The New Noninvasive Occlusion Spectroscopy Hemoglobin Measurement Method: A Reliable And Easy Anemia Screening Test For Blood Donors.

The tests used for anemia screening in blood donors are based on fingerstick samples, leading to discomfort and complaints. The aim of this study was to analyze the feasibility of occlusion spectroscopy method in blood banks and to compare the method with fingerstick hemoglobinometer and hemoglobin (Hb) determination on an automatic blood analyzer. The study enrolled 205 consecutive volunteer blood donors. Samples were collected by fingerstick and venous punction to determine Hb level by a Hemocue Hb201+ (Hb-F) and automatic blood analyzer (Hb-V) and compare to the noninvasive Hb determination by occlusion spectroscopy using NBM200 system (Hb-NI). The percentage errors of Hb-F and Hb-NI of all donors as well as stratified by sex, weight, and age levels were compared to Hb-V as reference values using Wilcoxon signed rank test. The results obtained with Hb-F showed significant errors (p
