If you are in need of a Sibling DNA test. There are two options you can choose form depending on your specific situation.

Can a sibling DNA test be wrong?

It is possible for a DNA test to be wrong. Here are the scenarios in which we have encountered a DNA test being inaccurate.

1. Home DNA collection kits where the person who ordered the samples made an error with how they collected the samples.

2. When an embassy recognized physician collects the DNA sample of a beneficiary. Although a rare occurrence. It does happen from time to time that the lab will receive a sample that was incorrect in regards to labeling.

The reason we know this to be true is that we had the opportunity to re-test other DNA testing companies that offered our clients DNA test and their first test was incorrect.

3. Another scenario of a potential incorrect result is when a lab performs a DNA test on a small number of genetic markers (ex. 8 -12 markers). The DNA testing lab that performs our DNA tests utilizes a minimum of 18 markers or more if the DNA warrants more markers depending on the situation.

When will I receive my DNA Test result?

All DNA test results are mailed out to our client’s home, office or anywhere you deem private. For a more instant result, we also email a copy of the result to clients who have email addresses if requested.

Does my parent’s DNA sample need to be tested for the result to be accurate?

DNA testing for siblings can be performed accurately without a parent being involved. Although, having the non-common parent of one or both siblings involved can better help the laboratory determine which parent contributed their DNA to their offspring allowing the remaining 50% to be analyzed more efficiently against the other sibling.
