Frequently Asked Questions
How accurate is a sibling test?
Our sibling DNA tests deliver 99% accuracy through our partner AABB accredited laboratory.
Understanding your results:
We provide probability percentages, not yes/no answers. Probabilities above 90% strongly indicate biological relationships. Probabilities below 10% suggest no biological relation.
Accuracy depends on relationship type:
- Full siblings share 50% of genes
- Half-siblings share 25% of genes
- Half-sibling analysis requires additional statistical evaluation
Testing Accuracy:
- Include additional family members when possible
- Use standard cheek swabs for best results
- Forensic samples (hair, toothbrush, clothing) may compromise accuracy due to DNA degradation
Important note: Sibling testing uses statistical probability analysis rather than the direct comparison methods used in paternity testing. Our partner accredited laboratory ensures reliable probability assessments that accurately determine sibling relationships.
Can you do a sibling DNA test without the father in NJ?
Yes. Sibling DNA tests are performed without the father. In cases when the father is available to participate in the DNA testing process performing a paternity test is a recommended testing option.
Can sibling DNA test results be used for legal purposes in New Jersey?
Yes. DNA sibling tests can be used for legal purposes if you have performed a legal sibling test.
Non-legal Home Sibling DNA test results are for informational use only and do not meet the requirements for legal evidence submission in New Jersey.
Can you determine paternity through siblings?
Yes. Both paternity and maternity can be determined by performing a sibling DNA test. Please keep in mind that sibling Ancestry tests by companies like 23andMe are tested differently and their results cannot be used for legal purposes.
Do brothers and sisters have the same DNA?
Brothers and sisters do not have exactly the same DNA, but they do share a significant amount. On average, full siblings (who have the same biological parents) share about 50% of their DNA. However, the actual amount can vary somewhat due to the random nature of genetic inheritance – it could range from roughly 40% to 60%.
Each parent contributes half of their genetic material to each child, but which specific genes get passed down is random. This is why siblings can look quite different from each other despite having the same parents.
The only siblings who would have identical DNA are identical twins, who develop from the same fertilized embryo.
