How do I prepare for a pathology test? Do I need to fast?

Yes, fast for 8-12 hours before your test. Water is allowed and encouraged.

• Duration: 8-12 hours (overnight fasting works well)

• Water: Yes, please stay hydrated

• Black coffee/tea: No - these can affect results

• Medications: Continue as normal unless advised otherwise

• Timing tip: Book morning appointments to make fasting easier

• Photo ID

• Pathology referral (digital or printed)

• Medicare card (if applicable)

• List of current medications

• Eat normally until your fasting period begins

• Avoid alcohol for 24 hours

• Stay well-hydrated

• Get a good night's sleep

Most tests remain accurate - The 8-12 hour window is optimal, but slightly longer won't invalidate most results. A few extra hours of fasting won't ruin your test, but try to stick to the 8-12 hour window for optimal results. Your pathology provider can advise if your specific tests require stricter timing.

Some markers may shift slightly - Blood glucose may drop lower than baseline, cortisol levels might elevate (stress response)

• Up to 16 hours: Proceed with your test - results should still be reliable

• Over 16 hours:

  • Inform the pathology nurse about your fasting duration

  • They'll note it for the interpreting doctor

  • Still better to test than reschedule in most cases

• Feeling faint or dizzy: Have a small glass of water and sit down

• Diabetic or hypoglycemic: Don't extend fasting - stick to 8-12 hours

• Over 24 hours: Consider rescheduling as this may affect accuracy

• Set an alarm to remind yourself when to start fasting

• Book early morning appointments (7-9 AM) to minimize fasting discomfort

• Stay hydrated - water doesn't break your fast and prevents dehydration
