What is erythrocytosis?
Increase number of RBC
Erythrocytosis refers to an increase in the number of red blood cells (RBC) in the bloodstream.
What does polycythemia refer to?
Increase number of RBC
Polycythemia is often used interchangeably with erythrocytosis, indicating an increased concentration of red blood cells.
What is anisocytosis?
Varying size
Anisocytosis is a condition characterized by the presence of red blood cells of unequal sizes.
What is poikilocytosis?
Varying shape
Poikilocytosis refers to the presence of red blood cells of various shapes.
What is reticulocytosis?
Immature erythrocyte
Reticulocytosis indicates an increase in reticulocytes, which are immature red blood cells.
What are thalassemias?
Hemoglobinopathies
Thalassemias are inherited blood disorders affecting hemoglobin production, classified as hemoglobinopathies.
What is morphological anemia?
Abnormalities in red blood cell morphology
Morphological anemia encompasses various types of anemia identified by abnormalities in red blood cell morphology.
What is normocytic normochromic anemia?
Aplastic anemia.
Anemia with normal size and color of RBC
Normocytic normochromic anemia is characterized by red blood cells that are normal in size and hemoglobin content.
What is microcytic hypochromic anemia?
Iron deficiency anemia
Microcytic hypochromic anemia is typically caused by iron deficiency, resulting in smaller and paler red blood cells.
What is macrocytic normochromic anemia?
Macrocytic Hypochromic
Megaloblastic anemia
Macrocytic normochromic anemia is often associated with megaloblastic anemia, where red blood cells are larger than normal but have normal color.

45-70%
What is the normal percentage range for Eosinophils?
2-8%
What is the normal percentage range for Basophils?
0.5-1%
What percentage of white blood cells do Monocytes typically represent?
5-10%
What percentage of white blood cells do Lymphocytes typically represent?
20-30%
What is the average life span of Neutrophils?
2-4 days
What is the average life span of Eosinophils?
8-12 days
What is the average life span of Basophils?
2-3 days
What is the average life span of Monocytes?
12-15 days
What is the average life span of Lymphocytes?
1-2 days
