USAID Advancing Nutrition’s HEME project has supported a laboratory-based multi-site study to compare Hb measurements from venous, pooled capillary, and single-drop capillary blood samples on different HemoCue® Hb models against a reference standard. In this webinar, speakers present the rationale, methods, and preliminary results of the study, and primary investigators share their varied experiences in carrying out the study under controlled laboratory conditions.
