Question: Microcytic anemia
Answer:
iron deficiency, usually due to malabsorption / occult blood loss, or lead poisoning. MCV <80
Question: Normocytic anemia
Answer:
due to hemorrhage or chronic disease. Aplastic anemia. MVC 80-92
Question: macrocytic anemia
Answer:
due to folate or vitamin B12(cobalamin) deficiency (megaloblastic anemia) / pernicious anemia. /liver
diseases
Question: serum ferritin
Answer:
Tests for iron stores. As serum ferritin falls, TIBC rises, and serum iron levels will eventually fall.
Question: Anemia of chronic disease
Answer:
NORMOcytic anemia with ↓ serum iron, ↓ TIBC, and normal iron stores. Treat with epoetin and give an
iron supplement
Question: Schistocytes
Answer:
Associated with hemolytic uremia syndrome
Question: pernicious anemia
Answer:
Macrocytic anemia caused by vitamin B12 deficiency. B12 is essential to maturation of erythrocytes -
low levels will cause the RBC to expand. PPIs and histamine2 blockers can cause this.
Question: Increased homocysteine & methylmalonic acid level indicates ?
Answer:
B12 deficiency
, Question: increased homocysteine levels
Answer:
Folate deficiency
Question: Sperocytes
Answer:
Appear as spheres, lack central pallor, smaller diameter, indicate immune-mediated process - can be seen
after blood transfusion
Question: aplastic anemia
Answer:
a normocytic anemia characterized by the failure of bone marrow to produce red blood cells
Question: Low ferritin
Answer:
iron deficiency anemia
Question: Transferrin
Answer:
transports iron
Question: TIBC (total iron binding capacity)
Answer:
Available transferrin that is left unbound (Represents the "empty seats on a train"). When iron is low,
TIBC will be high. When iron is high, TIBC will be low
Question: MCHC (mean corpuscular hemoglobin concentration)
Answer:
32 - 36 g/dL Concentration of hemoglobin per RBC
Question: Alzheimer's disease
Answer:
Gradual onset with early memory impairment. Most common form of dementia. Cholinesterase
inhibitors for early treatment.
Question: Lewy body dementia
Answer:
