Anemia can contribute to: .....ANSWER..... coronary ischemia
Composition of blood .....ANSWER..... 5.5L total. 50-55% =
plasma; 90% water
Erythropoesis is stimulated by... .....ANSWER..... erythropoetin
Hemoglobin A .....ANSWER..... the majority of adult hemoglobin.
97% of circulating hemoglobin. 2 alpha and 2 beta chains.
HbA2 .....ANSWER..... minor adult hemoglobin. 2-3% of
circulating hemoglobin. 2 alpha and 2 delta chains.
,Page 2 of 95
Hemoglobin F .....ANSWER..... Fetal hemoglobin. 2 alpha and 2
gamma chains. Has a greater affinity for and more regularly
binds O2.
Anemia .....ANSWER..... a decrease in circulating red blood cells
in the body, as reflected by a reduction in hemoglobin,
hematocrit, and/or RBCs. Less than 14 in men and less than 12 in
women.
Normal RBC .....ANSWER..... 4.5-6
Normal Hemoglobin .....ANSWER..... >13 in men, >12 in women.
Normal HCT .....ANSWER..... 40-50in men; 35-45 in women.
usually 3x the hemoglobin count.
Reticulocyte count .....ANSWER..... Low (<0.5%) High (>2%) if
high, bone marrow is trying to compensate for loss in hgb or red
cells. problem exists outside of the bome marrow

MCV (mean corpuscular volume) .....ANSWER..... description of
the volume of an RBC. NOT DIAGNOSTIC
RDW (red cell distribution width) .....ANSWER..... 11.5-15 %;
index of variation in RBC size and shape. Indicates evolving
macro/microcytic anemia.
MCH (mean corpuscular hemoglobin) .....ANSWER..... commonly
used: 27 - 31 pg/ cell
Amount of hemoglobin per RBC
Microcytic anemia .....ANSWER..... Iron deficiency, thalassemia,
inflammation. low MCV <80. Low reticulocyte count.
Underproduction.
macrocytic anemia .....ANSWER..... Underproduction. B12
deficiency, Folic Acid Deficiency, Antimetabolite drugs. MCV >
100; low reticulocyte count
, Page 4 of 95
Normocytic Anemia .....ANSWER..... MCV 80-100; low
reticulocyte count; ex: dilutional/iatrogenic secondary to
phlebotomy.
Folate Deficiency Anemia .....ANSWER..... Macrocytic anemia;
poor intake; low retic, elevate MCV/MCH, thrombocytopenia ad
neutropenia, elevated homocysteine; low RBC folate. Eat orange
fruits! Never treat folate deficiency without testing for B12
deficiency - can worsen neurological symptoms specific to B12
deficiency
Vitamin B12 Deficiency .....ANSWER..... Macrocytic;
malabsorption; occurs when B12 is not released from food
proteins due to impaired digestion; Elevated MCV/Macrocytic;
Pernicious Anemia .....ANSWER..... lack of mature erythrocytes
caused by inability to absorb vitamin B12 into the bloodstream
Destruction (Hemolytic anemia) .....ANSWER..... anemia with
elevated reticulocytes; intrinsic and extrinsic
