Which term describes reduced hemoglobin content in erythrocytes?

• A. Polychromasia
• B. Hyperchromasia
• C. Basophilia
• D. Hypochromasia

Answer: (D)

Think about how a stained red blood cell’s color reflects its hemoglobin content. When there’s less hemoglobin in a cell, it stains lighter and the central pale area (central pallor) becomes more prominent. That pale, under-hemoglobinized appearance is described as hypochromasia. It’s commonly seen with microcytic red cells in conditions like iron deficiency or thalassemia, and it ties to a lower MCHC. The other terms describe different features: polychromasia refers to bluish cytoplasm from young reticulocytes, basophilia indicates basophilic staining from RNA or basophilic stippling, and hyperchromasia would imply an abnormally darker cell stain, which isn’t typical for normal erythrocytes.
