Quizplus · Accepted Answer

A lack of intrinsic factor is associated with pernicious anemia, which can lead to a deficiency of vitamin B12 and the presence of large pale cells called macrocytes. Sickle-cell anemia is a genetic disorder characterized by abnormal hemoglobin, not a deficiency of vitamin B12. Aplastic anemia is a condition where the bone marrow does not produce enough new blood cells, and polycythemia is a condition where there is an excess of red blood cells. Neither of these conditions are associated with a deficiency of vitamin B12 or intrinsic factor.
