Ketones (Beta Hydroxybutyrate) by Meter, Blood


Abbrev Code:KETONE   
Order Code:LAB3224Order Name:Ketone (Beta-Hydroxybutyrate) Quantitative
Synonyms:Beta-Hydroxybutyric Acid (Rapid)
Methodology:B-Hydroxybutyrate dehydrogenase reaction (Medisense Precision Xtra)
CPT Codes: 82010 x1
Test Includes:Test measures B-hydroxybutyrate (B-Ketone), the most important of the three ketone bodies.
Turnaround Time:Performed 24 hours/day.
Special Instructions:Specimen must be sent to lab immediately. Testing must be performed within 30 minutes of collection.


Collection Instructions

Specimen:Whole blood; do not centrifuge
Optimal Volume:1 mL
Minimum\Peds Volume:0.1 mL
Container:Green (lithium heparin, gel), Grand Itasca - Green (lithium heparin, no gel), St Johns/St Joseph/Woodwinds - Red (no gel)
Alternate Containers: Grand Itasca - Red (no gel), Purple (EDTA), Red (no gel), St Johns/St Joseph/Woodwinds-Green (lithium heparin, no gel), Dry heparin syringe
Contraindications:High hematocrits (above 60%) may yield falsely lower results and lower hematocrits (below 30%) may cause falsely high results. Test results may be erroneously low if patient is severely dehydrated, or severely hypotensive, in shock, or in hyperglycemic-hypersmolar state.


Processing and Shipping

Specimen Processing:Do not store.
Test Performed at or Referral Lab Chemistry  (Range, UMMC-East Bank, Lakes, Ridges, Northland, Southdale, UMMC/UMMCH-West Bank, St. John's, Woodwinds)


Interpretive

Critical Range:Greater than 1.5 mmol/L
Reference Range:0.0-0.6 mmol/L
Use:Evaluate ketoacidosis; usually with diabetes mellitus. The method preferentially measures beta-hydroxybutyrate, which is elevated more reliably in diabetics with ketoacidosis, rather than acetoacetate.
