This category covers services that individuals use to understand their own health: blood tests and preventive checks ordered online, telehealth consultations, and consumer DNA tests reporting on ancestry or genetic predisposition. The customer is usually a private person, but employers and insurers also offer such services within wellbeing programmes, which raises the question of who sees the results.
The sovereignty question is what happens to samples and results afterwards. Genetic data cannot be changed or revoked, so an acquisition or insolvency can move it into another jurisdiction. The laboratory and sample storage may also sit in a different country from the app. The European Health Data Space regulation gives people rights over their electronic health data and limits secondary use to defined purposes, under a permit and in secure environments. That is a useful benchmark.
When choosing a European provider, ask where samples are analysed and how long they are kept, whether research use is a separate opt-in, and whether you can have both the data and the sample destroyed. Look for an identifiable physician or accredited laboratory behind the result, and for clear terms on what happens if the company is sold.
