Validation of the Hemo_Control instrument for determination of B-haemoglobin concentration in primary health care

AbstractObjective: The aim of this study was to evaluate the analytical performance of a new portable haemoglobinometer, Hemo_Control (EKF-diagnostic, GmbH, Germany), which measures haemoglobin concentration in venous and capillary samples. Method: The within series and between series imprecision of the Hemo_Control instrument were calculated after measuring the concentration of venous samples under standardized conditions; by experienced laboratory technicians in a hospital laboratory, and venous and capillary samples under conditions similar to where the instrument is intended for use; by personnel at two primary health care centres. The bias of the Hemo_Control instrument was calculated as the difference between its results and results obtained with a Coulter LH 750 instrument traceable to the ICSH reference method. Results: The uncertainty of the Hemo_Control instrument for venous samples was lower than the quality goal of ± 5% considered acceptable for patient care. High within series imprecision (5....
