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

Comprehensive metabolic profile testing (panels) is widely used to screen individuals who present for routine evaluation, as well as those referred for elevated liver enzyme values. The standard ...

Liver diseases are commonly diagnosed using serum enzyme assays, particularly for aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma-glutamyl ...

You’ve got your blood report back. There’s a mention of fatty liver. A couple of numbers labelled ALT and AST. Maybe a “grade” you don’t quite understand. And suddenly, it feels more confusing than ...

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 ...

Have you ever been told during a medical check-up that you need a liver function test and felt puzzled by terms like ALT, AST, and Total Bilirubin? You're not alone. Many people are unfamiliar with ...

Aspartate aminotransferase (AST) is an enzyme that’s present in various tissues of your body. An enzyme is a protein that helps trigger chemical reactions that your body needs to function. AST is ...

Rational testing: In the second of our series on how to rationalise testing in primary care, clinical scientist (biochemistry) Kade Flowers explains a logical approach to investigating a case of an ...

Doctors use the gamma-glutamyl transferase (GGT) blood test to diagnose liver problems. High levels of GGT can indicate damage to the liver or bile ducts, or other conditions. A typical range for GGT ...
