The following erythrocyte indices were determined as part of a CBC: MCV 84 fL, MCH 24 pg, and MCHC 30 g/dL. What would you expect to observe on the Wright-stained peripheral blood smear?

Question

Quizplus · Accepted Answer

The MCHC value of 30 g/dL is lower than the normal range (32-36 g/dL), indicating that the erythrocytes have less hemoglobin than usual. This results in hypochromic erythrocytes on a peripheral blood smear. However, the MCV value of 84 fL indicates that the erythrocytes are of normal size, resulting in normocytic hypochromic erythrocytes. Therefore, the best choice is option C, hypochromic, normocytic erythrocytes.
