New cards

  • red cell morphology would be normochromic and macrocytic

  • the lymphocyte peak starts early and ends early

  • this patient likely has a folate or B12 deficiency

  • the smear would show marked anisocytosis

  • there is a decrease in the number of granulocytes

  • there is a decrease in the total number of red cells

  • this patient has a macrocytic anemia

  • the R1 flag can mean platelet clumps, giant platelets, sickle cells, nRBCs, or intracellular parasites

  • platelets are basically normal

  • this slide would likely have some hypersegmented neutrophils
