Briefly explain the procedure for a reticulocyte count

After preparing a blood smear and staining it, focus on the monolayer. Count 1000 RBCs noting the number of aggregated reticulocytes seen.

Formula: Calculate corrected reticulocyte count

Observed reticulocyte * observed PCV/ normal mean PCV for species = corrected reticulocyte %

What is the mean PCV for canines

45%W

What is the mean PCV for felines?

35%
