The Problem Isn't Your Doctor
Your primary care physician is not failing you. We genuinely are trying our best. But many of us are operating inside a system that was never designed to find disease early. It was designed to manage disease once it arrives.
A standard annual physical is built around a checklist developed decades ago, optimized for billing codes and population-level guidelines, not for the individual biology of someone who wants to know where their specific risk actually lives.
The evidence on this is not ambiguous. A 2019 Cochrane systematic review pooled data from 17 randomized controlled trials involving more than 250,000 participants. The conclusion: general health checks had no measurable effect on total mortality, cardiovascular mortality, or cancer mortality.1 The evidence for total mortality was graded as high certainty. Health checks did increase the number of new diagnoses, primarily hypertension and high cholesterol, but that didn't translate into fewer heart attacks, fewer strokes, or longer lives.
The Society of General Internal Medicine, through the Choosing Wisely initiative, explicitly recommends against routine annual physicals in asymptomatic adults.2 The format is the problem. But it would be incomplete to blame the format alone. The reimbursement model is part of the architecture.
Most of the diagnostics discussed in this article are not covered by commercial insurance for asymptomatic screening. A coronary calcium score costs $75–150 out of pocket and takes ten minutes. It reclassifies cardiovascular risk in nearly half of intermediate-risk patients. Insurance rarely covers it for primary prevention. A DEXA scan that can quantify visceral fat is typically reimbursed only for osteoporosis screening in postmenopausal women, not for body composition. The incentive structure of coverage does not align with the goal of early, individualized detection. When the system won't pay for the test, the test doesn't get ordered. And the person walks out thinking they've been evaluated.
What Gets Missed
The annual physical doesn't measure most of the things that actually predict whether you'll have a cardiovascular event, develop cancer, or lose cognitive function in the next decade.
Your coronary arteries. A standard lipid panel tells you about particles floating in your blood. But it misses important particles like lipoprotein(a). It also tells you nothing about whether those particles have already built plaque in your arteries. Coronary CT angiography can directly visualize plaque, including soft plaque, the kind most likely to rupture and cause a heart attack. A coronary calcium score alone reclassifies cardiovascular risk in nearly half of patients considered "intermediate" risk by standard calculators.3 In the MESA cohort of 6,814 asymptomatic adults followed for over a decade, 44% of people eligible for statin therapy had a calcium score of zero.4 They were being treated for risk they may not actually have. Others with high scores were walking around with no idea.
Your cardiorespiratory fitness. VO₂ max, the maximum rate at which your body can use oxygen during exercise, is the single strongest predictor of all-cause mortality in the medical literature. An overview of 26 systematic reviews representing more than 20.9 million observations found that high fitness reduced the risk of all-cause death by 53% compared to low fitness.5 Each one-MET increase in cardiorespiratory fitness was associated with an 11–17% reduction in mortality.5 A 2018 JAMA Network Open study found no upper limit; extreme fitness carried the greatest survival benefit.6 Your annual physical does not measure this. It doesn't even estimate it.
Your body composition. BMI is a ratio of height and weight. It cannot distinguish between 200 pounds of muscle and 200 pounds of visceral fat. In a UK Biobank study of over 357,000 adults, higher visceral adiposity was associated with a 46% increase in cardiovascular mortality, independent of BMI.9 Where fat lives matters more than how much you weigh. DEXA scanning provides precise, regional measurement of fat mass, lean tissue, visceral adipose tissue, and bone mineral density. Two people with identical BMIs can have profoundly different metabolic risk profiles. The only way to see that difference is to actually measure it.
Your biological age. Epigenetic analysis, specifically DNA methylation testing, can estimate how quickly your cells are aging relative to your chronological age. It's a measurable, reproducible biomarker that reflects cumulative biological wear. No standard physical includes it.
Your brain. Neurocognitive decline begins decades before symptoms appear. Baseline cognitive testing using validated instruments, combined with blood-based neurodegeneration biomarkers, can establish where you stand today and track changes over time. No standard physical includes any of this either.
Your strength and mobility. This one is almost embarrassing in its simplicity. Grip strength, measured with a handheld dynamometer that costs less than a stethoscope, is one of the most powerful predictors of mortality in the medical literature. The PURE study, a prospective cohort of nearly 140,000 adults across 17 countries published in The Lancet, found that grip strength was a stronger predictor of all-cause and cardiovascular mortality than systolic blood pressure.11 A meta-analysis of 42 studies and over 3 million participants confirmed the finding: each 5 kg reduction in grip strength was associated with a 16% increase in all-cause mortality, a 17% increase in cardiovascular mortality, and a 9% increase in stroke risk.12 Stronger predictive value than the blood pressure cuff already on the wall. And yet grip strength is not measured in any standard annual physical. Not because the evidence is missing, but because a fifteen-minute visit built for billing codes has no room for it. The same is true of functional mobility assessments, gait speed, and balance testing, all of which predict falls, disability, and death in the literature, and none of which fit inside the current model.
A Note on the Limits of Screening
A common criticism of advanced screening is that detection without proven intervention is just expensive worry. But consider this: if a patient's cognitive testing shows early decline and their neurodegeneration biomarkers are trending in the wrong direction, they don't need a novel therapeutic. They need to walk. In a randomized controlled trial of 120 older adults, one year of moderate-intensity walking (40 minutes, three times per week) increased anterior hippocampal volume by 2%, effectively reversing one to two years of age-related brain atrophy. The control group's hippocampus continued to shrink.15 The screening didn't just generate data. It generated urgency. The intervention already existed. What was missing was the reason to start.
"You should exercise more" is the most ignored sentence in medicine. "Your brain is measurably shrinking and here is the one thing the evidence says can reverse it" is not.
But more testing is not automatically better testing. Advanced imaging carries real tradeoffs. Whole-body MRI in asymptomatic individuals flags critical or indeterminate findings in roughly one-third of people scanned, many of which prove to be false positives.7 Coronary CT angiography requires iodinated contrast and delivers 1–5 mSv of radiation on modern scanners.13 Mild contrast reactions occur in 1–3% of patients; severe anaphylaxis is rare but real.14 These are not reasons to avoid these tests. They are reasons to ensure that every study is ordered with shared decision-making, appropriate risk mitigation, and results interpreted by a physician who understands what warrants action and what doesn't. Screening without interpretation is not medicine. It's noise.
Where This Leaves Us
The annual physical answers one question: do you have a disease that is already causing problems? That's an important question. But it's the wrong question if your goal is to prevent the disease from arriving in the first place. Where is plaque forming, what is your true metabolic profile, how fast are your cells aging, is your brain where it should be: these require different tools, more time, and a fundamentally different model of care.
Medicine has already acknowledged that some of its oldest tools need to evolve. We moved from the stethoscope to bedside ultrasound, not because the stethoscope was useless, but because ultrasound showed us what we were missing. That shift happened because the evidence demanded it and the technology made it possible. The same logic applies here. The tools exist. The evidence is published in the same journals that inform every other aspect of modern medicine. The question is no longer whether these measurements matter. It's why they aren't standard.
That's the question we built Valincare to answer.
