FDA Status
This test was developed and its analytical performance characteristics have been determined by Quest Diagnostics. It has not been cleared or approved by FDA. This assay has been validated pursuant to the CLIA regulations and is used for clinical purposes.

Patients with diabetes who may also have lactic acidosis may have false negatives or falsely weak reactions. With these patients a beta-hydroxybutyrate measurement may be preferred. High concentrations of levodopa may produce false positives. Ketogenic or low/no-carb diets, often instituted for pediatric epilepsy, may also produce false positive results.

Reference Range
None detected

Clinical Significance
Excessive formation of ketone bodies (acetone) results in increased blood levels (ketonemia) and increased excretion in the urine (ketonuria). This condition is associated with a decreased availability of carbohydrates, such as dieting or decreased use of carbohydrates. Diabetes and alcohol consumption are common causes of ketoacidosis. Acetone is one ketone body formed from acetoacetate. Ingestion of isopropyl alcohol also leads to the formation of acetone.
