Useful For

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.
