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; p<0.05). There was high agreement between Hb in capillary blood by the HemoCue  and in venous blood by the counter (r icc =0.86; p<0.01), and also between the diagnosis of anemia by both equipments (k=0.81; p<0.01). The HemoCue  seems to be more appropriate for capillary blood and require training of the measurers. (12,4 e 11,7 g/ dL, respectivamente; p<0,05 =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. Resumo
