The question is not whether the test is accurate. It is whether knowing the number changes anything you would do.
Is a private blood test worth paying for?
Often it is not, and the reason is on i-screen's own terms page: none of its services are Medicare-rebatable or eligible for government subsidy. If a doctor believes a test is clinically indicated, that test is frequently bulk billed, and you would be paying between A$39 and A$1,099 for something available at no cost through the usual route. The cheapest first step is asking a GP whether the test you want is indicated.
What ordering directly buys is access and speed, not a better test. You choose the panel yourself, you need no referral, and results are typically back within 48 hours. That matters if your GP has declined to order something you want to see, if you are tracking a marker over time, or if waiting for an appointment is the obstacle. It does not make the result more meaningful than the same assay ordered by a doctor.
The case against is the one that applies to all screening outside a clinical indication. A number slightly outside a reference range, in a person with no symptoms, frequently leads to more tests, more cost and more worry without changing anything.
What A$20 off actually saves you
At the cheap end the code is substantial: A$20 off a A$39 test is about 51%. At the top of the catalogue it is about 2% of a A$1,099 panel, which is unlikely to be the thing that decides the purchase. Choose on what you need measured and treat the code as a deduction rather than a reason.
The code discounts your first test. It is not an ongoing saving, not a discount on a consultation, and not a subscription rate. It is typed at checkout: the click alone does nothing, for you or for us.
The tests and what they cost
A slice of the catalogue rather than all of it, chosen to show the range. i-screen lists 150+ tests in total. Read on 23 September 2026.
Diabetes HbA1c Test, A$39, 1 marker; Full Blood Count Test, A$39, 14 markers; Vitamin D Test, A$55, 1 marker; Iron Studies Test, A$59, 4 markers; Biological Age Test, A$59, 1 marker; Thyroid Function Test, A$69, 3 markers; Testosterone Test, A$69, 3 markers; Essential Health Test, A$140, 38 markers; Male Hormone Test, A$149, 11 markers; Metabolic Reset Test, A$249, 49 markers; Well Man Test, A$249, 51 markers; Well Woman Test, A$259, 52 markers; Comprehensive DNA Test, A$389, 129 markers; Men's Platinum Health Test, A$759, 155 markers; Women's Platinum Health Test, A$759, 155 markers; Men's Platinum Health & DNA Test, A$1,099, 284 markers; Women's Platinum Health & DNA Test, A$1,099, 284 markers.
That is a spread of about 28 times inside one provider, so "an i-screen test" is not one price and the brand name alone tells you nothing about what you will pay.
Who it suits, and who it does not
It suits someone with a specific marker in mind who wants it measured without a referral, and someone tracking the same panel over time. It suits less well anyone with symptoms, who is better served by a doctor who can examine them, and anyone whose test would be bulk billed on a GP's request.

How to get started
- 01
Choose your test
Pick from the catalogue, which runs A$39 to A$1,099. If you are unsure whether you need it, ask a GP first: an indicated test is frequently bulk billed.
- 02
Enter referlabs at checkout
The code takes A$20 off your first test. It is typed, not carried by the link, so entering it is the step that matters.
- 03
Give your sample
You attend an affiliated collection centre. No GP referral is needed to order or to attend.
- 04
Read your result
Results are typically available within 48 hours depending on the test, in an i-screen dashboard. Discuss anything that concerns you with a practitioner.
Should you use i-screen?
i-screen is a straightforward way to order pathology without going through a GP first, and the code referlabs takes A$20 off the first one. Whether it is worth paying for depends on a question the marketing does not ask: if a doctor considers the test clinically indicated, it is frequently bulk billed, and you would be paying for something available at no cost. Where it earns its keep is access and speed, not a better test.
- No referral, and results typically back within 48 hours
- A$20 off is about 51% of the cheapest test and about 2% of the dearest
- Nothing here is Medicare-rebatable, on i-screen's own terms
Frequently asked questions
What is the current i-screen discount code?+
The current i-screen discount code is referlabs. It takes A$20 off your first test and is entered at checkout. i-screen supplied it to Refer Labs directly and publishes it nowhere, confirmed 23 September 2026. It discounts the first test only: it is not an ongoing saving and not a discount on a consultation. Against a catalogue running A$39 to A$1,099, that is about 51% off the cheapest test and about 2% off the dearest.
How much do i-screen tests cost in Australia?+
Listed prices ran from A$39 for a single marker such as HbA1c or a full blood count, to A$1,099 for the 284-marker Platinum panel with DNA, read off i-screen's own catalogue on 23 September 2026. Mid-range annual panels such as the Well Man and Well Woman tests were A$249 and A$259. That is a spread of about 28 times, so "an i-screen test" is not one price.
Can you claim i-screen on Medicare?+
No. i-screen's own Terms and Conditions state that none of its services, including its clinical consultation services, are Medicare-rebatable or eligible for government subsidy, so the listed price is what you pay. A test a doctor considers clinically indicated is frequently bulk billed instead, which is why asking a GP first is the cheaper starting point for most people.
Do you need a GP referral for i-screen?+
No. i-screen states that no GP referral is needed: you order online, attend an affiliated collection centre to give the sample, and results are typically available within 48 hours depending on the test, in an i-screen dashboard. Read on i-screen's own site, 23 September 2026.
Who reviews an i-screen result?+
i-screen's terms describe AI-generated insights and interpretations, and say results flagged as outside expected ranges are routed to qualified health professionals, including doctors, nurses and dietitians, for review before they are released. i-screen also describes its services as wellness and educational, and states they are not a substitute for professional medical advice.
Does Refer Labs earn money from this page?+
Yes, and only through the code. i-screen gave us the coupon referlabs and there is no tracking link, so a reader who clicks through and buys without typing it earns us nothing. That is an unusual arrangement and worth stating plainly: we are paid when you use the discount, not when you click. It is also why this page tells you to ask a GP first, which is the advice that costs us money.
