The protein that carries iron in your blood — useful for evaluating iron transport and nutritional status. Transferrin is the primary protein responsible for transporting iron through the bloodstream. Measuring transferrin levels helps evaluate iron transport capacity and nutritional status. High transferrin with low iron saturation indicates iron deficiency, while low transferrin may suggest iron overload, liver disease, or chronic inflammation. **Clinical use:** Iron studies and anemia evaluation identify the most common cause of fatigue and exercise intolerance, and distinguish between iron-deficiency, inflammatory, and other types of anemia. ## Who should order it? Anyone with fatigue, low exercise tolerance, hair loss, or restless legs; menstruating individuals; vegetarians/vegans; pregnant or postpartum patients; and athletes monitoring iron status. ## Biomarkers measured - [Transferrin](https://www.test-well.com/biomarkers/transferrin) ## Price by lab | Lab | Test price | All-in (with $6 fee) | Notes | | --- | --- | --- | --- | | Quest Diagnostics | $23.99 | $29.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | | Labcorp | $24.99 | $30.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | | BioReference (NY & NJ) | $24.99 | $30.99 | New York and New Jersey orders route here automatically | Rhode Island is not served.
