What is a normal transferrin level?
The short answer
A typical US lab prints a normal transferrin range of 200–360 mg/dL. That range exists to catch disease, not to describe your best.
Nobody we follow has said what your transferrin should be. It comes up on the shows, but never with a number.
What transferrin measures
The protein that carries iron through your blood.
Your body makes more of it when iron is short, so it moves opposite to your stores.

What does your transferrin number mean?
On a typical lab range, under 200 mg/dL is low, 200 to 360 is normal and over 360 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.
