Frequently Asked Questions
How long does a home brother and sister DNA test take to receive results?
The turnaround time for results is two to three business days from the date the lab receives all DNA samples.
Upon completion of your results, your assigned DNA caseworker will contact you to provide a verbal update on the status of your results. A copy of your results will be sent to you by physical mail, and an additional copy will be sent to you by email. .
Are home sibling DNA tests accurate?
Yes. Home sibling DNA tests can provide highly accurate statistical evidence of a biological sibling relationship when the DNA samples are properly collected and submitted to the laboratory.
Three common factors that can affect the quality of a DNA sample are:
- How well the samples are stored.
- The effectiveness of the DNA sample collection.
- Sample contamination or tampering.
Poor-quality DNA samples can make laboratory analysis more difficult and may require a new sample to be collected.
When sufficient DNA is available for testing, the laboratory compares the participants’ genetic markers and calculates the statistical probability of a biological sibling relationship. The results may support a full-sibling or half-sibling relationship, exclude the tested relationship, or in some cases be inconclusive..
Can my sibling DNA results be used for legal purposes?
No. Home sibling DNA tests are for informational use only and cannot be used legally.
Can DNA testing be performed if both parties live in two different cities?
Yes. A DNA test kit can be shipped to two different locations.
What is the difference between a Home Sibling DNA Test and a Legal Sibling DNA Test?
A Home Sibling DNA Test is a non-legal testing option used for informational purposes only. This option does not require an established chain of custody, which is necessary for a Legal Sibling Test.
A Legal Sibling Test requires an established chain of custody and DNA sample collection by an unbiased third-party collector. All DNA samples are tested and analyzed by our partner AABB-accredited laboratory.
Will my information be kept private?
Your information will remain private. The lab does not share data collected for DNA analysis with third-party companies. DNA samples are stored for an average of three months before destruction. Data may be shared only by court order but not before the client is notified.
