mmol/L
Toxic levels for acetone are not well defined. Levels up to 15 mmol/L has been reported in patients with ketoacidosis.
Ingested isopropanol is metabolised to acetone therefore isopropanol toxicity does not cause a metabolic acidosis; the isopropanol level is usually higher than the acetone level. In patients with ketoacidosis, acetone is metabolised to isopropanol and acetone levels are usually higher than isopropanol level.
