Capillary Blood Gas with Oxyhemoglobin
| Abbrev Code: | BGCOB | ||
| Order Code: | LAB5691 | Order Name: | Blood Gas Capillary with OXYHGB |
| Synonyms: | CBG | ||
| Methodology: | Specific electrodes (pH, pCO2, pO2); spectrophotometric analysis of hemolysate. % OxyHb = cOxyHb/ctHb; %O2Sat = cOxyHb/(ctHb -[cCOHb + cMetHb]) | ||
| CPT Codes: | 82805 x1 | ||
| Test Includes: | pH, pCO2, pO2, derived HCO3, oxyhemoglobin | ||
| Turnaround Time: | Performed and reported 24 hours/day. | ||
| Special Instructions: | Whole blood sodium, potassium, chloride, CO2, ionized calcium, lactate and glucose may be reuqested on this specimen. Provide FIO2 on request form. | ||
Collection Instructions
| Specimen: | Blood |
| Optimal Volume: | 0.1 mL |
| Minimum\Peds Volume: | 0.06 mL |
| Container: | Capillary (lithium heparin) gas tube |
| Collection Instructions: | Deliver to labortory immediately; if received within 30 minutes, ice is not required. The puncture should be deep enough to allow a free flow of blood. Collect into heparinized capillary tube, which is free of air bubbles, filled as much as possible, and capped on both ends. |
Processing and Shipping
| Specimen Processing: | Do not store. |
| Shipping Instructions: | Ship on wet ice to arrive within 2 hours. UMMC, FNMC and FLMC only: Do not send in PTS. |
| Stability: | Whole blood potassium is stable at room temperature for 2 hours. Whole blood potassium is stable on ice/gel packs for 30 minutes. |
