TGO and TGP, also known as transaminases, are enzymes normally measured with the aim of evaluating liver health. TGO, known as oxaloacetic transaminase or AST (aspartate aminotransferase) is produced in various tissues, such as the heart, muscles and liver, and is located inside liver cells. Therefore, when there is an increase in TGO levels alone, […]
