Metabolic Acidosis 1. Hyperchloremic or normal AG acidosis • Renal causes e.g. RTA, renal insufficiency • Urine AG is positive • Urine AG= Na+K-Cl (spot urine electrolytes) • Non-renal causes e.g. diarrhea • Urine AG is negative
Metabolic Acidosis 2. High AG acidosis: 1. Lactic acidosis, 2. Ketoacidosis, 3. Ingested toxins, • Aspirin • Ethanol, methanol, ethylene glycol (osmolal gap) 4. Acute or chronic renal failure
