Complications of Diabetes Increased incidence of infection due to the Increased incidence of infection due to the
three primary manifestations of diabetes:three primary manifestations of diabetes:1. 1. Hyperglycemia:Hyperglycemia: decreases phagocytic
function of granulocytes. Facilitates microorganisms to grow.
2. 2. Ketoacidosis: Ketoacidosis: delays migration of granulocytes to injury. Dec. phagocytic activity.

Diagnosing DiabetesLab tests demonstrating Lab tests demonstrating
abnormal glucose metabolism:abnormal glucose metabolism: Fasting Plasma Glucose (FPG) Fasting Plasma Glucose (FPG)
test:test: (The “gold standard” lab test). Patient (The “gold standard” lab test). Patient fasts 10-16 hrs. For fasting blood glucose, fasts 10-16 hrs. For fasting blood glucose, normal = 70-115mg/100ml of plasma. Results normal = 70-115mg/100ml of plasma. Results >126mg/100ml with 2 tests = dx. diabetes m. >126mg/100ml with 2 tests = dx. diabetes m.
