Key facts

• Reticulocyte production index
• Reticulocytes/Erythrocytes^^hematocrit adjusted
• The reticulocyte production index also called the corrected reticulocyte "count" (it is really a percentage, adjust the observed count for the degree of anemia based on the hematocrit using the formula Recticulocyte index= Reticuloctye% *( Hct(observed)/45) where 45 is taken to be the "standard" hematocrit Reticulocyte production index= Reticulocyte index X correction factor" where correction factor is applied as follows HCT Correction factor 36-45 1.0 26-35 1.5 16-25 2.0 < 15 2.5
