Patient's question:
A while ago, I found out I was pregnant, and my husband and I were both very happy. We are looking forward to this child very much! Recently, I read an article saying that the child might have hemolytic disease. Both my husband and I have type O blood. I don't know what blood type our child will have, and I'm also very worried about the situation mentioned in the article.What kind of blood type will a child have if both parents are type O?
Doctor's answer:
Two O-negative blood type couples will have a child who is also likely to be O-negative, and not any other blood type.
