Higher levels of ketones in the urine indicate that the body is using fat as the major source of energy. Ketone bodies that commonly appear in the urine when fats are burned for energy are acetoacetate and beta-hydroxybutyric acid. Acetone is also produced and is expired by the lungs. [1]
[1] [2] Breath may also develop the smell of acetone as it is a volatile ketone that can be exhaled. Rapid deep breathing, or Kussmaul breathing, may be present to compensate for the metabolic acidosis. [1] Altered mental status is more common in diabetic than alcoholic ketoacidosis. [2]
Ketones can be measured in the urine (acetoacetate) and blood (β-hydroxybutyrate). When compared with urine acetoacetate testing, capillary blood β-hydroxybutyrate determination can reduce the need for admission, shorten the duration of hospital admission and potentially reduce the costs of hospital care.

The concentration of ketone bodies in blood is maintained around 1 mg/dL. Their excretion in urine is very low and undetectable by routine urine tests (Rothera's test). [18] When the rate of synthesis of ketone bodies exceeds the rate of utilization, their concentration in blood increases; this is known as ketonemia.
Ketosis is a metabolic state characterized by elevated levels of ketone bodies in the blood or urine. Physiological ketosis is a normal response to low glucose availability. . In physiological ketosis, ketones in the blood are elevated above baseline levels, but the body's acid–base homeostasis is maintain
When the body relies on fats, rather than carbohydrates, as its main energy source, increased levels of ketones occur in the blood and urine. The presence of detectable levels of ketones in the urine is called ketonuria. Ketones occur in three forms in the body: beta-hydroxybutyrate (BHB), acetone and acetoacetate.

Elevated concentrations of ketones are not generally found in urine, as all these substances are completely metabolized, producing energy, carbon dioxide and water. However, the disruption of carbohydrate metabolism can lead to metabolic imbalances and the appearance of ketones as a by-product of the metabolism of an organism's fat reserves.
