Most blood types are determined by the combination of three genetic factors such as A, B, and O. In most cases, one can predict the possible blood type of a future child based on the blood types of the parents. Based on your blood type and that of your immediate relatives, it can be determined whether your child's blood type might be A, B, AB, or O. Therefore, there is no need to worry about mistakenly adopting a child. If you still have concerns, you can opt for a comprehensive paternity test.
