Transferrin saturation (TSAT) measures the amount of iron currently bound to transferrin in the blood.

Formula: TSAT = (Serum Iron / TIBC) × 100

Example: A patient has a Serum Iron of 90 μg/dL and a TIBC of 300 μg/dL.

"},"rowId":"c89cPML"},{"type":"text","key":"VGEPR","props":{"text":"

Step-by-step calculation:

"},"rowId":"BwAEvc6"},{"type":"text","key":"imS7x","props":{"text":"

Divide Serum Iron by TIBC: 90 / 300 = 0.30
Multiply by 100: 0.30 × 100 = 30%
The result indicates 30% saturation, which is within the normal range.

What does a low TSAT mean?

"},"rowId":"Ld3P9Pe"},{"type":"text","key":"y8lWp","props":{"text":"

A low TSAT (below 20%) often suggests iron deficiency, indicating there is more capacity to bind iron than there is iron available.

"},"rowId":"1XtkyfI"},{"type":"text","key":"AJ6WJ","props":{"text":"

What does a high TSAT mean?

"},"rowId":"LhJ3YrF"},{"type":"text","key":"dJkJ9","props":{"text":"

A high TSAT (above 50%) may indicate iron overload conditions like hemochromatosis or frequent blood transfusions.
