WebNOTICE: This Calculator Panel is under BETA Testing (Please send us feedback and/or comments) Delta Gap is also called Delta Delta. The change in the anion gap divided by the change in the serum bicarbonate. Normal values default to HCO3 = 24 mEq/L and Anion Gap = 12 mEq/L. DD Ratio 1.0 = presence of concurrent non AG metabolic acidosis. WebA negative urine anion gap would be expect in diarrhea as the normal kidney attempts to regenerate bicarbonate and excrete ammonium. In renal tubular acidosis, the kidney is unable to excrete ammonium normally. Therefore the urine AG is "inappropriately" positive in the setting of a non-anion gap metabolic acidosis. kw-320 タニタ
