Term Description

Immature reticulocyte fraction (IRF) is index of erythropoietic activity. IRF is obtained by combining the sum of the medium (MFR) and high fluorescent reticulocyte (HFR) fractions.

Part Description

LP30869-9   Reticulocytes.immature
Immature reticulocytes, also called shift or stress cells, normally make up less than 5% of the total number of reticulocytes. They are released into the circulation during intense erythropoietic stimulation. Source: Regenstrief LOINC

Change Reason
Release 2.79: COMPONENT: Triggered by Coll w SCT: This is a specific fraction case where the denominator is percentage or /100. Because the logic is that the percentage piece is captured by Property: NFr (Numeric Fraction), and by Unit: %, therefore, it is redundant to include "100" in the component;
