Assessment of iron transport capacity in blood.
Serum transferrin test measures the level of transferrin, a protein produced by the liver that binds and transports iron in the bloodstream to tissues that need it; especially the bone marrow for red blood cell production. It is useful for evaluating iron deficiency, iron overload disorders, and nutritional status, and may support diagnosis of anaemia and chronic diseases.

How our test process works!
Overview:
-
Purpose: Measures the level of transferrin, a protein that binds and transports iron in the blood.
-
Clinical Use: Helps assess iron status, detect iron deficiency anemia, chronic infections, liver disease, and malnutrition.
Risk Assesment :
-
Risks: Minimal; standard blood draw risks (bruising, slight pain, infection).
-
Precautions: Inform lab if on iron supplements, oral contraceptives, or have liver disease.
Normal Range:
-
Adults: ~200–360 mg/dL (may vary slightly by lab)
-
Note: Levels can be influenced by pregnancy, liver disease, and nutritional status.
Interpretation:
-
High Transferrin: Suggests iron deficiency, pregnancy, oral contraceptive use.
-
Low Transferrin: Seen in malnutrition, chronic illness, liver disease, nephrotic syndrome.
-
Combined Assessment: Often interpreted with serum iron, ferritin, and TIBC (Total Iron Binding Capacity).
Sample Type:
-
Specimen: Blood (serum)
-
Collection: Venipuncture
-
Fasting: Not strictly required
