How long will it take for me to receive my Peace of Mind Sibling Test Results?

Results are completed within 2 to 3 business days from the date the lab receives all genetic samples. Once testing is complete, a copy of your results will be mailed to your home and another will be emailed to you.

Are Home Sibling DNA Test results accurate?

Yes. At-Home Sibling Testing is highly accurate because the laboratory compares specific genetic markers inherited from biological parents. When DNA samples are properly collected, stored, and submitted according to the test kit instructions, the laboratory can perform a reliable genetic comparison between the tested individuals.

Our partner laboratory typically analyzes up to 22 genetic markers during the paternity testing process to determine the probability of a biological relationship. In paternity inclusion cases, the probability of paternity is commonly reported as 99.99% or higher.

Are DNA results confidential?

Yes. Your DNA test results are kept confidential. Results are released only to the individuals directly involved with your paternity test. DNA results may be released by court order from or a judge but not before you are notified.

What is the difference between full and half sibling DNA testing?

The difference between a full sibling DNA test and a half sibling DNA test depends on which biological parents the two individuals are believed to share. A full sibling DNA test is performed when two individuals are believed to have the same biological mother and father. A half sibling DNA test is performed when they are believed to share only one biological parent, either the same mother or the same father.

To better understand the difference, a parent and child share approximately 50% of their DNA. Full siblings also share about 50% of their DNA because they inherit DNA from the same biological mother and father. In comparison, half siblings typically share about 25% of their DNA because they inherit DNA from only one shared biological parent.

Since half siblings share less DNA than full siblings, the laboratory's statistical analysis may be more challenging when only the two siblings are available for testing. In some cases, testing the shared biological parent can strengthen the analysis and improve the likelihood of obtaining a more conclusive result.

From your perspective, the testing process is the same. Both participants simply collect their DNA samples using the cheek swabs included in the at-home DNA test kit and return the samples to the laboratory for analysis.
