%X Anemia remains a major public health issue in many African communities. We compared a novel, commercially available noninvasive hemoglobin (Hb)每measuring device to direct Hb measurements by finger-prick samples in a pediatric cohort in rural Cˋte d'Ivoire. Noninvasive Hb measurements were attempted in 191 children 2每15 years of age and obtained in 102 (53.5%) children. The median Hb for the 102 children was 12.0 g/dL (interquartile range [IQR] = 11.3每12.7 g/dL) for conventional absorptiometry and 13.3 g/dL (IQR = 12.1每14.2 g/dL) for noninvasive measurements. A Bland每Altman analysis demonstrated a median bias of +1.1 g/dL (IQR = 0.4每2.0 g/dL), with greater overestimation of Hb by noninvasive testing occurring at low Hb values. This overestimation of the noninvasive Hb每measuring device to direct Hb measurements persisted across preschool- and school-aged children, and both sexes. The Pearson correlation coefficient was 0.50 for children 4每9 years of age, and 0.33 for children 10每15 years of age. Further study and development of noninvasive Hb devices is necessary prior to implementation in African pediatric populations
