How TIBC appears on your report

Look for Total Iron Binding Capacity (TIBC). The result is normally shown in µmol/L, next to the reference interval used by the laboratory that ran the test.

Note the collection date before you compare it with anything, along with the context that matters for this marker: iron status, inflammation, liver function, nutrition and protein levels can affect it.

TIBC range in Australia

Vector tracks TIBC against an optimal range of 45–72 µmol/L. Australia has no nationally harmonised reference interval for this marker, so the interval printed on your report varies with the laboratory and the assay it used.

No harmonised Australian interval exists for this marker — use the one printed beside your own result.

Vector’s optimal range is the band the app tracks against and the one printed in the doctor report. Why the two differ.

What to read alongside TIBC

A single marker rarely explains itself. These results are commonly interpreted together with TIBC, and Vector keeps them within reach of each other as your record grows.

Tracking TIBC over time

One TIBC result is a single point. Import the report into Vector, check the extracted value, unit and collection date, and it becomes the start of a series instead — with each later report adding a dated point you can actually compare against.

Further reading

TIBC is read the same way every other result on the report is. These two guides cover that method rather than this marker:

Common questions

What is a normal TIBC range in Australia?

Australia has no nationally harmonised reference interval for TIBC, so the range printed on your report varies with the laboratory and the assay it used — always read your result against the interval beside it. Vector tracks TIBC against an optimal range of 45–72 µmol/L, which is deliberately tighter than a population reference interval.

What is the optimal TIBC level?

Vector treats 45–72 µmol/L as the optimal range for TIBC. An optimal range is a target the app tracks against, not a clinical threshold, and it can differ from the interval your laboratory prints.

What unit is TIBC reported in on Australian pathology reports?

TIBC is usually reported in µmol/L on Australian pathology reports. The performing laboratory prints a reference interval in the same unit beside the result, and that interval is the one that governs your individual result.

What can change your TIBC result?

Iron status, inflammation, liver function, nutrition and protein levels can affect it.
