Patient's question:
The second baby was born half a month ago (a girl, the first child is O-negative). The local maternal and child health hospital, based on the blood test report, speculated that the baby is A-positive, the mother is O-negative, and the father is B-positive. Is this speculation about the baby's blood type accurate? Will there be any risk of hemolysis again?Doctor's answer:
In your case, if you have doubts about the blood type, you can get a retest for it. Generally, the chance of a baby having type A blood with an O-type mother and a B-type father is very, very low.1. Suggest getting a retest for the blood type.
2. Generally, if the mother is O-type and the father is B-type, the baby's blood type is usually either O-type or B-type.
There have been reports of a blood type called the Bombay blood type, which appears as O-type but is actually a false O-type. Babies born to such mothers may have type A blood.
