Abnormal liver function in newborns mainly depends on the following indicators: first, you can look at glutathione and glutamic oxalacetic aminotransferase, because the sensitive indicators that cause abnormal liver function mainly refer to these two, if these two are more than twice the normal value, most of them are due to pathological reasons and need timely liver protection treatment. Second, look at the bilirubin level in the blood, which includes both conjugated and unconjugated bilirubin levels. If the unconjugated bilirubin level is significantly high, it is mostly due to hemolysis. Finally, we can look at the alkaline phosphatase in the liver function. Alkaline phosphatase can obviously reflect the degree of cholestasis, and high alkaline phosphatase is often caused by cholestasis, which requires cholestasis treatment.
