Term Description

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
