Absolute reticulocyte count (millions of cells/microL) = Reticulocytes (%) × RBC count (millions of cells/microL) |
Corrected reticulocyte count (%) = Reticulocytes (%) × (observed patient HCT [percent] ÷ 45* [percent]) or = Reticulocytes (%) × (observed patient hemoglobin [g/dL] ÷ 15* [g/dL]) |
Reticulocyte production index (no units) = Corrected reticulocyte count (%) ÷ maturation correction factor¶ (days) |
RBC: red blood cell; HCT: hematocrit.
* Calculations of corrected reticulocyte count use values based on reference ranges for adults (45% for HCT; 15 g/dL for hemoglobin); the values for children <12 years are lower, as discussed separately in UpToDate.
¶ Maturation correction (in days): HCT >35%: 1; HCT 26 to 35%: 1.5; HCT 16 to 25%: 2; HCT <15%: 2.5.آیا می خواهید مدیلیب را به صفحه اصلی خود اضافه کنید؟
