NOT one of the three main categories of anaemia based on red blood cell size?

Explanation:
The main idea is that anemia is grouped by red blood cell size using mean corpuscular volume (MCV): microcytic means smaller than normal, normocytic means normal size, and macrocytic means larger than normal. Hypochromic, on the other hand, describes cells that are paler than normal due to less hemoglobin per cell. It’s about color and hemoglobin content, not the size of the cells. So it isn’t one of the size-based categories. In fact, you can see microcytic anemia that’s hypochromic (small and pale) when iron deficiency is present, illustrating how color and size can vary independently.
