Traditional GP testing usually covers the basics like full blood count, lipids, liver function, and maybe iron if you ask. But that is where it stops.
If you want advanced biomarkers, detailed hormone analysis, or performance-based testing, you are often told:
“You don’t meet Medicare criteria.”
“It’s not clinically indicated.”
“We will test one marker, but not the rest.”
This leaves people frustrated and without answers.
With MediTests, you can finally get the deeper insights you are looking for without waiting, without begging for referrals, and without being restricted by Medicare rules.
✔ No GP consult or referral needed
✔ Choose any test you want
✔ 3,000 plus collection centres nationwide

Below are the 10 most in-demand biomarkers Australians are ordering privately right now and why your GP often won’t test them.
One of the most important markers for heart disease risk and rarely included in GP lipid panels.
Why GPs don’t test it: Not covered by Medicare unless you have very specific risk factors.
Why you should: ApoB gives a far more accurate picture of cardiovascular risk than LDL alone.
A direct marker of inflammation and long-term disease risk.
Why GPs don’t test it: Considered “nonessential” for general check-ups.
Why you should: High inflammation affects energy, weight, recovery, and long-term health.
Measures omega-3 levels inside your red blood cells.
Why GPs don’t test it: Not part of standard pathology and considered a lifestyle test.
Why you should: Strong omega-3 levels are linked to better cardiovascular health, mental health, and metabolic function.
Your stress hormone, closely linked to fatigue, anxiety, weight, and sleep.
Why GPs don’t test it: Harder to justify under Medicare without very specific symptoms.
Why you should: Chronically high cortisol impacts recovery, training performance, mood, and metabolism.
Especially important for women, athletes, and people dealing with ongoing fatigue.
Why GPs limit it: Often only test haemoglobin unless you specifically ask.
Why you should: Low ferritin leads to low energy, low oxygen capacity, and poor training performance.
Crucial for understanding how your hormones actually function.
Why GPs don’t test it: Requires specific symptoms or fertility investigations to qualify under Medicare.
Why you should: SHBG determines how much testosterone or oestrogen your body can use. It is essential for understanding hormone balance.
One of the most requested private tests in Australia.
Why GPs often refuse: Must meet Medicare criteria for suspected low testosterone.
Why you should: Low testosterone affects mood, libido, strength, motivation, and overall performance.
Essential for women’s hormone health and increasingly tracked by men.
Why GPs limit it: Typically only tested during fertility or reproductive investigations.
Why you should: Estradiol influences mood, weight, cycle health, bone density, and energy levels.
The missing piece of the thyroid puzzle.
Why GPs don’t test it: Medicare does not consider rT3 clinically necessary except in rare cases.
Why you should: rT3 reveals how stress, illness, or chronic fatigue may be slowing your metabolism.
Arguably the most important early-warning marker for metabolic health.
Why GPs don’t test it: They usually rely on glucose or HbA1c, which can appear normal even when insulin is elevated.
Why you should: High fasting insulin contributes to stubborn weight gain, cravings, fatigue, and early metabolic dysfunction.

Most GPs follow Medicare guidelines and can only order certain tests if you meet very specific criteria. Many advanced biomarkers are not routinely funded or considered “clinically necessary,” which limits what they can order.
