|
Reduction in the number of rbc, hemoglobin or both in the circulating blood |
Anemia |
|
|
Anemia may be associated with |
-Decreased rbc production -inappropriate rbc loss -increase rbc destruction |
|
|
Basis of morphological classification |
MCV MCHC MCH |
|
|
Average mass of hemoglobin per rbc in a sample of blood |
MCH |
|
|
Measure of concentration of hemoglobin in a given volume of packed rbc. Defined as ratio of weight of hemoglobin to volume of rbc |

Acute hemorrhage |
|
|
Anemia manifested immediately until blood volume returns to normal |
Peracute hemorrhage |
|
|
