Use Absolute Reticulocytes when you need to compute absolute reticulocyte count from reticulocyte percentage and RBC count. Enter Reticulocyte percentage and Red blood cell count using the definitions and units below so the result can be reproduced.

Reticulocyte percentage

A finite measured or assumed value from 0 through 100, expressed in %.

Red blood cell count

A finite measured or assumed value greater than or equal to 5e-324, expressed in million/µL.

The published tool contract uses this rule: Compute absolute reticulocyte count from reticulocyte percentage and RBC count.

Absolute reticulocytes

The calculated absolute reticulocytes in cells/µL.

A ratio or percentage can conceal the scale of its numerator and denominator and becomes sensitive to measurement error when the denominator is small. Reticulocyte percentage must remain between 0 and 100.

Retain the original Reticulocyte percentage and Red blood cell count values and their units alongside the result. ARC From Percent is useful when you instead need to compute the absolute reticulocyte count in thousands per microlitre as the reticulocyte percent times the RBC count in millions per microlitre times ten. ANC Calculator provides another view by helping you compute absolute neutrophil count from white blood cell count and neutrophil percentage.

• ARC From Percent

  Compute the absolute reticulocyte count in thousands per microlitre as the reticulocyte percent times the RBC count in millions per microlitre times ten.

• ANC Calculator

  Compute absolute neutrophil count from white blood cell count and neutrophil percentage.

• Corrected Retic Percent

  Correct the reticulocyte percent for anemia by multiplying by the patient to normal hematocrit ratio with a reference normal hematocrit of 45 percent.
