Collection Instructions

Specimen:Non-Roche sites: whole blood; do not centrifuge
Roche: Blood
Optimal Volume:Non-Roche sites: 1 mL
Roche: 2.5 mL
Minimum\Peds Volume:Non-Roche sites: 0.1 mL
Roche: 0.6 mL
Container:Green (lithium heparin, gel)
Alternate Containers: Purple (EDTA), Red (no gel), Red (gel), St Johns/Woodwinds-Green (lithium heparin, no gel)
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:Non-Roche sites: Do not store.
Roche: Centrifuge and aliquot 1 mL of plasma/serum, 0.5 mL minimum. Store in refrigerator.
Shipping Instructions:Roche: Ship at refrigerated temperature.
Stability:Roche: 1 week at refrigerated temperature
Test Performed at or Referral Lab Chemistry  (Range, Ridges, Roche-Grand Itasca, Roche-Lakes, Roche-Northland, Roche-Southdale, Roche-St. John's, Roche-UMMC East, UMMC/UMMCH-West Bank, Woodwinds)


Interpretive

Critical Range:Greater than 1.5 mmol/L
Reference Range:Non-Roche sites: 0.0-0.6 mmol/L
Roche: ≤0.30 mmol/L
Use:Evaluate ketoacidosis, usually with diabetes mellitus. The method measures beta-hydroxybutyrate, which is elevated more reliably in diabetics with ketoacidosis, rather than acetoacetate.
