You finally get around to booking your blood test — and then the question hits: is my referral still valid? It matters, because an expired pathology referral means the lab can't process your test and Medicare won't pay its share.
Here's exactly how long blood test referrals last in Australia, when you need a new one, and what to do if yours has expired.
Referral expired or about to? An AHPRA-registered GP can issue a fresh pathology referral online — $25, same day.
Get a New Referral ($25)The Short Answer
A standard GP pathology referral in Australia is generally valid for 12 months from the date it's issued. That gives you a full year to get the tests done at any pathology collection centre.
But there are important exceptions — specialist referrals for pathology work differently, and repeat tests under the same referral have their own rules. Here's the full picture:
Key detail most people miss: for specialist-ordered pathology, the clock starts at your first test under the referral — not the issue date. For standard GP referrals, it generally runs from the date on the form.
When Might You Need a New Pathology Request?
The most common reason. If it's been more than 12 months since the referral was issued (or since your first specialist-ordered test), you'll need a new one.
If your health has changed since the original referral, your GP should decide which tests are actually appropriate now — not just re-run the old list.
Monitoring tests (thyroid, cholesterol, medication levels) typically need a fresh request each cycle unless your referral was written for repeats.
The issuing clinic can usually re-issue a copy. If not, a telehealth GP can assess you and issue a new referral the same day.
Why It Still Helps to Get Tests Done Promptly
Even inside the validity window, timing matters:
- Clinical relevance: results reflect your health on the day of the test. A referral written months ago may no longer match your current situation.
- Fasting requirements: some tests (lipids, glucose) need fasting — plan the timing when you book the collection centre.
- Medication timing: certain drug-level tests must be taken at a specific point in your dose cycle — check with your GP or the lab.
What to Bring to Your Blood Test
Make the lab visit quick and smooth by having ready:
- Your referral (digital is fine — a screenshot or email on your phone works at most collection centres)
- Your Medicare card
- Photo ID
- Any paperwork the requesting doctor gave you (e.g. fasting instructions)
Will I Need to Pay?
Most standard pathology tests ordered under a valid doctor's referral are Medicare-eligible, and the blood draw at major collection centres is usually bulk billed — meaning no out-of-pocket cost for the test itself.
Some specialty or non-Medicare-eligible tests carry a private fee — the collection centre will tell you before taking the sample. The referral consultation itself is separate: at NewTeleDoc Medical, an online pathology referral is a flat $25.

Frequently Asked Questions (FAQ)
Common questions about blood test referral validity in Australia.
How long is a blood test referral valid?
A standard GP pathology referral is generally valid for 12 months from the date it's issued. A GP can also mark a referral "indefinite" for ongoing chronic condition management.
Can I use an expired referral?
No — once a referral has expired, the lab can't process it and Medicare won't pay its share. The good news: a telehealth GP can issue a new referral online for $25, usually the same day.
Can I use the same referral for repeat blood tests?
Yes, if the referral was written for repeat testing (e.g. 3-monthly monitoring) — as long as each test happens within the referral's validity window.
What's an "indefinite" referral?
For ongoing chronic conditions, your GP can write a referral marked "indefinite," which doesn't expire. It's typically used for long-term monitoring of conditions like diabetes or thyroid disease.
Can I get a new blood test referral online?
Yes. An AHPRA-registered GP can assess you by phone or video and issue a digital pathology referral — $25 at NewTeleDoc Medical, same day. See our full guide: How to Get a Blood Test Referral Online in Australia.
