What is Hb/Hemoglobin?

Updated 4 weeks ago by Michelle Pool

Hb stands for hemoglobin, which is the protein molecule in red blood cells that carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues back to the lungs.

A low hemoglobin level is referred to as anemia or low red-blood count.

Hb is essentially used as a measure of how much oxygen you are able to carry in your red blood cells.
