How Fibrinogen appears on your report
Look for Fibrinogen. The result is normally shown in g/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: infection, inflammation, injury, smoking, pregnancy, oestrogen and metabolic health can affect it.
Fibrinogen range in Australia
Vector tracks Fibrinogen against an optimal range of 2.0–4.0 g/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 Fibrinogen
A single marker rarely explains itself. These results are commonly interpreted together with Fibrinogen, and Vector keeps them within reach of each other as your record grows.
Tracking Fibrinogen over time
One Fibrinogen 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 Fibrinogen range in Australia?
Australia has no nationally harmonised reference interval for Fibrinogen, 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 Fibrinogen against an optimal range of 2.0–4.0 g/L, which is deliberately tighter than a population reference interval.
What is the optimal Fibrinogen level?
Vector treats 2.0–4.0 g/L as the optimal range for Fibrinogen. 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 Fibrinogen reported in on Australian pathology reports?
Fibrinogen is usually reported in g/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 Fibrinogen result?
Infection, inflammation, injury, smoking, pregnancy, oestrogen and metabolic health can affect it.
