Ketonuria
September 10th, 2020
Overview
Urine does not normally contain ketones, though a small amount may be present after vigorous exercise, vomiting or diarrhoea. Significant amounts of urinary ketone suggest the presence of ketosis.
There are three types of ketone - acetone, acetoacetic acid and betahydroxybutyrate. The nitroprusside method used in dipsticks is most sensitive for acetoacetic acid.
