Question
Can two O-type blood individuals have a child with A-type blood? My husband and I are both O-type, can our child be A-type? Have we received any treatment in the past, and what were the results? We hope to receive the doctor’s assistance quickly and understand how to treat and prevent this.
Answer
Generally speaking, if both parents are O-type blood, their child will only be O-type. Blood type is determined by Intergenerational transmission , so two O-type blood parents cannot have an A-type blood child. However, in some cases, there may be a testing error. If a child’s blood type is tested as A-type, it could be a mistake or the child might have been raised by someone else. It is recommended to conduct multiple thorough checks to confirm the blood type.
