Iron status

Iron (serum)

Iron (serum) is tracked as part of iron status. Lower results are the ones to watch. A common adult reference interval is 50–170 ug/dL.

Typical adult range

Reference interval
50–170 ug/dL
Often-cited tighter window
70–130 ug/dL

Standard adult laboratory reference interval. Your own lab's printed range is the one that applies to your result.

What commonly moves it

  • Iron deficiencyLow stores or poor delivery limit red-cell production and thyroid conversion.
  • Absorption problemGut permeability or low stomach acid limits iron, B12 and fat-soluble uptake.

What it can affect downstream

These are commonly described physiological relationships, shared for education. They are not a diagnosis and cannot account for your medications, history, or symptoms — discuss your results with a licensed clinician.
