Also, if volume depleted secondary to GI losses, may be a false-positive urine ion gap. Increased anion-gap acidosis. Uremia or renal failure. Alcoholic ketoacidosis or diabetic ketoacidosis. Can measure for these substances directly, but the first step is to determine the osmolal gap as noted previously.
Treatment depends on the underlying condition.
Metabolic Alkalosis Definition. Implies a loss of acid or gain of bicarbonate. ECF volume contraction, hypokalemia, and increased mineralocorticoids or glucocorticoids all impair the normal kidney's ability to excrete excess HCO 3 - and may result in a metabolic alkalosis. Additionally, excess exogenous bicarbonate should be in the differential. The urinary Cl - level is measured to help differentiate the causes of metabolic alkalosis.
