An STR analysis sibling test is done to establish whether brother and sister share a common parent. The test will clearly map the DNA profiles of each party so that they can then be compared. In an STR analysis test (Short Tandem Repeat) - our analysts will see how different the repeats of DNA sequences are between the tested people. True siblings will have a number of repeats of on their DNA which are shared between them. The test is used to determine whether siblings share both (full siblings), one parent (half siblings) or are not related at all.
Determining the biological relationship between siblings relies on statistical probability which will establish the most viable relationship given the results obtained. Therefore, where possible, we recommend sending in an available parent’s DNA sample so as to be able to establish their share in the genetic inheritance and increase the strength of the results we provide.
