Includes:

Reticulocyte count; Reticulocyte count; Immature Retic Fraction (IRF); Reticulocyte Hemoglobin (RET-He)

Turnaround Time:

Urgent and Routine: 45 Minutes 

Test Schedule:

Monday through Friday 6:30 am to 6:00 pm.
Saturday 7:00 am to 5:00 pm.
Sunday 7:30 am to 4:00 pm.

Interpretation:

Reticulocyte Hemoglobin Equivalent (RET-He): The measurement of reticulocyte hemoglobin content is a direct assessment of the incorporation of iron into erythrocyte hemoglobin and thus a direct estimate of the functional availability of iron into the red blood cell. Low values indicate inadequate iron supply relative to demand. Referenced from: Brugnara, C., Schiller, B., Moran, J. (2006). Reticulocyte hemoglobin equivalent (Ret He) and assessment of iron-deficient states, Clinical Laboratory Hematology, 18:303-308.
