What your annual physical actually misses — and why it matters

You go every year. You get your blood drawn. Your doctor says everything looks fine. You leave feeling vaguely reassured. And in many cases, the most important things about your health were never measured.

This isn't about blaming your physician — they're working within a system designed for 15-minute visits and standardized panels. It's about understanding what a standard annual physical actually checks, what it doesn't, and where the blind spots are.

What's typically included

A standard annual physical in the US usually includes: blood pressure, weight, a basic physical exam, and a "standard" blood panel. That panel typically contains: total cholesterol, LDL-C (calculated, not measured), HDL-C, triglycerides, fasting glucose, basic metabolic panel (sodium, potassium, creatinine, BUN), CBC, and sometimes TSH and liver enzymes.

This is fine as far as it goes. The problem is how far it doesn't go.

The six most important gaps

1. ApoB and Lipoprotein(a) — missing from the lipid panel

Standard panels report LDL-C — a calculated estimate of cholesterol content. They don't measure ApoB (the actual count of atherogenic particles, ESC Class I recommendation) or Lipoprotein(a) (a genetically determined risk factor affecting 20% of people). Two people with identical LDL-C can have wildly different actual cardiovascular risk. ApoB and Lp(a) catch what LDL-C misses.

2. Fasting insulin / HOMA-IR — missing from metabolic screening

Standard panels check fasting glucose and sometimes HbA1c. Neither can detect insulin resistance in its early stages — 5 to 15 years before glucose becomes abnormal. Fasting insulin, calculated as HOMA-IR, is the early warning system. It costs about €15. It's almost never ordered.

3. VO₂max — fitness is never measured

Cardiorespiratory fitness is the single strongest predictor of all-cause mortality — stronger than blood pressure, cholesterol, or smoking status. No standard annual physical includes a measurement of fitness. Not an estimate, not a questionnaire — an actual measurement. At Health Detectors, we measure VO₂max via spiroergometry on Day 1.

4. Body composition — BMI is not enough

BMI tells you nothing about the distribution of fat vs. muscle, and nothing about visceral fat — the metabolically dangerous fat around your organs. A muscular person and an obese person with the same BMI have completely different risk profiles. Body composition analysis (BIA or DEXA) provides this information. BMI alone does not.

5. Comprehensive liver assessment — ALT alone isn't enough

Standard panels include ALT, maybe AST and GGT. But the "normal" ranges used by most labs are too high — they were established before the NAFLD epidemic. Using evidence-based thresholds (<25 for men, <19 for women), many patients with fatty liver are missed. A complete assessment adds ALP, LDH, total protein/albumin, and — when indicated — ultrasound.

6. Vitamin D, B12, Ferritin, Magnesium — micronutrients

Deficiency rates for these nutrients are substantial: 40%+ for vitamin D in Europe, 10–30% for magnesium, significant B12 deficiency in vegans and older adults. Standard panels don't include any of them. Deficiencies are cheap to detect and cheap to treat — but you have to look.
