Hi and welcome to the forum! I am glad that I can help you.

You would like to know what ALT, AST and yGT mean.

ALT, AST and yGT are enzymes markers of the liver function. Alanine transaminase (ALT), also known as Serum glutamate pyruvate transaminase (SGPT) is an enzyme found in the highest amounts in the liver. AST is aspartate aminotransferase also known as Serum glutamic-oxaloacetic transaminase (SGOT). yGT means Gamma-glutamyl transpeptidase (GGT) and is also an enzyme found in the liver. Injury to the liver results in release of the substances into the blood, so their level would be increased. Damage to the liver may appear in hepatitis due to viral infection, alcohol consumption, cirrhosis, cancer and metastasis in the liver, etc.

Please keep in mind that I provide medical information only. I am not able to diagnose medical conditions online.
