Blood count
Reticulocytes Absolute
Brand-new red cells released by the marrow. Near-zero means the marrow is not answering the call for more blood. Lower results are the ones to watch. A common adult reference interval is 20–110 K/uL.
Typical adult range
- Reference interval
- 20–110 K/uL
- Often-cited tighter window
- 30–80 K/uL
Standard adult laboratory reference interval. Your own lab's printed range is the one that applies to your result.
In more detail
Near-zero means the marrow is not responding to anemia.
What commonly moves it
- Iron deficiencyLow stores or poor delivery limit red-cell production and thyroid conversion.
- Kappa/Lambda Ratio
- Plasma-cell / paraprotein activityClonal light-chain production raises globulin and can suppress marrow output.
