Hemoglobin Concentration

The amount of central pallor is related to the hemoglobin concentration in the red blood cells (RBCs). When viewing normal mature RBCs on a Wright-stained smear, the central area (one-third of the cell) is pale, while pink- or buff-colored hemoglobin is visible in the outer two-thirds of the cell. The mean corpuscular hemoglobin concentration(MCHC) is an indice that represents the average concentration of hemoglobin in a deciliter (dL) of erythrocytes. A normal MCHC is approximately 32-36 g/dL.
