Higher indirect bilirubin and normal liver function may be caused by physiological reasons such as neonatal jaundice or pathological reasons such as hemolytic jaundice. 1. Physiological reasons: newborns will have temporary elevation of indirect bilirubin, which is a normal physiological phenomenon, usually after 2 weeks, the jaundice will subside and the indirect bilirubin will be lowered, so there is no need to worry too much. 2. Pathological reasons: when blood transfusion, the blood type does not match, there may be hemolysis, resulting in a large number of red blood cells in the body is destroyed, can not be converted in time, the hemoglobin in the red blood cells are released into the blood, which will cause the indirect bilirubin to rise. In addition to this, severe burns, pernicious anemia, sepsis, etc. can also lead to elevated indirect bilirubin, but liver function is normal. In case of elevated indirect bilirubin, the cause should be identified promptly and standardized treatment should be carried out under the guidance of a doctor.
