Normocytic anemia - ANSWER due to hemorrhage or chronic disease. Aplastic anemia.
MVC 80-92
macrocytic anemia - ANSWER due to folate or vitamin B12(cobalamin) deficiency

PPIs and histamine2 blockers can cause this.
Increased homocysteine & methylmalonic acid level indicates ? - ANSWER B12
deficiency
increased homocysteine levels - ANSWER Folate deficiency
Sperocytes - ANSWER Appear as spheres, lack central pallor, smaller diameter,
indicate immune-mediated process - can be seen after blood transfusion
aplastic anemia - ANSWER a normocytic anemia characterized by the failure of bone

Low ferritin - ANSWER iron deficiency anemia
Transferrin - ANSWER transports iron
