Macrocytic red blood cells are described as which?

Explanation:
Macrocytosis means red blood cells are larger than normal. This shows up as an increased mean corpuscular volume (MCV), typically over about 100 fL. The larger size arises when DNA synthesis is impaired (as in vitamin B12 or folate deficiency), causing nucleus maturation to lag behind cytoplasmic growth and producing oversized cells. You’ll often see this pattern in megaloblastic processes, but macrocytosis can also occur with liver disease, alcoholism, hypothyroidism, or certain drugs. The essential point is that the cells themselves are bigger than usual, not normal size or fewer in number.
