VO2 Max (Cardiopulmonary Exercise Testing)
Last reviewed 25 August 2026 · Evidence-graded review — see Methodology
A mask, a bike or treadmill, and a graded test to exhaustion measuring how much oxygen you can actually use. Longevity clinics have adopted it enthusiastically and for once the enthusiasm has a defensible basis: cardiorespiratory fitness is among the strongest measured predictors of all-cause mortality that exists. What it lacks is evidence that measuring it, rather than simply training, changes anything.
Mandsager K, Harb S, et al. “Association of Cardiorespiratory Fitness With Long-term Mortality Among Adults Undergoing Exercise Treadmill Testing.” JAMA Netw Open 2018;1:e183605 followed 122,007 patients and found a graded, inverse association between fitness and mortality with no observed ceiling of benefit — the gap between the least and most fit groups was larger than that associated with smoking, diabetes or coronary artery disease. The association is exceptionally strong. The grade stops at Moderate because no trial has shown that knowing your number improves outcomes over being told to exercise.

Singapore guidance
Not covered in the current review
Singapore’s national screening committee has not reviewed this test in the current volume of its report, which covers nine conditions. That is not a verdict either way.

What you would actually pay
- Healthier SG
- Not subsidised
- MediSave
- Not among the screenings named for outpatient claims
Source: Healthier SG Screening (HealthHub) and MediSave outpatient care (Ministry of Health). Absence from either list is not a statement that the test is discouraged — only that no subsidy or claim applies. Gross prices compared.
What it costs when it is wrong
- Basis
- No published harm criterion found
- Severity
- Not documented
Not covered in the current volume of the committee’s report, so no harm criterion was found either way.
An empty finding, not a clean bill of health: this means nothing documented was found for this test. It is not a claim that the test is safe.
Screening harm is not only a laboratory question: the committee’s own criteria advise against a test when “the screening test, or follow-up tests arising from a positive screen, are associated with significant medical risks”. Sources on overdiagnosis → · How this is graded.
FAQ
Is the VO2 Max (Cardiopulmonary Exercise Testing) worth doing in Singapore?
For adults without symptoms, VO2 Max (Cardiopulmonary Exercise Testing) sits at the moderate grade on our evidence scale. It typically costs S$250–600 in Singapore. The usual schedule: every 6–12 months if using it to track a training programme. Most appropriate for anyone using it as a training benchmark, and as an informative midlife baseline. Not a diagnostic test.
