No.. I don't know why, but you cant. You would need a fingerprint, or skin, or hair, or even a semen sample to test for that to make sure. Blood Sample can only prove who is not your father.'Hope that helped.

no, of course not. one of the two allele that make up your blood type is coming from your dad, and the other from your mom. so your blood type would be the combination of four alleles coming from your parents and can be different from both of them.
