Transferrin Saturation

CalculatedFiller

Serum iron as a percentage of your total iron binding capacity.

Calculated from two results already reported above it.

This one isn’t a test

Transferrin Saturation = (Serum Iron ÷ TIBC) × 100

No extra sample was taken for this and no extra assay was run. It is arithmetic on numbers already on your report — but it still adds a line to the advertised test count.

Computed from Serum Iron and TIBC.

That does not make the number useless — eGFR is calculated and doctors act on it every day. It means it should not be counted as a separate test when you are comparing what a package costs.
