What is the number 1 cause of anemia?
Iron deficiency
Etiology of Anemia (2)
decrease in RBC production or faulty RBC production
increased RBC destruction

Pallor
Fatigue
Weakness
Vertigo
Signs + symptoms Acute anemia
Dizziness
SOB (Dyspnea)
Tachycardia
Signs + symptoms low B12 anemia
decrease in memory, gait, vibratory sensory
Know that normal MCV = ? Normal MCH= ? Retic count = ? Serum iron= ? Ferritin= ? MA= requires ?
Know that normal MCV = 80 Normal MCH= 32 Retic count 1% Serum iron= 50 Ferritin= 30 MA= requires b12 in order to break down if not it will float in your body at high levels
Recommended daily intake for healthy patients?
in order of who needs the most.
Prego: 30 mg/day
Blood donors: 20 mg/day
Vegans: 16 mg/day
Iron stores?
Ferritin
Hemoglobin
Amount of Hgb per unit volume of blood
Hematocrit
Actual volume of RBCs/unit of whole blood (%)
MCV- Mean Corpuscular Volume
Average volume of RBC
Determines whether microcytic, macrocytic, or normocytic
Mean Corpuscular Hemoglobin Concentration (MCHC)
Hb/Hct
Weight of Hgb per volume of cells
Low MCHC= hypochromia
Mean Corpuscular Hemoglobin (MCH)
% volume of Hb in an RBC
Iron supply
Reticulocyte count (Retic)
Production of IMMATURE RBCs
What is an indication of decreased RBC production?
Decrease Retic
What is an indication of hemolysis or blood loss?
Elevated retic
Iron studies (panel) consist of what? (5)
Order if microcytic, hypochromic anemia suspected
Serum iron- measure the iron floating around in blood
Total iron binding capacity (TIBC)- bound iron
Transferrin saturation (Tsat)-
Serum ferritin- iron stores
What causes pernicious anemia?
Lack of IF which increases B12 absorption from food.
Which type of deficiency is associated with pernicious anemia?
B12-deficiency
What is a schilling test associated with?
Pernicious anemia- lack of IF in GI tract
What should be ruled out in Folate Deficiency and why?
B12 so that hematologic abnormalities can be addressed before neurological abnormalities
When are ESAs - EPO stimulating agents used in anemia?
During Anemia inflammation to prevent transfusion
