Question

Can individuals with O-type blood donate blood to a B-type spouse? What tests are required? What is the incidence rate of neonatal hemolytic disease?

Answer

O-type blood is known as the “universal donor” and can be transfused to individuals of other blood types in emergencies. However, when donating to a B-type recipient, a cross-matching test must be conducted to avoid potential blood clotting reactions. Generally, the amount of blood transfused should be kept within a safe range. Regarding the incidence rate of neonatal hemolytic disease, if the mother is O-type and the father is B-type, the child has a potential risk of neonatal hemolytic disease. In such cases, the mother should undergo relevant tests during pregnancy and closely monitor the newborn after birth to determine if the disease is present. If the child is diagnosed with hemolytic disease, immediate medical assistance should be sought, and follow the doctor’s treatment recommendations. Treatment typically includes exchange transfusion therapy and other protective measures to protect the baby and alleviate symptoms. It is important to note that cross-matching tests are a crucial procedure to ensure blood transfusion safety. In most cases, only a small amount of blood needs to be transfused, and it should only be done when necessary. If a large amount of blood needs to be transfused, it is best to use B-type blood to avoid unnecessary risks. For neonatal hemolytic disease, mothers should take their child to a doctor for immediate treatment and avoid self-administering any medication not prescribed by a doctor. Proper medication use is very important during the treatment process, and parents should provide adequate care and attention to help the child recover as quickly as possible.
