The ALT (Alanine Aminotransferase), also known as SGPT (Serum Glutamate Pyruvate Transaminase), is a liver enzyme that plays a key role in amino acid metabolism. It is primarily found in liver cells, making it a highly specific marker for liver health.
AST (Aspartate Aminotransferase), also called SGOT (Serum Glutamic-Oxaloacetic Transaminase), is another enzyme involved in amino acid metabolism, found in the liver, heart, muscles, kidneys, and brain.
These tests are commonly used together to detect liver damage or disease, monitor liver health during medication use, and evaluate symptoms such as jaundice, nausea, or abdominal pain.
