What does reticulocyte count measure? How rapidly bone marrow is producing reticulocytes (immature RBCs)
What is a normal reticulocyte count? Normal: <1.5%
What does it mean if it's elevated >2%? >2% = acute bleeding or chronic blood loss
How would rapid blood loss or hemolytic disease affect Would increase.
reticulocyte count? Also initially seen at elevated altitudes.
What would a low reticulocyte indicate? What count Low count may indicate decreased production of RBCs by bone marrow (possible
possibly cause this? aplastic anemia).
Possible causes:
-Exposure to radiation
-Chronic infection
-Certain medications
What does mean corpuscular volume (MCV) measure? The average volume of RBCs in a specimen - (Or the average size of the RBCs??)
What would elevate or decrease MCV?
Elevation or decrease will occur in accordance to the average red cell size.
Low MCV = Microcytic anemia
Normal MCV = Normocytic anemia
High MCV = Macrocytic anemia
What is a normal MCV range? 80-100 fL
What are some causes of microcytic anemia? -Thalassemia
-Iron deficiency
-Anemia or chronic disease
What are some causes of macrocytic anemia? -B12/folate deficiency
-Alcohol use
-Chronic liver disease
-Drugs
-Reticulocytosis
-Aplastic anemia
-Hypothyroidism
What is red cell distribution width (RDW) The difference in size between the smallest and largest RBCs in a sample.
What is the average diameter for a red cell? 6-8 micrometers
