Your Guide to Navigating the Healthcare System

If you have new or unexplained symptoms, suspected disease or a medical concern, your primary care physician should generally be your first point of contact.

Your physician can assess whether laboratory testing, imaging, medical treatment or referral to a specialist is appropriate.

Many basic laboratory tests included in private health check-ups may already be available through your physician when medically indicated, either through public healthcare or health insurance.

Before paying privately, ask whether the same investigation can appropriately be carried out through the healthcare system you already have access to.

If yes, start there. If your physician does not consider a particular test medically indicated, or the investigation falls outside conventional diagnostic pathways, you can then decide whether private testing offers information worth paying for.

Don't pay twice for healthcare you may already have access to.

A private health assessment is not advanced simply because it includes blood tests.

Basic blood tests are important. They are commonly used to identify, rule out or monitor disease and common health abnormalities. A standard blood test does not become more sophisticated because it is packaged into a private health check or presented in an impressive dashboard.

Private healthcare becomes valuable when it adds another layer.

• More time to understand a complex health history
• Preventive and risk-focused assessment
• Deeper interpretation of existing results
• Connecting patterns across symptoms, history and laboratory data
• Specialised investigations that are not routinely available
• Translating findings into a practical strategy

Depending on the individual, specialised investigations may include more detailed assessment of nutrient status, environmental or toxicant exposures, genetics, metabolic patterns or other biological markers.

Advanced testing is not automatically better testing. Every test should answer a relevant question and ideally have the potential to change what you do next.

• 1. Can I appropriately get this through my physician or existing healthcare coverage?
• 2. Why is this test relevant to my symptoms, history or risk profile?
• 3. What information will it provide that we do not already have?
• 4. Could the result meaningfully change my recommendations or next steps?
• 5. Who will interpret the result, and what qualifies that person to do so?

More biomarkers do not automatically mean better healthcare. The value lies in selecting the right investigation for the right reason.

Before taking advice, ask a simple question: What is this person actually educated and trained to advise me on?

Medical advice

If you need diagnosis, prescription medication or medical advice, seek an appropriately qualified and licensed medical doctor or another regulated healthcare professional practising within their professional scope.

Nutrition advice

If you need individualised nutrition advice, look for substantial formal education in human nutrition, such as a Registered Dietitian or a professional with a bachelor's or master's degree in human nutrition or another directly relevant discipline.

A short nutrition certification is not equivalent to several years of university-level education in nutrition, physiology and biochemistry.

Advanced testing and biological medicine

If someone offers advanced laboratory testing, biological medicine, integrative healthcare or functional medicine, investigate their specific postgraduate or continuing education in the field they are advising you on.

This applies regardless of whether the person originally trained as a physician, dietitian, nutrition professional or another healthcare practitioner.

"Functional medicine" is not, by itself, a professional qualification.

The term tells you very little about someone's foundational education, professional scope or level of specialist training.

You may find highly educated healthcare professionals who have undertaken years of additional training in functional, biological or integrative approaches.

You may also encounter coaches, influencers or practitioners using the same terminology despite having limited formal education in human health sciences or only brief certification-based training.

The label is not the credential. Look at the person behind it.

• What was their foundational education?
• What additional training have they completed?
• How extensive was that training?
• Does their education directly relate to the advice they are giving you?

A medical degree provides a substantial foundation in medicine, but it does not automatically make every doctor an expert in clinical nutrition, environmental toxicology or specialised functional testing.

Likewise, being a Registered Dietitian or holding a degree in nutrition does not automatically establish expertise in toxicology, genetics, biological medicine or advanced laboratory interpretation.

Degrees such as MD, RD, bachelor's and master's qualifications provide the scientific and professional foundation. Specialist work requires relevant further education on top of that foundation.

If someone advises extensively on toxicology, genetics, advanced nutrition, biological medicine or specialised laboratory assessment, look for meaningful additional education in that specific area.

Foundational education + relevant advanced training. Look for both.

Continuing education, professional courses and certifications can be valuable. But they should build upon a foundation, not replace one.

A short or weekend course cannot provide years of education in physiology, biochemistry, anatomy, nutrition and pathology, or the understanding required to see how these systems interact.

This becomes particularly important when someone is interpreting complex laboratory data and making recommendations that may affect your health.

You do not need to choose between conventional and private healthcare. Use each for what it does best.

Use conventional healthcare to investigate symptoms, rule out disease, access medically indicated standard testing, obtain diagnoses and receive appropriate medical treatment.

Use private healthcare when you want additional time, prevention, deeper interpretation or clinically relevant specialised investigation beyond what is routinely available.

Good private healthcare should not simply recreate your annual physical with better marketing.

It should add another layer.
