How hs-CRP appears on your report
Look for High-Sensitivity C-Reactive Protein (hs-CRP). It may also be printed as hs-CRP. The result is normally shown in mg/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: colds, infection, injury, hard exercise, smoking, gum inflammation, weight and metabolic health can move it. It is most useful as a baseline when you are well.
hs-CRP range in Australia
Vector tracks hs-CRP against an optimal range of 0.0–1.0 mg/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 hs-CRP
A single marker rarely explains itself. These results are commonly interpreted together with hs-CRP, and Vector keeps them within reach of each other as your record grows.
Tracking hs-CRP over time
One hs-CRP 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 hs-CRP range in Australia?
Australia has no nationally harmonised reference interval for hs-CRP, 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 hs-CRP against an optimal range of 0.0–1.0 mg/L, which is deliberately tighter than a population reference interval.
What is the optimal hs-CRP level?
Vector treats 0.0–1.0 mg/L as the optimal range for hs-CRP. 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 hs-CRP reported in on Australian pathology reports?
hs-CRP is usually reported in mg/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 hs-CRP result?
Colds, infection, injury, hard exercise, smoking, gum inflammation, weight and metabolic health can move it. It is most useful as a baseline when you are well.
What else is hs-CRP called?
High-Sensitivity C-Reactive Protein (hs-CRP) may also appear as hs-CRP on a pathology report. Laboratories differ in the label they print, which is why Vector matches on several names for the same analyte.
