Biochemically, DKA is defined as an increase in the serum ketone concentration > 5 mEq/L, a blood glucose level > 250 mg/dL (although it is usually much higher), and a blood (usually arterial) pH < 7.3. Ketonemia and ketonuria are characteristic, as is a serum bicarbonate level ≤ 18 mEq/L or less (< 5 mEq/L is indicative of severe DKA). These biochemical changes are frequently associated with increased anion gap, increased serum osmolarity, and increased serum uric acid.
