Useful For
Monitoring therapy for diabetic ketoacidosis
Investigating the differential diagnosis of any patient presenting to the emergency room with hypoglycemia, acidosis, suspected alcohol ingestion, or an unexplained increase in the anion gap
In pediatric patients, the presence or absence of ketonemia/uria is an essential component in the differential diagnosis of inborn errors of metabolism
Serum beta-hydroxybutyrate is a key parameter monitored during controlled 24-hour fasts
Specimen Linearity
Specimens are linear to 47.8
Instrument will automatically dilute samples x 2. If still out side linearity report as greater than 95.6 mg/dL.
If physician requires an endpoint, please dilute X 10 manually with water and report.
