A rise in the alkaline phosphatase occurs with all forms of cholestasis, particularly with obstructive jaundice. Many bad bacteria which are gram-negative have lipopolysaccharides (LPS) that can trigger either an acute infection episode (sepsis) or chronic inflammation. Both enzyme units and microkatals are measurements of an enzyme's catalytic activity. The normal range is 44 to 147 international units per liter (IU/L) or 0.73 to 2.45 microkatal per liter (kat/L).
