1 The blood tests most frequently used for liver disease are the aminotransferases (alanine aminotransferase or ALT and aspartate aminotransferase or AST). 2  Normal levels of ALT ranges from about 7-56 units/liter, and 10-40units/liters for AST. Many drugs may cause elevated AST, and ALT and some medications can cause severe damage (for example, acetaminophen [ Tylenol liver damage]). 2  Less common causes of abnormal AST and ALT levels are wide ranging (for example, toxins, and autoimmune diseases).
â¢ History of alcohol use. â¢ Increase ALT and AST level on liver function test. â¢ Known case of breast cancer. â¢ Currently taking lisinopril. Normal range for ALT 10-40, AST 10-35. So from your reports it is clear that ALT and AST levels are elevated.ALT and AST elevate in presence of parenchymal damage because of alcohol use and they return in normal range after stoppage of alcohol.Alanine transaminase (ALT), also called Serum Glutamic Pyruvate Transaminase (SGPT) is an enzyme present in hepatocytes (liver cells).levated AST levels are not specific for liver damage, and AST has also been used as a cardiac marker and in certain cancers. The AST/ALT ratio is sometimes useful in differentiating between causes of liver damage (hepatotoxicity).
