**  The reticulocyte count is corrected using the PCV if the RBC is not known.

Corrected = 5.7%  X  Patient's PCV
                 normal K9 PCV
=

5.7%  X    29
                  45
=

3.7%


**  If the RBC count is known, an absolute reticulocyte count is determined.   

Absolute reticulocyte  count = Retic % of RBC
= 5.7% of 4.62 M/microliter
= 0.057 X 4.62 M/microliter
= 0.26 M/microliter
= 263,300 /microliter
