The American Diabetes Association requires a plasma glucose concentration greater than 250 mg/dL to diagnose diabetic ketoacidosis (DKA). However, with the new diabetic agents this is not always the case. With the introduction of SGLT2 inhibitors (canagliflozin [Invokana], dapagliflozin [Farxiga], empagliflozin [Jardiance]) there have been reported cases of DKA and patients being euglycemic.
Take Home Point
Patients with a low/normal blood glucose can still have DKA. Especially if they are taking newer medications, such as the SGLT2 inhibitors.
