Reticulocyte Hemoglobin
How much hemoglobin the newest red cells were built with — the earliest sign iron is running short. Lower results are the ones to watch. A common adult reference interval is 28–37 pg.
Typical adult range
- Reference interval
- 28–37 pg
- Often-cited tighter window
- 30–35 pg
Earliest sign of iron-restricted erythropoiesis. Your own lab's printed range is the one that applies to your result.
In more detail
Earliest signal that new red cells are being built iron-poor.
What commonly moves it
- Iron deficiencyLow stores or poor delivery limit red-cell production and thyroid conversion.
