Liver enzymes are proteins in your liver that speed up chemical reactions. If your liver is damaged, blood tests will show abnormally high levels of these enzymes circulating in your bloodstream.

Background Gamma glutamyltransferase (GGT), alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP), commonly used as markers of liver dysfunction, have been ...

A new population-based epidemiological study has found that elevated liver enzymes discovered during routine medical care are associated with higher future mortality. A new population-based ...

Elevated liver enzymes may mean a person’s liver is not working properly. Common causes include fatty liver disease and cirrhosis. Managing these conditions will help treat high enzyme levels. Doctors ...

Is it significant? A seemingly relevant abnormality in these tests must be interpreted in context. The decision about the need for further diagnostic evaluation and/or the most appropriate evaluation ...

An AST blood test measures levels of aspartate aminotransferase (AST) and helps determine liver function. Less than 40 IU/L is normal, but too much of this enzyme can indicate a problem, such as liver ...

Tips for interpreting elevated hepatic enzymes Evaluating abnormal hepatic enzymes is common in primary care practice and understanding the causes is essential for developing proper treatment plans.

The aspartate aminotransferase (AST) test is a blood test that looks for liver damage by checking the levels of aspartate aminotransferase (also known as aspartate transferase) in your blood. Your ...

The study comprised 718 adolescents (397 girls). PA was measured by accelerometry and expressed as total PA (counts/min), and time (min/d) engaged in moderate to vigorous intensity PA (MVPA). Time ...
