Venous Blood Gas with Oxyhemoglobin


Abbrev Code:BGVOB   
Order Code:LAB3323Order Name:BL Gas Venous and O2HB Panel
Synonyms:VBG
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 requested on this specimen. Provide FIO2 on request form.


Collection Instructions

Specimen:Blood
Optimal Volume:1 mL
Minimum\Peds Volume:0.5 mL (3 mL syringe); 0.2 mL (tuberculin syringe)
Container:Dry heparin syringe
Collection Instructions:UMMC East Bank only: Place sample on ice if analysis may be more than 30 minutes from time of collection.
All Other Sites: DO NOT COLLECT ON ICE. Sample must be received within 30 minutes of collection.
