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 common tests sold in wellness panels can also be ordered by your clinician when medically appropriate. Whether your plan covers them, and what you owe, depends on your benefits, network and deductible.

Before ordering a test yourself, ask whether your clinician recommends it, whether your plan covers it, and what you would pay.

If a test is not medically indicated or is not covered, ask what the result would change before deciding to pay for it yourself.

Check your benefits and likely costs before paying for a separate test.

A self-pay health assessment is not advanced simply because it includes blood tests.

Basic blood tests can help diagnose or monitor medical conditions. Packaging them in a wellness panel or a polished dashboard does not make the tests more informative.

Additional care earns its price when it answers a useful question.

• More time to understand a complex health history
• A preventive assessment tailored to your history and risk factors
• A careful review of existing results in context
• Connecting patterns across symptoms, history and laboratory data
• Specialized tests with a clear reason for ordering them
• Translating findings into a practical strategy

Depending on your history and the clinical question, additional testing might examine nutrient status, specific exposures, inherited risk or metabolic health. Ask about the evidence, limitations and next steps before ordering it.

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. Is the test appropriate for me, and can my clinician order it through my health plan?
• 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

For a diagnosis, prescription or medical treatment, see a licensed clinician qualified to provide that service in your state.

Nutrition advice

For individualized nutrition advice, look at education, clinical training and credentials. A Registered Dietitian Nutritionist (RDN) has a defined professional credential; other nutrition titles and licensing requirements vary by state.

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 specialized testing or calls their approach functional or integrative medicine, ask about their relevant training, professional license where applicable, and scope of practice.

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 specialized 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 on toxicology, genetics, advanced nutrition or specialized laboratory assessment, look for meaningful education and experience 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.

Your regular medical care and additional services can work together. Be clear about what each is meant to do.

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

Consider additional care when you want more time, a focused preventive assessment or interpretation that helps you make a decision. Check coverage and cost first.

A paid assessment should give you more than a repackaged annual physical.

It should help you make a better decision.
