The anion gap was 41. The plasma osmolarity was 314 mOsm/L. The plasma lactate was 25.9 mmol/L. The plasma pH was less than 6.8. His urine drug screen was negative for illicit drugs or ethanol.

Additionally, a bicarbonate level equal to or less than 18 millimoles per liter (mmol/l) and an anion gap of more than 10 mmol/l indicate DKA. Doctors classify DKA as mild, moderate, or severe.

The anion gap is calculated by Sodium (Chloride + Bicarbonate). [13] Hyperchloremic acidosis is a hallmark of metabolic acidosis due to bicarbonate wasting and usually occurs in newborns with ...
