The SGOT (AST) test is a core component of your Liver Function Test (LFT) panel. It measures a key enzyme found in your liver, heart, and muscle cells. When these cells are damaged, they release SGOT into the bloodstream. While it's a vital indicator of liver inflammation (like hepatitis), it also provides clues about potential muscle or heart stress. This simple blood draw is essential for a broad-spectrum look at your internal health. This is a critical, foundational enzyme test that helps your doctor protect your vital organs.
