Question
If both parents have A-type blood and the child has O-type RH anti-D positive, what does this mean?
Answer
Parents with A-type blood can indeed have a child with O-type blood. Blood types are categorized into ABO and RH types. In the Han population, most people are RH positive. In daily life, we commonly use the ABO blood typing system, so you may not be familiar with the RH factor. In this case, the child’s blood type is not abnormal, and you can rest assured. If there are future plans for childbirth, regular check-ups should be scheduled, particularly focusing on hemolytic series situations. Since O-type blood mothers have a higher likelihood of their children experiencing ABO hemolysis, although the chance of this occurring is relatively small.
