Point-of-Care Hemoglobin/Hematocrit Testing: Comparison of Methodology and Technology

摘要

Objective: Point-of-care (POC) testing allows rapid assessment of hemoglobin (Hgb) and hematocrit (Hct) values. This study compared 3 POC testing devices-the Radical-7 pulse oximeter (Radical-7, Neuchtel, Switzerland), the i-STAT (Abbott Point of Care, Princeton, NJ), and the GEM 4000 (Instrumentation Laboratory, Bedford, MA) to the hospital reference device, the UniCel DxH 800 (Beckman Coulter, Brea, CA) in cardiac surgery patients.
