DKA: diabetic ketoacidosis; +: positive; BUN: blood urea nitrogen.

* Respiratory alkalosis/metabolic acidosis.

¶ May get false-positive or false-negative urinary glucose caused by the presence of salicylate or its metabolites.

Δ Acetest and Ketostix measure acetoacetic acid only: thus, misleading low values may be obtained because the majority of "ketone bodies" are beta-hydroxybutyrate.
