The function of liver function test for babies over 8 months old is to find out whether the transaminases, bilirubin, albumin, etc. are at normal levels and so on. If the baby is more than 8 months old, jaundice may occur, then the liver function test can understand the bilirubin increase situation and clarify the severity of jaundice. In the course of jaundice treatment, blood is also needed to check liver function, which can help to find out how bilirubin decreases and clarify the effect of treatment. If your 8-month-old baby has pathologic jaundice, you also need to know if the high bilirubin is caused by hepatitis. Liver function tests can clarify the cause and severity of liver function damage, and can also assist in the diagnosis of cholestasis, biliary obstruction, and other damage to liver function. The presence of infectious diseases in 8-month-old babies can also lead to impaired liver function, and then also need to check the liver function of aminotransferases and albumin, which can help to clarify the diagnosis and provide a basis for the treatment program. In summary, the role of liver function test for 8-month-old babies is to be able to do early detection and early treatment, which can help reduce the severity of liver cell damage and help the condition recover.
