Agreement Between Venous and Capillary Haemoglobin Concentrations in Bangladeshi Children (P10-105-19)

There are concerns that capillary haemoglobin (Hb) concentrations do not agree with venous Hb, which has implications for global estimates of anaemia largely derived from capillary Hb. In children enrolled in the Benefits and Risks of Iron Supplementation in Children (BRISC) trial, we examined differences between Hb concentrations collected from venous and capillary blood samples, and predictors of these differences. Hb concentrations were measured in 3300 children at 8 months of age. Capillary Hb concentrations were measured during screening of children for inclusion in the trial. Venous Hb was measured up to 10 days after screening, during enrolment. All Hb measurements used the HemoCue® 301. In children who received both capillary and venous measurements, Hb means, standard deviations, and anaemia…
