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. |
