Transferrin Saturation

Iron status from serum iron and TIBC.

Education and reference only. Not a substitute for clinical judgement, local policy or product labelling. Always verify before clinical use. Values are calculated in your browser and never stored.

When to use

Use to assess iron status — low suggests iron deficiency; high suggests iron overload (e.g. haemochromatosis).

Why use

It is a core part of the iron-study interpretation.

Critical actions

Use the same units for iron and TIBC. Interpret with ferritin and the clinical picture.

Evidence & references
