These days we can do so many things from the comfort of our home, so why not a DNA test as well? Absolute DNA Services has streamlined the process for the Sibling Test, so it’s as easy as:
The results of this test are achieved through a ‘siblingship index.’
If the index is higher than 1.00, this is an indication that the tested individuals are likely to be either full or half siblings. If the index is lower than 1.00, the results will reveal that there is no relation between the tested parties.
Male siblings who want to know if they have the same biological father are encouraged to take a Y Chromosome Test, which provides highly accurate results.
Female siblings who want to know if they have the same biological father are encouraged to take an X Chromosome Test (requires an additional sample from the mother).
