Anemia
Definition
Hematocrite = 42%,
Hemoglobin = 14 in males and
Hematocrite = 37%
Hemoglobin 12 in females
Types
The normal physiological reaction to anemia is to
increase bone marrow production of red cells. This is manifested by an
increased reticulocytic count (a normal reaction).
In its simplest form anemia is ether:
This means that the bone marrow is not reacting as
it should. This is the case when anemia is caused by bone marrow
dysfunction or inability to produce red cells due to inadequate
resources (e.g. iron).
This means that the patient has a healthy bone
marrow which is reacting to the anemia as it should but not able to
compensate it. Anemia here is caused by factors outside the bone
marrow such as blood loss or destruction (hemolysis).
Absolute
reticulocyte count = % of reticulocytes x RBC count and should be
</= 100,000
