A hemolytic anti-A value of 1:2048 is considered a more serious condition. Anti A potency is a test that evaluates the likelihood of ABO hemolytic disease in newborns. An anti-A value greater than 1:64 is considered abnormal, and an anti-A value of 1:1256 is considered dangerous, as the child is likely to develop ABO hemolytic disease of the newborn, and the mother is likely to develop coagulation disorders. If the anti-A antibody is 1:2048, it is a very dangerous condition, and the fetus is highly suspected of hemolysis, jaundice, preterm delivery, or stillbirth. Most cases of ABO hemolytic disease are caused by the incompatibility of the blood groups of the mother and the baby, mainly when the mother is type “O” and the fetus is type “A” or “B”. Because the anti-A or anti-B IgG of O-type people is more than that of A-type and B-type people, and the antigen of A antigen is stronger than that of B antigen, therefore, there are more chances for those whose mothers are O-type and their fetuses are A-type to get the disease. If you have hemolytic anti-A abnormality, you need to go to the hospital as soon as possible, the doctor according to the specific conditions, to formulate individualized diagnosis and treatment plan, so as not to delay the condition.
