In liver fibrosis, the AST:ALT ratio is especially useful because it can identify fibrosis even when both AST and ALT are within normal lab range. When the AST:ALT ratio rises above 1, fibrosis can be suspected, indicating that all is not normal.[viii] Non-alcoholic fatty liver disease (...
AST:ALT ratio Although the normal range of AST and ALT level varies among laboratories and countries, the ratio of AST:ALT is key when it comes to diagnosing liver diseases. The use of this ratio was first suggested by de Ritis in 1955. He found that the ratio d...
Anything above or below the normal range may lead your doctor to order more tests. But most people with abnormal levels on a single ALT test won't turn out to have aserious health problem. When should I worry about ALT and AST?
Too Low AST ALT ratio - check the section below. The interpretation of an elevated and normal AST ALT ratio is based on many factors. We need to evaluate the value of the ratio and the value of its singular components. Your physicians will also check for other signs or symptoms of liver...
What is considered a normal range for ALT and AST? Normal ranges can vary by lab but typically fall between 7-56 units per liter of serum for ALT and 5-40 units for AST. 8 Is AST a reliable standalone indicator of liver health? Not as reliable as ALT; it's best to consider AST ...
1， 临床上常用AST（谷草转氨酶）/ALT（谷丙转氨酶）的比值来反映肝细胞的损害情况。肝病时AST/ALT比值＜1，常提示肝脏损害较轻，AST/ALT比值＞1，则提示肝脏损害较重。但是在ALT,AST数值均在正常值范围内时其比值没有意义 。你的AST/ALT为 0.66 ，视为小于1，不必纠结在不在其比值范围内，希望...
AST:ALT ratio of more than 2:1 is characteristic in patients with alcoholic liver disease a raised AST level out of proportion to the ALT level appears to be caused by a differential reduction in hepatic ALT due to deficiency of the cofactor pyridoxine-5-phosphate ...

The aspartat aminotransferase (AST)/alanin aminotransferase (ALT) (De-Ritis) ratio (AAR) is an easily applicable blood test. An elevated AAR on the one hand has been associated with an increase in nonalcoholic fatty liver disease (NAFLD). NAFLD on the other hand is associated with an incre...
