Use Corrected Retic Percent when you need to correct the reticulocyte percent for anemia by multiplying by the patient to normal hematocrit ratio with a reference normal hematocrit of 45 percent. Enter Reticulocytes, Patient hematocrit, and Normal hematocrit using the definitions and units below so the result can be reproduced.

Reticulocytes

A finite measured or assumed value greater than or equal to 0, expressed in %.

Patient hematocrit

A finite measured or assumed value less than or equal to 100, expressed in %.

Normal hematocrit

Reference normal hematocrit.

The published tool contract uses this rule: Correct the reticulocyte percent for anemia by multiplying by the patient to normal hematocrit ratio with a reference normal hematocrit of 45 percent.

Corrected reticulocytes

The calculated corrected reticulocytes in %.

A ratio or percentage can conceal the scale of its numerator and denominator and becomes sensitive to measurement error when the denominator is small.

Retain the original Reticulocytes, Patient hematocrit, and Normal hematocrit 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. RPI Corrected provides another view by helping you compute the corrected reticulocyte production index as the reticulocyte percent divided by a maturation factor and scaled by the patient to normal hematocrit ratio.

• 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.

• RPI Corrected

  Compute the corrected reticulocyte production index as the reticulocyte percent divided by a maturation factor and scaled by the patient to normal hematocrit ratio.

• Absolute Reticulocytes

  Compute absolute reticulocyte count from reticulocyte percentage and RBC count.
