The Biomarker Hierarchy: What to Test and When

You could test 100+ things today. Inflammation markers. Metabolic markers. Hormones. Minerals. Methylation. Lipoprotein particles. Glycation. Mitochondrial health. Gut permeability. Microbiome diversity. Toxin load. Epigenetics. Whole-body MRI. Multi-omics.

But here’s the thing: Until your data shapes your decisions, it’s just an expensive exercise of curiosity.

This is the problem with many health dashboards. They hand you a firehose of metrics without a funnel. You’re left staring at a sea of red flags and green ticks, wondering what matters most - and what the hell to do about it.

The Real Question Isn’t “What Can I Test?” It’s more along the lines of "Where am I in my health journey, and what level of insight do I need to move forward - not freeze in place?"

So let’s flip the question.

Not, “Which biomarkers are important?”
But, “What will I actually act on, given my current capacity, context, and clarity?”

This is the Biomarker Hierarchy. Not a strict pyramid, but a flexible lens for when to zoom in, and when to step back.

Level 1: Baseline Biomarkers – The Daily Drivers

Think of this as your dashboard warning lights. If you’ve never tested anything before, start here.

These are the foundationals:

  • Glucose & Insulin: Are you crashing by 4 PM or waking up groggy despite 8 hours of sleep? This duo tells you why.
  • Vitamin D, B12, Iron Panel: Mood swings? Fatigue? Hair loss? These three are low-hanging clues.
  • Liver & Kidney Function: How is your detox engine running behind the scenes?
  • CRP or ESR (Inflammation): Is there silent inflammation that’s been normalized as “just aging” or “just stress”?
  • Thyroid Panel: Feeling cold, constipated, or gaining weight despite a healthy routine? The thyroid often whispers before it screams.

Ideal for: Anyone starting their health journey, or doing a 6-monthly “tune-up.”
 

Actionable? Highly. These affect sleep, energy, mood, and metabolism directly.

Level 2: Advanced Panels - Precision, Not Panic

Let’s say you’ve already covered the basics, and something still feels off. Or you’re trying to get a clearer map of your future risks. That’s when you step into deeper terrain.

  • Lipoprotein(a), ApoB, Homocysteine: Going beyond cholesterol - what’s your true cardiovascular risk profile?
  • Cortisol & DHEA: Burnout, belly fat, poor recovery? This is your stress-resilience loop talking.
  • Ferritin + Transferrin Saturation + Serum Iron: Tired despite “normal” iron? These values fill in the story.
  • Sex Hormones (Estradiol, Progesterone, Testosterone, SHBG): Especially important if you're navigating PCOS, perimenopause, low libido, or unexplained weight changes.
  • Omega 3:6 Ratio & hs-CRP: What’s your body’s inflammatory balance like on a cellular level?

Ideal for: Those refining their plans, athletes, women navigating hormonal changes, or people who've hit a plateau.
 

Actionable? Yes - especially if paired with a coach, or if you’re tracking changes over time.

Level 3: Functional & Root-Cause Markers – The Why Behind the What

Now we move from symptom tracking to system mapping. These are less about “what’s broken” and more about “what’s misfiring under the hood.”

  • Organic Acids Test (OAT): Mitochondria, neurotransmitter precursors, nutrient co-factors - decoded.
  • GI Map or Comprehensive Stool Test: Are you absorbing what you eat? Is your gut creating inflammation?
  • Methylation Profile (MTHFR, etc): Your blueprint for detox, mood, and even how you handle caffeine.
  • Hair Mineral Analysis or Toxin Panels: Tired with no cause? It could be metals, mold, or minerals.

Ideal for: People with chronic symptoms, autoimmunity, “mystery” conditions, or those wanting to dig deeper into prevention.

Actionable? Can be - with interpretation. Don’t run these without guidance unless you love rabbit holes.

Level 4: Multi-Omics, Imaging & Biological Age – Your Personal Health OS

This is where testing becomes a strategy. You’re no longer chasing symptoms. You’re building systems.

  • Whole-Body MRI: Detects silent tumors, cysts, lesions, or anatomical red flags before they speak.
  • Epigenetic Biological Age / GrimAge / DunedinPACE: Are your habits aging you faster than your birth date?
  • Full-Omics Panels (Proteomics, Metabolomics): This is where research-grade tools meet longevity hacking.
  • Continuous Glucose Monitors (CGMs) + Wearables: Combine inner data with lived rhythms - this is your biofeedback loop in action.

Ideal for: Founders, athletes, longevity explorers, or anyone optimising for performance, prevention, or healthspan.
 

Actionable? Hugely - if you're ready to integrate it into a bigger life system.

So… What Will You Actually Act On?

You don’t need every test. You need the right test - at the right time - for the right reason. Here’s a quick way to decide:

How We Help You Cut Through the Noise

If you’ve ever felt overwhelmed by health tests, you’re not alone. It’s not about doing all the tests - it’s about doing the right one for where you are right now.

You might just need to get a better handle on your energy and mood before your next big work sprint. Or maybe you’re already thinking long game - how to avoid your parents’ health trajectory, or get ahead of silent risks.

Wherever you are, the question stays the same: Will this test change what I do tomorrow?

At Resolute, we make it about taking it steps further from just testing, into actually doing. We help you make sense of your biology - one decision, one habit, one recommendation at a time. No overwhelm. Just a clear, personalised path that meets you where you are.
