What to bring

  • Pathology test request form completed by your doctor.

  • A valid Medicare card to ensure that your Medicare-covered testing can be bulk-billed back to Medicare.
You’ll need to bring photo ID if you’re having tests for one of the following reasons:
  • Immigration
  • Occupational Health
  • Parentage DNA
  • Insurance
  • Drug screening
  • Court ordered

What to do before your test

Your pre-testing instructions will depend on the test you’re having, but the most important thing you’ll need to do is drink plenty of water - unless your GP has given you a reason not to. This will make it easier for our team member to conduct your blood test.

In some cases, you may be required to fast before your test. This means you will not be able to eat or drink for a set of period of time. Fasting is necessary for some tests because some foods and drinks can affect your results.

Your doctor will let you know if you’ll need to fast prior to being tested. If your GP hasn’t mentioned this to you, it’s likely that you won’t need to.

A quick guide to fasting

  • Diabetics should not fast without prior medical advice.
  • Fasting means that you abstain from all food and fluids other than water for a period of 8-14 hours prior to your test.
  • Alcohol should not be consumed for 72 hours (3 days) prior to the test.
  • You should avoid smoking during the fasting period.
  • Do not fast for more than 14 hours prior to your testing.
  • Continue to take any medication unless advised otherwise by your doctor.
Tests that may require fasting include
  • Glucose levels
  • Lipids levels (cholesterol)
