Siblingship DNA Testing


I am not sure if my two kids share the same father, but I can’t share this doubt with anybody, especially not with my father.

Is there a DNA test that could help me to find the answer?

A sibling test provides the probability of a genetic relationship between two people to tell if they share the same father. This test could be done even if the kids don’t share the same mother.

A full siblingship test can determine if the two subjects share the same mother or father. You could expect results within 5 days from the reception of the samples. A siblingship test can be performed even if the mother is not available for testing.  However, the mother's participation is always encouraged for more conclusive results. 

Results will show a Combined Siblingship Index, a statistical value showing the genetic odds in favor of the relationship. This number represents the number of times that the tested individuals are more likely than not to be biologically related as siblings.
the same principle applies for the A half-sibling test
