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.
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.
Anyone with fatigue, low exercise tolerance, hair loss, or restless legs; menstruating individuals; vegetarians/vegans; pregnant or postpartum patients; and athletes monitoring iron status.

A Transferrin test costs $23.99 at TestWell — $29.99 all-in when ordered alone, because the $6 lab processing fee is charged once per order, with no draw fee or physician fee added. Hospital outpatient labs typically bill around $90.00 self-pay for the same test, and often more. With insurance, what you pay depends on your deductible and your plan's negotiated rate; TestWell's price is fixed before the draw and is HSA/FSA-eligible.
