Sample Requirements

Specimen:  Whole Blood

Container(s):  Heparinized Syringe, 2 Capillary Blood Gas Tubes

Preferred Vol:  1.0 mL venous blood in a Heparinized Syringe, or 2 Full Capillary Blood Gas Tubes

Minimum Vol: 2 Heparinized Capillary Blood Gas Tubes. (EPOC capillary tubes are not acceptable).  

 

Note:  Expel air from syringe and cap it immediately after obtaining the sample. Capillary tubes must be filled completely and mixed thoroughly to dissolve and disperse the heparin. EPOC capillary tubes are not acceptable. Place specimen in OUTSIDE pocket of a pre-filled biohazard bag of ice, then put into a separate biohazard bag for transport.
