have the root ball attached), mucous on a tissue, finger or toe nail clippings, and toothbrushes. Please contact us at (877) 786-9543 for more info.
