What is the meaning of SGPT enzyme?
SGPT also as ALT …….. here’s a clip from the Merck Manual on ALT levels Aminotransferases: Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) leak from damaged cells, making them sensitive indicators of liver injury. Acute hepatocellular necrosis or injury (eg, hepatitis) typically results in high values (500 to > 2000 IU/L; normal, ≤ 40 IU/L), usually for days or, in viral hepatitis, weeks. Serial measurements better reflect severity and prognosis than do single values: a fall to normal indicates recovery unless accompanied by a rise in bilirubin and PT or INR (which may predict massive liver failure). Modest elevations (100 to 300 IU/L) persist in chronic liver diseases. In biliary obstruction, values usually are < 300 IU/L, except where passage of a common duct stone transiently increases levels to the thousands. Values < 100 IU/L are nonspecific. Although ALT is somewhat specific for liver disease, AST may be elevated because of rhabdomyolysis or damage to hear
