The Risks of Influencer-Driven Health Tests: A Critical Examination

Social media influencers are increasingly promoting medical tests as tools for individuals to take control of their health. However, experts caution that these promotions often overlook significant risks associated with certain tests. A campaign led by the University of Sydney aims to address misinformation surrounding three controversial tests: full-body magnetic resonance imaging (MRI) scans, testosterone level blood tests, and the Anti-Mullerian hormone (AMH) test, which assesses a woman's egg count.

Full-body MRI scans have gained popularity through endorsements from celebrities like Kim Kardashian and Paris Hilton, who advocate for their use in early disease detection. Despite this, leading medical organizations, including the Royal Australian and New Zealand College of Radiologists, advise against these scans for healthy individuals. Dr. Brooke Nickel, a senior research fellow at the Sydney Health Literacy Lab, highlights that these scans can lead to over-diagnosis, where incidental findings may cause unnecessary anxiety and treatments, including invasive procedures.

The AMH test is marketed as a fertility indicator but is not a reliable measure for healthy women. Dr. Nickel points out that while the test can assist in IVF treatments for women with infertility signs, it can create psychological distress for those who receive misleading results about their reproductive timelines. This misinformation can lead to unnecessary interventions, such as elective egg-freezing or IVF, based on a false sense of urgency regarding fertility.

Testosterone tests are often marketed to men as a means to assess hormone levels. However, Dr. Nickel warns that these tests can promote testosterone supplementation, which carries risks such as blood clotting and impaired fertility. The marketing of these tests bypasses traditional medical oversight, placing the burden on consumers to interpret their results without professional guidance. This has resulted in instances where individuals, particularly young women, misinterpret their health status based on test outcomes.

The pervasive marketing of health tests creates a phenomenon known as the "worried well," where individuals feel compelled to seek tests and interventions that may not be necessary. Dr. Nickel emphasizes that genuine health prevention relies on fundamental lifestyle choices, such as proper nutrition, exercise, and regular consultations with healthcare professionals, rather than on the pursuit of potentially misleading tests.

In response to these concerns, the University of Sydney's campaign will release educational videos on platforms like Facebook, Instagram, and YouTube, partnering with medical colleges to disseminate evidence-based information about these health tests. This initiative aims to empower consumers with accurate knowledge and mitigate the risks associated with influencer-driven health marketing.

While the campaign seeks to address misinformation, there is a lack of comprehensive data on the long-term psychological effects of these tests on consumers. Additionally, the effectiveness of the campaign in changing public perception and behavior remains to be seen.

• “It can be pretty detrimental to be told you may not have enough eggs left and you need to speed up your reproductive timeline, or otherwise that they’re fine when in reality there might be other underlying issues.” — Dr. Brooke Nickel

• “But when the marketing is so persuasive and pervasive that it feels like the onus is on us as an individual to have to go and get these tests and be on top of our own health, it is really creating a population of the worried well.” — Dr. Brooke Nickel
