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

Optimal Volume:1 mL
Minimum\Peds Volume:0.5 mL (3 mL syringe); 0.2 mL (tuberculin syringe)
Container:Dry heparin syringe
