Most health assessments tell you whether your numbers are in range. Mitochondrial testing asks a different question: how well are your cells actually producing energy?
It is a question standard bloodwork is not designed to answer. And it sits at the heart of how we age.
RCM Health offers private mitochondrial function testing as part of its specialized testing and diagnostics services – for clients who want to understand what is happening beneath the surface of their health.
What Mitochondria Actually Do
Every cell in your body contains between 500 and 1,000 mitochondria. These tiny structures convert the food you eat and the oxygen you breathe into ATP, the fuel that powers everything you do. Every heartbeat, every thought, every muscle contraction runs on ATP. Across your body, that adds up to roughly 37 trillion mitochondria working continuously to keep your energy flowing.
But mitochondria do more than make energy. They regulate cellular repair, inflammation, and metabolism. They sit at the intersection of nearly every major system in the body. That is why their decline is increasingly recognized as a root cause of chronic disease – not simply a consequence of it.
When Does Mitochondrial Dysfunction Occur
Mitochondrial dysfunction happens when the energy production system becomes inefficient, overwhelmed, or damaged. For the aging adult, the key question is how quickly mitochondria can recover from stress. When they cannot, the effects show up across the whole body.
Common signs include persistent fatigue that sleep does not resolve, brain fog, slow recovery after exercise, muscle weakness, and metabolic issues such as insulin resistance. Mitochondrial impairment has been linked to insulin resistance, cardiovascular disease, and Alzheimer’s disease. These are not coincidental associations. They reflect how central cellular energy is to every major organ system.
If your standard bloodwork has come back normal but you continue to feel unwell, mitochondrial function may be part of the picture. RCM Health’s health advocacy and consulting service helps clients navigate exactly this kind of gap between what standard testing shows and what they are actually experiencing.
A Conversation Worth Having With Your Physician
Several commonly prescribed medication classes carry documented effects on mitochondrial function. Statins can deplete coenzyme Q10, a molecule mitochondria depend on for energy production. Statin-associated muscle symptoms – including fatigue and weakness – affect an estimated 5 to 25 percent of patients in real-world settings, according to the National Lipid Association. Metformin affects a critical step in the cellular energy chain. Certain antidepressants, NSAIDs, anti-epileptics, and antibiotics have all been studied for mitochondrial impact.
This is not a reason to stop or question any medication. Those decisions belong with your prescribing physician. But if you are on long-term medication from these categories and experiencing unexplained fatigue or cognitive changes, mitochondrial function is worth raising with your healthcare provider – and it is something we assess as part of a comprehensive wellness review at RCM Health.
If you are managing a complex health picture and want an independent perspective before your next appointment, RCM Health’s medical second opinion service is available to review your full case.
How Does Mitochondrial Testing Work?
Standard bloodwork does not tell you how your cells are producing energy. A cholesterol panel tells you the car is running. Mitochondrial testing tells you whether the fuel is burning cleanly, whether the battery is charging, and whether the engine is degrading faster than it should.
Advanced mitochondrial testing – developed from science originally designed by NASA to monitor astronaut health – requires only a small blood sample. It assesses four core domains:
Aerobic energy production: How efficiently your mitochondria generate energy through the primary oxygen-dependent pathway.
Glycolytic backup capacity: Your body’s ability to produce energy when the primary pathway is under strain – relevant during illness, intense exercise, or periods of high demand.
Oxidative stress load: The level of cellular damage from free radicals, which accumulates when mitochondria are working inefficiently or under chronic pressure.
Cellular network function: How well your mitochondria communicate and coordinate across tissues – a marker of systemic resilience.
Together, these four measures reveal how efficiently your cells are working, and where there may be room to intervene. Mitochondrial testing is available through RCM Health’s testing and diagnostics services – no referral required.
What You Can Do
The encouraging news is that mitochondrial health is responsive. Targeted nutrition, exercise, stress management, and where appropriate, supplements such as CoQ10 can support mitochondrial function over time. Those conversations happen with your treating physician based on your individual results and history.
A test provides the baseline. A personalized plan turns that information into action.
Mitochondrial testing is part of how RCM Health helps clients understand what is happening beneath the surface of their health and build a plan around it. When appropriate, it can be paired with a medical second opinion and a broader review of your healthcare options.
Is mitochondrial testing covered by OHIP?
No. Mitochondrial function testing is not covered under the Ontario public health system and is not available through standard referral pathways. RCM Health offers it as a private, self-pay service. Contact us to discuss costs before booking.
Do I need a referral?
No referral is required. You can contact RCM Health directly to request an intake consultation through our testing and diagnostics services.
How is this different from standard bloodwork?
Standard blood panels measure markers like glucose, thyroid hormones, and blood cell counts. They do not measure how efficiently your cells are producing energy. Mitochondrial testing fills that gap with a functional assessment at the cellular level - which is why it often reveals issues that standard testing misses entirely.
Who is this testing for?
Mitochondrial function testing is most relevant for clients who experience persistent fatigue that doesn't resolve with rest, have normal standard bloodwork but continue to feel unwell, are managing a chronic condition and want to understand the cellular dimension, or are taking a proactive approach to long-term health and longevity.
Can I combine this with other RCM services?
Yes. Mitochondrial testing is frequently paired with medical second opinions, health advocacy support, or our broader testing and diagnostics services depending on your situation.
