The AST:ALT ratio in a healthy individual would be around 1.15. If the ratio is more than 2.0 (up to 6.0), this denotes alcoholic liver disease. And if the ratio is between 1.4 and 2.0, it suggests cirrhosis. Interestingly enough, the severity of cirrhosis is mea...
The aim of this study was to evaluate the effect of initial aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels and preexisting liver disease, including cirrhosis, in a cohort of patients admitted with COVID infection at a tertiary care hospital network in the Bronx, New ...
low; if levels are raised this may signify that the individual has an infection or illness, which is affecting their liver. Very high levels are usually symptomatic of acute hepatitis, while levels that are higher than average may signify chronic hepatitis, liver cancer and cirrhosis of the ...
Interpretation of the AST ALT ratio Too high of an AST ALT ratio and high levels of AST and ALT. A ratio of AST ALT greater than 1 can be indicative of cirrhosis - a scar tissue transformation of the liver that eventually results in a loss of its function. AST ALT ratio > 2 strongly...
在肝细胞中,与天冬氨酸转氨酶(AST)主要(80%)存在于线粒体内不同,ALT 主要存在于非线粒体中,即细胞质中。ALT 为非特异性细胞内功能酶,正常状态下血清含量很低。当肝细胞或其细胞膜受损时,转氨酶会释放入血液循环中,使血清转氨酶...

The AST:ALT ratio may become elevated over 1 in cirrhosis, muscle damage, biliary obstruction, and Wilson’s disease.[i] [ii] [iii] [iv] [v] Liver disease The AST:ALT ratio can assist in grading severity of pathology in chronic liver disease including alcoholic liver disease and chronic...
(1)肝功能指标:ALT、AST、TBil水平;(2)总有效率:总有效率=显效率+有效率(显效:ALT和AST降至正常值上限以下,TBil基本恢复正常,临床症状消失;有效:ALT和AST降至正常值上限的2倍以下,TBil降至治疗前的50%以下,临床症状有所改善);...
AST/ALT ratio was first put forward in 1957 for the diagnosis of viral hepatitis [9]. Subsequently, a number of studies found that the ratio > 1.00 suggested cirrhosis in patients with chronic viral hepatitis, non-alcoholic steatohepatitis (NASH), alcoholic liver disease (ALD) and primary bilia...
