The aim was to bring together different perspectives on this rapidly developing sector to identify the challenges and opportunities it raises for health services. Bringing together contributors from clinical practice, academia, journalism, industry, ethics, and regulation, the event featured presentations and discussions from:
- Professor John Powell: Professor of Digital Health, University of Oxford
- Deborah Cohen: Author, Journalist, Editor and Broadcaster; Senior Visiting Fellow, LSE
- Dr Helen O’Neill: Associate Professor in Reproductive and Molecular Genetics, UCL; CEO & Founder, Hertility Health
- Dr Sugha Murugesu: Obstetrics & Gynaecology Registrar / Medical Advisor, Hertility Health
- Mark Bartlett: CEO, StoreGene
- Dr Sharon Dixon: GP Partner and NIHR Doctoral Research Fellow
- Associate Professor Tim Child: Associate Professor of Reproductive Medicine, University of Oxford
- Associate Professor Dimitrios Koutoukidis: Associate Professor, University of Oxford
- Dr Rachel Horton: Research fellow at Centre for Human Genetics and clinical genetics ST6NHS Genomic Medicine Service
- Professor Anneke Lucassen: Professor of Genomic Medicine, Centre for Human Genetics and Director, Centre for Personalised Medicine
- Dr Alberto Giubilini: Senior Research Fellow, Uehiro Oxford Institute
- Professor Anthony Harnden: Chair, MHRA; Professor of Primary Care, University of Oxford
- Dr Joseph Burt: Head of Diagnostics and General Medical Devices, MHRA
Topics covered included digital health, clinical perspectives, fertility and hormone testing, genomics, nutrition, ethics, regulation, and social media, with speakers exploring how direct-to-consumer testing is reshaping healthcare experiences, patient pathways, health system boundaries, and wider public understandings of health. We will be sharing a full report on the day’s discussions in the coming months.
Among those attending was Grace Gould, a Year 12 student completing work experience with the Centre. Throughout the day, Grace helped support the event while also observing the talks and panel discussions firsthand. In the blog below, she reflects on the ideas, debates, and questions that stood out most to her. Her piece offers a thoughtful snapshot of how conversations about healthcare innovation can resonate with younger audiences and highlights the value of including emerging perspectives in discussions about the future of medicine and healthcare policy.
My Work Experience at the Direct-to-Consumer Medical Testing Conference
As part of my work experience with the Nuffield Department of Primary Care Health Sciences, shadowing Dr Francesca Dakin, I attended The Centre for Personalised Medicine’s (CPM) symposium – where Dr Dakin is a research fellow focused on direct-to-consumer (DTC) medical testing and personalised medicine.
Going into the day as a Year 12 student with more interest in healthcare policy and society than medicine itself, I expected to feel slightly out of my depth. However, despite the complexity of many discussions, the conference felt extremely welcoming and encouraged open debate between speakers and attendees.
I found myself genuinely fascinated by how broad the discussions became. They were not only scientific, but also ethical, sociological, technological, and political.
I started the morning helping set up the conference by organising name badges and welcoming attendees as they arrived. Throughout the day I was also asked to take notes and photographs for the conference review and my blog post, which encouraged me to engage much more closely with the talks and discussions. The event itself was extremely well organised, and during the breaks and lunch I had the opportunity to speak with professionals from a range of different backgrounds in healthcare, policy, and research.
Theme 1: Developments in Direct-to-Consumer Medical Testing:
The first theme explored how healthcare is rapidly changing through technology, AI, and digital innovation. The first speaker was John Powell, who discussed the “pace of change” within healthcare and how regulation often struggles to keep up with new technologies. One example which particularly stood out to me was the “Zapper”, a device from the 1990s which claimed to cure diseases such as cancer and HIV despite lacking scientific evidence. It highlighted how quickly medical products can spread without evidence when consumers are searching for reassurance or quick solutions.
Deborah Cohen, an author and journalist who wrote the book “Bad Influence” was the next speaker. Her talk focused heavily on the role social media now plays within healthcare and how platforms such as TikTok and Instagram increasingly blur the line between health advice and advertising. She discussed ideas such as “diagnostic odysseys”, where people spend years searching for explanations for symptoms after feeling unheard within healthcare settings. One point that really interested me was her discussion around algorithms and how social media can create a constant feedback loop where users are repeatedly shown health-related content, encouraging self-diagnosis and over-analysis of normal bodily functions. It definitely made me reflect on how easy it is for social media to influence the way people think about their own health.
Helen O’Neill’s discussion on fertility testing and women’s health was also interesting. She explored how many women turn towards DTC testing because of long waiting lists and gaps within women’s healthcare. I was surprised to learn how recently women were properly included in the research studies used to determine clinical testing and how limited historical research surrounding women’s health has been. Her company’s development of “GYN-AI”, an AI-supported diagnostic tool focused on women’s health conditions, demonstrated how technology might improve access to healthcare and reduce pressure on overstretched systems.
Panel Discussion Reflection:
In the panel discussion (chaired by Sally Sansom) that followed, Mark Bartlett, argued that if the NHS does not begin integrating more direct-to-consumer healthcare technologies and utilising the wider healthcare market, it may “fall behind” globally within healthcare innovation. But opinions were divided on this with some suggesting that a publicly funded health service like the NHS cannot operate a competitive market without widening health disparities further. Others wondered whether greater collaboration between private DTC companies and public healthcare services could reduce pressure on the NHS.

