Clinicians order transferrin to evaluate tiredness, anemia, or suspected iron deficiency. It helps tell low iron apart from inflammation-related changes and is used to track recovery. Results guide next steps such as checking ferritin, serum iron, and a full blood count. You can test this marker with Aniva across Germany and Finland.

High: Often seen when iron stores are low or demand is higher, such as in iron deficiency or pregnancy. This may go along with low transferrin saturation.
Low: Can occur with inflammation, liver problems, poor protein intake, or kidney protein loss. Pair with ferritin and serum iron to clarify your iron status. A simple step is to review supplements, hormones, and any recent illness before retesting.
Common factors that can skew results include iron supplements or recent transfusion, estrogen therapy or pregnancy (can raise transferrin), androgens (can lower), and acute illness or inflammation (often lowers). Severe liver disease, dehydration, heavy exercise, and high-dose biotin supplements may also affect some methods.
Special situations: confirm or adjust interpretation during pregnancy, active infection, or with liver or kidney conditions, and always review alongside ferritin and serum iron.
What does a transferrin result mean? Higher levels often suggest low iron stores or increased demand. Lower levels can reflect inflammation, liver issues, or low protein intake.
Do I need to fast before this test? No. Fasting is not required for a transferrin test.
What can affect my result? Iron pills or recent transfusion, estrogen or androgen therapy, pregnancy, acute illness, dehydration, heavy exercise, and high-dose biotin can all shift results.
How often should I test transferrin? Test when checking anemia or iron balance, and recheck as your clinician advises, often after weeks to months if monitoring.
How long do results take? Most labs report results within 1–3 business days.
What should I discuss with my clinician? Share symptoms, diet, possible blood loss, medications, and supplements. Ask whether to add ferritin, serum iron, and a CBC for a clearer picture.
