Viral Hemorrhagic Fever (VHF) Blood Gases, Lactate - Blood

Source Blood
Mnemonic CG4+V for venous collections
CG4+A for arterial collections
Specimen Requirements

Lithium Heparin Whole Blood or 2 dry lithium heparin syringes.
Do not centrifuge tube.

Minimum sample 300 µL Lithium Heparin Whole Blood

VHF chemistry panels (WBCMP and WBLPP), blood gases, ionized calcium, lactate, BHCG and Troponin I can all be performed on 1mL lithium heparin whole blood.

Specimen Handling Sample must be analyzed within 60 minutes of collection.
Additional Information

If Ebola Virus Disease (EVD) or other viral hemorrhagic fever (VHF) is suspected, the ordering physician MUST contact the local zone Medical Officer of Health by the fastest means possible. ANY and ALL laboratory testing for patients with suspected EVD or VHF MUST be coordinated and approved through the local zone Medical Officer of Health.

CG4+V panel includes pH, pCO2, base excess, HCO3, sO2, lactate

CG4+A panel includes pH, pCO2, pO2, base excess, HCO3, sO2, lactate

CLS staff: Refer to the VHF Documents section of the BCERP manual for enhanced safety procedures.
