Transferrin Unit Converter
Transferrin (Tf) is the principal iron-transport protein in plasma. It binds ferric iron (Fe3+) absorbed from the diet or released from stores and delivers it to the bone marrow for erythropoiesis.
Transferrin levels are a key component of the Iron Panel. It acts as a **negative acute-phase reactant**, meaning levels decrease during inflammation, liver disease, or malnutrition, and increase during iron deficiency. This converter facilitates switching between standard mass units (mg/dL) and SI molar units (μmol/L).
Mass Units
StandardMilligrams per deciliter (Common US Unit).
SI Units / Molar
Micromoles per liter (SI Standard).
Clinical Context
Reference Ranges (Adults):
• 200 – 360 mg/dL (2.0 – 3.6 g/L).
Interpretation:
• High: Iron Deficiency Anemia (body attempts to capture more iron), Pregnancy, Estrogen therapy.
• Low: Iron Overload (Hemochromatosis), Liver disease, Malnutrition (protein deficiency), Chronic Inflammation.
Conversion Logic:
Molecular Weight of Transferrin: ~79,570 Da (79.57 kDa).
1 mg/dL ≈ 0.126 μmol/L.
1 μmol/L ≈ 7.957 mg/dL.

Frequently Asked Questions
They are closely related. TIBC (Total Iron Binding Capacity) measures the capacity of transferrin to bind iron. Transferrin concentration can be estimated from TIBC: Transferrin = TIBC × 0.70.
It is the percentage of transferrin binding sites occupied by iron. Calculated as: (Serum Iron / TIBC) × 100.
