What is a normal UIBC level?
The short answer
A typical US lab prints a normal UIBC range of 120–380 µg/dL. That range exists to catch disease, not to describe your best.
Uibc has never come up on any of the shows we follow. So there's no number here.
What UIBC measures
The iron transport capacity still unused.
It is the other half of total capacity, and the two together show your iron status.
Checked against NCBI Bookshelf (StatPearls) — Iron-Binding Capacity.
Common questions
What is a normal UIBC level?
Most US labs print 120–380 µg/dL. Your report grades you against that range. It exists to catch disease, not to describe your best.
What does your UIBC number mean?
On a typical lab range, under 120 µg/dL is low, 120 to 380 is normal and over 380 is high. Your own report prints its range next to your number, and that is the one your lab uses. Nobody we follow has drawn a line inside that range.
What does the UIBC test measure?
The iron transport capacity still unused. It is the other half of total capacity, and the two together show your iron status.
Why is there no target here?
Because UIBC has never come up in anything we've watched. If that changes, it will be here.
