Why doctors use it

Doctors use this test alongside symptoms, history and other findings. A single result is not read on its own.

Before your test

01No special preparation unless your doctor advises otherwise.

Sample collection experience

A trained professional cleans the site, draws the sample into a labelled tube, and the sample is barcoded before transport to the laboratory.

Understanding your report

Your report lists each parameter with its measured value, unit and reference range. Reference ranges vary by age, sex, method and laboratory, so compare values only against the range printed on your own report. A value outside the range is a prompt for a conversation with your doctor, not a diagnosis on its own.
