Smaller than normal red blood cells due to insufficient hemoglobin describe which category?

Smaller than normal red blood cells due to insufficient hemoglobin describe which category?

• A. Hypochromic
• B. Normocytic
• C. Microcytic
• D. Macrocytic

Answer: (C)

Microcytosis is when red blood cells are smaller than normal, usually because hemoglobin production is reduced. When iron deficiency or disorders like thalassemia limit hemoglobin synthesis, the cells don’t grow to their full size, so the mean cell volume is low and the cells appear small. Hypochromic refers to pale cells from low hemoglobin content, which can accompany microcytosis but is about color, not size. Normocytic means normal-sized cells, and macrocytic means larger-than-normal cells, as seen with B12 or folate deficiency. So the description points to microcytic.
