3 Types of Test
There are three types of Sibling DNA Test, depending on family make-up.
Full Sibling vs Half Sibling -‐ the test is designed to establish if two individuals share both parents or just one parent.
Half Sibling vs Unrelated -‐ the test is designed to establish if two individuals share one parent in common.
Full Sibling vs Unrelated -‐ the test is designed to establish if two individuals share both parent in common or no parents in common.
Once you place your order Rapid DNA Testing will work with you to establish the exact details. For instance with a Full Sibling vs Half Sibling Test, if it is known that two individuals share the same mother but they are unsure if they share the same father then it is important to advise Rapid DNA.
The Ordering Process
To start the process either order online or over the phone (866.873.0879). Rapid DNA Testing will send you a simple to use DNA collection kit. If participants are located in different parts of the US or World then Rapid DNA Testing can send a kit direct to each participant (please call to provide the details).
Once the samples are received your DNA Testing case manager will contact you to establish the exact type of sibling relationship to be tested.
Unique Testing Method: The Rapid DNA Testing Sibling DNA Test is the most advanced in the United States testing up to 41 DNA Markers.
Conclusive Range: We aim to achieve a 99.99% Yes or 0% No but this is not always possible and depends on how unique the participants DNA is and who can be tested. Results may show down to 80% yes or 15% No.
Turnaround Time: 5-10 Working Days
Participants: Two alleged full- or half-siblings, and any parent is optional, but strongly suggested. The probabilities can be increased greatly if other known relatives are available for testing.
Procedure: DNA samples are collected from two alleged (full or half) siblings at-home or at a DNA collection center (any parent is optional, but strongly suggested).
