Answer

The only definitive way to diagnose metabolic acidosis is by simultaneous measurement of serum electrolytes and arterial blood gases (ABGs), which shows pH and PaCO2 to be low; calculated HCO3- also is low. (For more information, see Metabolic Alkalosis.)

A low serum HCO3- and a pH of less than 7.40 upon ABG analysis confirm metabolic acidosis.
