Normal value of hemolytic antibody titer

Hemolytic disease is a very harmful symptom that causes very dangerous damage to people's health. Among them, women have the highest probability of suffering from hemolytic disease, especially postpartum women. This disease can be prevented. The most effective preventive measure is to inject hemolytic antibodies to gain resistance. However, this antibody will only be effective when it reaches a certain value. Let’s take a look at the normal value of hemolytic antibody titer.

What is the normal value of ABO hemolysis?

ABO hemolytic disease is a neonatal hemolytic disease caused by ABO blood type incompatibility between mother and child. It is a type of isoimmune hemolytic disease. Most of the cases of neonatal hemolytic disease in my country are ABO hemolytic disease.

Antibody test time: the first time is at 16 weeks of pregnancy, the second time is at 28-30 weeks of pregnancy, and then every 2-4 weeks. The normal value of ABO blood incompatibility antibody titer is less than 1:64. If it is 1:64, no attention or treatment is needed. At 1:128, the fetus may develop hemolytic disease, which can be treated with Artemisia Capillaris decoction, which has a certain effect on preventing premature birth, miscarriage, and hemolysis. If the antibody effect continues to increase, comprehensive treatment can be given at 30-32 weeks of pregnancy, including oxygen inhalation, intravenous injection of glucose and vitamin C, etc. However, when the ratio is above 1:512, it indicates a serious condition and an amniotic fluid examination should be performed or termination of pregnancy should be considered in combination with the past history of adverse delivery.

What is the normal value of hemolysis in newborns?

There are four types in the ABO blood type system: "A", "B", "AB" and "O". ABO blood type incompatibility hemolytic disease mainly occurs when the mother is "O" type and the fetus is "A" or "B" type. The highest normal bilirubin level in newborns is about 51.3 μmol/l (3 mg/dl)

Jaundice in most newborn babies is physiological, harmless to the baby, and is a normal phenomenon of physiological development. Physiological jaundice usually appears 2 to 3 days after birth and reaches its peak on the 4th to 5th day. This type of jaundice is not accompanied by any disease and will return to normal in about 7 to 10 days as the liver matures. In premature babies, it will last for a few more days. Parents just need to give their babies enough water.
