How Phosphate appears on your report

Look for Phosphate. The result is normally shown in mmol/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: kidney function, vitamin D, parathyroid hormone, nutrition and some medicines can affect it.

Phosphate range in Australia

The harmonised Australian adult reference interval for Phosphate is 0.75–1.5 mmol/L. Vector tracks against the same range.

Adult0.75
1.5mmol/L
Nationally harmonised

Harmonised across participating Australian and New Zealand laboratories, so these numbers do not change between providers.

Vector’s optimal range is the band the app tracks against and the one printed in the doctor report. Why the two differ. Reference interval source: AACB / RCPA Common Reference Intervals.

What to read alongside Phosphate

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

Tracking Phosphate over time

One Phosphate 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

Phosphate 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 the optimal Phosphate level?

Vector treats 0.8–1.5 mmol/L as the optimal range for Phosphate. For this marker Vector's optimal range matches the harmonised Australian reference interval, so clearing the laboratory range and sitting in Vector's target are the same thing.

What is the normal range for Phosphate in Australia?

The harmonised Australian adult reference interval for Phosphate is 0.75–1.5 mmol/L. This interval is harmonised across participating Australian and New Zealand laboratories, so it does not change between providers.

What unit is Phosphate reported in on Australian pathology reports?

Phosphate is usually reported in mmol/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 Phosphate result?

Kidney function, vitamin D, parathyroid hormone, nutrition and some medicines can affect it.
