Comparative StudyDetermination of circulating hemoglobin mass and related quantities by using capillary blood.
A standardized carbon monoxide (CO) rebreathing procedure with measurements of CO-hemoglobin, hemoglobin concentration ([Hb]), and hematocrit (Hct) enables to determine total Hb mass (Hb(tot)), blood, erythrocyte, and plasma volume (BV, EV, and PV). These calculations are normally based on venous blood samples. However, micromethods also allow determinations from capillary blood. ⋯ Calculation of Hb(tot) using capillary blood is as accurate and reliable as using venous blood.
