Experts Warn Against Social Media's Promotion of Unnecessary Medical Tests
A new campaign is targeting three controversial medical tests that are being heavily promoted on social media, aiming to combat widespread health misinformation online. The initiative, backed by research from the University of Sydney, focuses on full-body MRI scans, blood tests for testosterone levels, and the Anti-Mullerian hormone (AMH) or 'egg-timer' test.
Risks of Over-Diagnosis and Misinformation
Dr Brooke Nickel, a senior research fellow at the Sydney Health Literacy Lab, warns that these tests carry significant risks of over-diagnosis. This can lead healthy individuals to seek unnecessary interventions, driven by fearmongering from influencers who often omit critical information about potential harms.
Full-body MRI scans, marketed by celebrities like Kim Kardashian and Paris Hilton, are sold as tools for early disease detection, particularly cancer. However, medical bodies such as the Royal Australian and New Zealand College of Radiologists recommend against them for healthy people, citing no evidence of improved health outcomes. Instead, these scans can detect incidental findings, such as very early cancers that may never cause symptoms, leading to anxiety and unnecessary treatments like radiotherapy or surgery.
Psychological Harms of Fertility and Hormone Tests
The AMH test is often inaccurately marketed as a measure of women's fertility, preying on vulnerabilities and creating false timelines. While useful in IVF for women with infertility signs, it is unreliable for the general population. This can result in psychological distress, prompting costly and unwarranted procedures like elective egg-freezing or IVF.
Similarly, testosterone tests are promoted to men as a way to check for 'optimal' hormone levels, often linked to testosterone supplementation. This can lead to negative side effects, including blood clotting, impaired fertility, and potential heart conditions in healthy men who do not need it.
Access and Marketing Loopholes
Social media has created a 'wild, wild west' environment where companies bypass traditional medical oversight, marketing tests directly to consumers. Full-body MRIs are offered at wellness clinics, while AMH tests can be ordered online with results mailed back, leaving consumers to interpret complex data without professional guidance. Testosterone tests are often accessed through clinics or hidden-market avenues, exacerbating risks.
Campaign to Promote Evidence-Based Information
The campaign emphasizes that true disease prevention involves healthy lifestyle choices and consulting doctors when necessary, rather than relying on marketed tests. Over the next month, videos will be released on the university's social media platforms, partnering with medical colleges to provide evidence-based information and counteract the persuasive marketing that fuels a 'worried well' population.
