What do your transferrin levels mean?
The short answer
Nobody we follow has said what your transferrin should be. It comes up on the shows, but never with a number.
Your lab prints 200–360 mg/dL. That range exists to catch disease, not to describe your best.
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.
