Comparison of massimo pronto-7 and hemocue hb 201 with laboratory haemoglobin estimation: A clinical study

Abstract

We prospectively studied agreement in haemoglobin estimation between two point-of-care devices (Pronto-7 Pulse CO-Oximetry™, Masimo Corporation, Irvine, California, USA and HemoCue Hb 201+, HemoCue, Angelholm, Sweden) and an automated laboratory analyser (Sysmex XE5000, Sysmex Corporation, Kobe, Japan). Venous blood sampling and finger co-oximeter readings were performed on 141 pregnant women undergoing routine mid-trimester haemoglobin assessment. Three replicate measures were performed and analysis used Bayesian-based variance component modelling to provide estimates of repeatability, between person within method bias and precision. Repeatability, assessed by coefficient of variation, was ..
