Do you consider hyperuricemia as a potential etiology of an anion gap metabolic acidosis in patients with elevated uric acid levels and no other readily explainable causes of acidosis?

Urate has a molecular weight of ~166 mg/mmole and the valence of the anion is -1.

Hence, let us say we have severe hyperuricemia with 16 mg/dl. That will provide an "anion gape" of only 1!

So, by itself, urate cannot increase the anion gap.

Could hyperuricemia be a "biomarker" of other causes of met...
