How Free Testosterone appears on your report
Look for Free Testosterone. The result is normally shown in pmol/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: collection time, sleep, illness, training, weight, medicines and changes in SHBG can move it. Read it with Total Testosterone and SHBG.
Free Testosterone range in Australia
Vector tracks Free Testosterone against an optimal range of 250–650 pmol/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.
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 Free Testosterone
A single marker rarely explains itself. These results are commonly interpreted together with Free Testosterone, and Vector keeps them within reach of each other as your record grows.
Tracking Free Testosterone over time
One Free Testosterone 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.

Common questions
What is a normal Free Testosterone range in Australia?
Australia has no nationally harmonised reference interval for Free Testosterone, 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 Free Testosterone against an optimal range of 250–650 pmol/L, which is deliberately tighter than a population reference interval.
What is the optimal Free Testosterone level?
Vector treats 250–650 pmol/L as the optimal range for Free Testosterone, with sex-specific bands of 250–650 for men and 3–25 for women. 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 Free Testosterone reported in on Australian pathology reports?
Free Testosterone is usually reported in pmol/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 Free Testosterone result?
Collection time, sleep, illness, training, weight, medicines and changes in SHBG can move it. Read it with Total Testosterone and SHBG.
