To determine the precision and agreement of the hemoglobin (Hb) measurements in capillary and venous blood samples by the HemoCue® and an automated counter. Hb was determined by both equipaments in blood samples of 29 pregnant women. The HemoCue® showed low repeatability of Hb measurements in duplicate in capillary (CR=0.53 g/dL, CV=13.6%) and venous blood (CR=0.53 g/dL, CV=13.6%). Hb measurements in capillary blood were higher than those in venous blood (12.4 and 11.7 g/dL, respectively; pCom o objetivo de avaliar a precisão e concordância na determinação de hemoglobina (Hb) em sangue capilar e venoso, utilizando-se o HemoCue® e um contador automático, foram estudadas 29 gestantes. O HemoCue® apresentou baixa repetibilidade para as medidas em duplicata em sangue capilar (CR=0,53 g/dL; CV=13,6%) e venoso (CR=0,53 g/dL; CV=13,6%). As medidas de Hb obtidas em sangue capilar foram mais altas do que as obtidas em sangue venoso (12,4 e 11,7 g/dL, respectivamente; p<0,05). Verificou-se alta concordância entre medidas de Hb em sangue capilar obtidas pelo HemoCue® e em sangue venoso pelo contador (r icc=0,86; p<0,01), bem como entre os diagnósticos de anemia realizados nos dois equipamentos (k=0,81; p<0,01). O HemoCue® parece ser mais apropriado para análise de Hb em sangue capilar, mas é necessário um treinamento dos analisadores.
