Function Health’s Rapid growth Outpaces Publication of Key Research
Function Health, a direct-to-consumer health testing company, has amassed a significant customer base-reportedly numbering in the hundreds of thousands-by offering granular blood analysis and personalized recommendations. Though, the company has yet to publish peer-reviewed evidence supporting the clinical validity of many of its tests and resulting advice, raising questions about the scientific basis for its popular offerings.
Despite limited publicly available data, Function Health has successfully convinced a large number of consumers of the value in closely tracking biomarkers and following the company’s guidance. This success comes as the market for at-home health testing continues to expand,and as concerns grow regarding the potential for misleading or unproven health advice delivered directly to consumers. The lack of published research leaves open questions about whether Function Health’s tests and recommendations genuinely improve health outcomes, or if they primarily serve to generate revenue through unnecessary testing and interventions.
The company offers tests for conditions like cancer and coronary artery calcium, screenings not typically recommended for individuals at low risk of developing thes diseases. While Function Health states its tests are intended to be used in consultation with a physician, critics worry that the detailed data provided could lead to anxiety, unnecessary follow-up procedures, and potentially harmful self-treatment.
Function Health has not responded to requests for comment regarding its research pipeline or timeline for publication. The company’s website states it is “committed to scientific rigor” and “continuously evaluating and refining” its offerings, but details regarding specific studies and findings remain scarce. The absence of clear, peer-reviewed data raises concerns about accountability and the potential for conflicts of interest in a rapidly growing, multi-billion dollar industry.
