The patients most likely to ask about VO2 max and DXA Scans are also your most valuable ones. If they’re not asking you, they’re finding the answer somewhere else…or possibly not finding it at all.
The gap isn’t clinical capability. Most concierge and functional medicine physicians already understand longevity medicine. The problem is infrastructure: how do you deliver high-end, measurable performance testing without adding staff, equipment, and operational overhead to a practice you’ve already carefully built? Most practices don’t have a good answer to that question. So the demand goes unmet, and the patients who most want objective data end up outside your care.
The longevity-motivated patient has changed. They’re not waiting for symptoms. They’re tracking sleep, monitoring HRV, and reading studies on VO2 max as a mortality predictor. They may even know what a DXA Scan is and roughly what it costs. What they’re looking for is a clinician who can put that data in context and build something actionable around it.
That patient is already in your practice. The question is whether you’re the one helping them or whether they’re piecing it together on their own: booking a scan at a boutique lab across town, interpreting results without clinical guidance, and quietly wondering why their physician isn’t more engaged with this side of their health.
A VO2 max score is not a number; it’s a window into how efficiently the cardiovascular system delivers oxygen to working muscle. Research consistently ranks it among the strongest independent predictors of all-cause mortality, stronger than many traditional clinical risk factors.
A DXA Scan does the same for body composition. It’s not a weight check. It’s a precise measurement of lean mass, fat mass, and bone density at a body-region level, which changes how you counsel patients on everything from protein targets to resistance training to medication considerations as they age.
Resting metabolic rate testing closes the loop: how much energy is this patient actually burning at rest, and is their nutrition strategy matched to that reality?
These tests aren’t exotic services. They’re the foundation of any serious longevity protocol. The patients who want them are already in your waiting room. And right now, most of them aren’t getting access to these services from you.
Most practices don’t offer these services because of what it would take to stand them up. You’d need equipment, a trained physiologist on staff to administer and interpret testing, scheduling infrastructure, and a workflow for integrating results into your existing care model. For a practice running at capacity, that’s not a small lift.
And in reality, the goal isn’t to become a performance lab. The goal is to offer your patients access to one, with your practice at the center of their care.
That looks like this: you refer a patient for a VO2 max assessment and DXA Scan. They’re tested and interpreted by a master’s-level physiologist, and you receive a structured clinical summary that integrates directly into your care plan. The patient gets objective data. You get a richer clinical picture and a reason for a meaningful follow-up conversation.
No new staff, no new equipment, no new overhead; just a seamless integration between your clinical judgement and the lab’s performance data, so everything focused on how you care for that patient.
The lab becomes an extension of your practice rather than a competitor to it.
Concierge medicine is growing. The patients choosing it are doing so because they want more from their physician relationship, and that expectation keeps rising. Comprehensive longevity services are quickly becoming a baseline expectation among health-engaged, high-value patients, not a premium add-on.
Practices that can offer these services, or credibly connect their patients to them, have a differentiation advantage that’s difficult to replicate. Those that can’t are increasingly at risk of losing their most proactive patients to practices that do.
The market for this is not niche. The longevity-motivated patient is the same patient choosing concierge medicine in the first place. You already have them. The only open question is how much of their health journey you’re part of.
Clinicians who have added objective performance testing through a partnership with Human Powered Health consistently describe two benefits: better patient conversations and higher patient retention.
Better conversations because you’re no longer working from subjective reporting alone. You have a VO2 max number, a lean mass measurement, a basal metabolic rate. You can set specific performance targets and track progress against them over time. Visits become a performance review, not a checkbox.
Higher retention because patients who are improving their numbers come back. They’re invested. They have a goal. And you’re the clinician who gave them a way to measure it.
The debrief is where it lands: the 20-minute conversation where a patient sees their VO2 max percentile for the first time, understands what it means for the next decade, and asks what they should do about it. That exchange belongs in your practice, not at a lab they found on their own.
Your most motivated patients are already searching for this. Some rely on inaccurate data from smart watches or scales. Some aren’t finding it at all and are settling for incomplete information. A small number have found their way to a clinician who offers it, and they’re not leaving.
The infrastructure to deliver these services without building a lab doesn’t have to be yours. The relationship with the patient, and the clinical picture that objective data creates, can be.
That’s the gap. And it’s one worth closing.
