Do you prefer using the delta ratio or corrected bicarbonate formula when further evaluating a patient with high anion gap metabolic acidosis?

I use the delta AG/delta HCO3 ratio in evaluating a patient with high anion gap metabolic acidosis. It is important to recognize that the delta AG/delta HCO3 ratio in lactic acidosis averages approximately 1.6, whereas the delta AG/delta HCO3 ratio in ketoacidosis averages approximately 1.
