Hemoglobin (Bld)
Hemoglobin is the protein in your red blood cells that carries oxygen. It’s one of the most direct markers for how well your body can deliver oxygen to your muscles, brain, and organs. Low hemoglobin means less oxygen-carrying capacity—often due to iron, B12, or folate deficiencies. High levels can reflect dehydration, altitude adaptation, or elevated erythropoietin. This is a key marker for endurance, fatigue, and performance.
