Sibling DNA testing is used to confirm or deny relationships between siblings. There are many benefits to sibling DNA testing like providing certainty to parents who are unsure about their child's paternity. It can also help siblings resolve disputes about their parentage.
A sibling DNA test helps determine if two individuals share the same two parents or one common parent. Full-sibling and half-sibling DNA tests are the two types of sibling DNA tests that exist. The process requires a simple cheek swab of the concerned individuals.
The testing process for sibling DNA tests is quite straightforward. A sample of DNA is taken from each sibling with the help of cheek swabs and sent to our laboratory for analysis. The test looks for specific markers in the DNA that are unique to each individual. The results are available within 5 business days.
