Anion gap is increased in all except?: (A) Renal tubular acidosis, (B) Diabetic ketoacidosis, (C) Acute tubular necrosis, (D) Ethylene glycol poisoning
Answer is A. Anion gap: The anion gap is the difference between primary measured cations and the primary measured anions in serum. AG= Na-(Cl- + HCO3-) Value of Normal anion gap= 10 to 12 mmol/L Anion gap is increased in: Diabetic ketoacidosis Acute tubular necrosis Ethylene glycol poisoning
