What do your hemoglobin levels mean?
The short answer
Nobody we follow has said what your hemoglobin should be. It comes up on the shows, but never with a number.
Your lab prints 12–15.5 g/dL. That range exists to catch disease, not to describe your best.
Labs print different ranges by sex: about 12–15.5 g/dL for women and 13.5–17.5 for men.
What hemoglobin measures
The protein inside red blood cells that carries oxygen.
It is the direct readout for anaemia. It falls only after your iron stores have already run down.

Common questions
What is a normal hemoglobin level?
Most US labs print 12–15.5 g/dL. Your report grades you against that range. It exists to catch disease, not to describe your best. Labs print different ranges by sex: about 12–15.5 g/dL for women and 13.5–17.5 for men.
What does your hemoglobin number mean?
Under 12 g/dL, your report marks it low. Between 12 and 15.5 it prints as normal. Over 15.5, your report marks it high. Nobody we follow has drawn a line inside that range. Labs print different ranges by sex: about 12–15.5 g/dL for women and 13.5–17.5 for men.
What does the hemoglobin test measure?
The protein inside red blood cells that carries oxygen. It is the direct readout for anaemia. It falls only after your iron stores have already run down.
Why is there no target here?
Because nobody we follow has named a number for hemoglobin. If that changes, it will be here.
