Aka: Urinary Anion Gap, Urine Anion Gap
  1. Indications
    1. Non-Anion Gap Metabolic Acidosis
    2. Distinguishes renal from extra-renal causes
  2. Physiology: Measures unmeasured anions present in urine
    1. Sulfates
    2. Phosphates
    3. Bicarbonates
    4. Organic anions
      1. Lactate
      2. Citrate
  3. Calculation
    1. UAG = Urine Sodium + Urine Potassium - Urine Chloride
  4. Interpretation: Normal
    1. UAG = -10 to +10
  5. Interpretation
    1. Decreased Urine Anion Gap <-10
      1. Extrarenal Non-Anion Gap Metabolic Acidosis
    2. Increased Urine Anion Gap >+10
      1. Renal Non-Anion Gap Metabolic Acidosis
