O36: Maternal care for other known or suspected fetal problems
O36.1: Maternal care for other isoimmunization
Blood is made up of blood plasma and different blood cells. The blood cells include red blood cells. They carry oxygen from the lungs throughout the body. In red blood cells there are particular characteristics. These characteristics are used as the basis for differentiating between blood groups. A distinction is drawn, for example, between blood groups A, B, AB and O.
When the mother and the unborn child have different blood groups, the maternal body can produce antibodies. The antibodies attack the child’s red blood cells. In certain cases these antibodies can get to the child and damage its red blood cells. This can create problems for the child.
