What Reticulocyte Hemoglobin measures
The hemoglobin content of newly made red cells. It reflects iron available for red cell production over the past few days.
If your Reticulocyte Hemoglobin is low
A value below the range means new red cells are being made with too little iron, which shows up days to weeks before ferritin or hemoglobin change.
Commonly associated with
- Low iron available to the marrow
- Blood loss
- Inflammation limiting iron use
If your Reticulocyte Hemoglobin is high
A value above the range is uncommon and usually not read on its own; it is commonly seen with larger red cells.
Commonly associated with
- Larger red cells (high MCV)
- B12 or folate levels
Typical reference range
| Group | Typical range |
|---|---|
| Adults | 28 – 36 pg |
Typical adult values used by many US labs. Your own report prints the range your lab validated for its method, and that range is the one that counts. Labwise always uses the printed range first.
If it is within range
The hemoglobin content of your new red cells is within the range printed by your lab.
