However, very high elevations of the transaminases suggests severe liver damage, such as viral hepatitis, liver injury from lack of blood flow, or injury from drugs or toxins. Most disease processes cause ALT to rise higher than AST; AST levels double or triple that of ALT are consistent with alcoholic liver disease. [citation needed]
The liver transaminases aspartate transaminase (AST or SGOT) and alanine transaminase (ALT or SGPT) are useful biomarkers of liver injury in a patient with some degree of intact liver function. [2] [3] [4] Most liver diseases cause only mild symptoms initially, but these diseases must be detected early. Hepatic (liver) involvement in some ...
The ratio of aspartate aminotransferase to alanine aminotransferase is usually 2 or more. [13] In most cases, the liver enzymes do not exceed 500. A liver biopsy is not required for the diagnosis, however it can help confirm alcoholic hepatitis as the cause of the hepatitis if the diagnosis is unclear. [3] [14]
In people with alcoholic hepatitis, the serum aspartate aminotransferase (AST) to alanine aminotransferase (ALT) ratio is greater than 2:1. AST and ALT levels are almost always less than 500. The elevated AST to ALT ratio is due to deficiency of pyridoxal phosphate, which is required in the ALT enzyme synthetic pathway.
The AST/ALT ratio or De Ritis ratio is the ratio between the concentrations of two enzymes, aspartate transaminase (AST) and alanine transaminase, aka alanine aminotransferase (ALT), in the blood of a human or animal. It is used as one of several liver function tests, and measured with a blood test.
Aspartate transaminase (AST) or aspartate aminotransferase, also known as AspAT/ASAT/AAT or (serum) glutamic oxaloacetic transaminase (GOT, SGOT), is a pyridoxal phosphate (PLP)-dependent transaminase enzyme (EC 2.6.1.1) that was first described by Arthur Karmen and colleagues in 1954.

In one study that examined people over 15 years, 11% of those with MASH developed cirrhosis as compared to less than 1% of people with MASLD. [126] Other estimates have shown that MASLD and MASH were found to worsen with cirrhosis in respectively 2–3% and 15–20% of the people over a 10–20 year period. [ 13 ]