Theme 2: Implications of Direct-to-Consumer Medical Testing for Clinical Practice and Patient Pathways
The second theme focused on how DTC testing may begin to affect relationships between healthcare professionals and patients, particularly as at-home testing becomes increasingly common. Tim Child, who specialises in fertility discussed the rapid rise in at-home fertility and hormone testing, as well as the increasing number of people turning to online healthcare information in search of explanations for infertility. He argued that “more testing can create more suspicion than certainty.” He explained how many people become fixated on finding a specific explanation or “problem” that can be solved, even when test results may not actually change treatment outcomes. This linked closely to wider concerns surrounding over diagnosis and unnecessary anxiety, particularly when people begin repeatedly testing themselves without proper clinical guidance.
Tim also raised concerns about the reliability of some at-home tests, especially when testing is not carried out under proper clinical conditions. This made me think more critically about how many DTC tests are marketed as highly scientific and accurate, yet factors such as pre-test probability, timing, storage, and testing environments can significantly affect results.
Dimitrios Koutoukidis’ explored this theme further, with an interesting discussion surrounding DTC gut health and nutrition testing. He questioned how scientifically reliable some gut microbiome and food intolerance tests are, explaining that there is still no universally agreed definition of a “healthy” gut microbiome. This introduced another important debate running throughout the conference: just because technology allows us to measure something does not necessarily mean the results are clinically meaningful or useful.
Panel Discussion Reflection
The second panel discussion (chaired by Francesca Dakin) focused heavily on how DTC testing may begin to change the relationships between doctors and patients. Some panel members argued that AI, social media, and increased access to health information can encourage patients to become more informed and make consultations more conversational and collaborative.
However, others raised concerns surrounding situations where patients strongly trust DTC test results even when subsequent gold standard testing contradicts them. I found this discussion especially thought provoking because it highlighted how healthcare professionals may increasingly have to manage not only illnesses themselves, but also patients’ interpretations of online health information and private testing.

Theme 3: Ethical, Philosophical, and Regulatory Considerations of Direct-to-Consumer Medical Testing
The final theme focused on the ethical and regulatory challenges surrounding DTC healthcare. Many of the discussions became much more philosophical than I had expected. Joseph Burt, alongside Anthony Harnden, particularly explored the regulatory difficulties surrounding DTC healthcare and the challenge of balancing innovation with patient safety within increasingly commercialised digital healthcare spaces.
Anneke Lucassen linked genetics and personalised medicine. One idea I found interesting was the argument that genetic information does not exist in isolation. Genetics alone cannot fully predict health outcomes because environmental and social factors also play a huge role. This linked closely to wider concerns around inequality and access to healthcare, as people already better served by healthcare systems are often overrepresented in medical data.
The ethical discussions also explored the issue of commercialisation within DTC healthcare. Because companies are ultimately businesses, there can be tension between selling products and fully communicating the limitations of those products to consumers. This raised important questions about responsibility, regulation, and what ethical healthcare should look like in increasingly digital and commercialized spaces.
Panel Discussion Reflection
The final panel discussion (chaired by Anneke Lucassen) focused more on regulation and misinformation online, particularly surrounding influencers sharing incorrect medical advice across platforms such as TikTok and Instagram. One question raised was how regulators could realistically manage such a huge volume of online health content. Rather than arguing for complete censorship, several speakers instead emphasised the importance of education and encouraging accurate medical information online. I found this discussion especially relevant because social media has become such a major source of healthcare information for people in younger generations (like me), meaning influencers now hold significant power in shaping public understanding of health and medicine.

Before attending the conference, I mainly associated personalised medicine and DTC healthcare with things such as at-home DNA kits or fitness trackers. However, the day completely changed my perspective and opened my eyes to how broad the world of healthcare actually is beyond simply becoming a doctor or working directly within medicine. I found it really fascinating to see how healthcare is increasingly shaped not only by scientists and clinicians, but also by technology, AI, social media, business, ethics, and public policy.
What I found especially valuable was how many of the discussions extended far beyond science alone. I enjoyed seeing debates around regulation, misinformation, inequality, and the influence digital platforms now have on the way people understand their own health. It definitely made me think more critically about the relationship between healthcare, technology, and society, particularly as DTC testing continues to become more common.
Alongside the conference content itself, I also learnt a lot from observing how a professional conference is organised and run. The event felt extremely well structured and welcoming throughout the day, and it was interesting to see how discussions, panels, networking, and audience engagement were managed so smoothly. Overall, attending the conference was one of the most engaging parts of my work experience so far and gave me a much broader understanding of personalised medicine and the future challenges and opportunities surrounding healthcare innovation.
