|Blood glucose measurement is most commonly used as a screening test for diabetes mellitus. It may also be performed to evaluate carbohydrate metabolism in conditions such as acute hepatitis, pancreatitis and Addisons disease. Blood glucose levles may also be measured when hypoglycaemia is suspected. Hypoglycaemia can be caused by exogenous insulin, neonatal respiratory distress, toxaemia of pregnancy, congenital enzyme defects, Reyes syndrome, alcohol ingestion, hepatic dysfunction, insulinoma, septicaemia and chronic renal failure.
