9 out of 10 Brits changed lifestyle after clinically-guided at-home blood tests, study finds

In a new survey of nearly 500 UK adults, 9 in 10 people changed their lifestyle and habits after taking an at-home blood test and receiving personalised clinical guidance.

The survey, developed by UK health company Thriva, analysed 498 responses from its current users and focused on motivation and behaviours related to blood tests, health and lifestyle.

Although people are living longer, they now live an average of 20 years in poor health.

Addressing this gap, known as a person’s healthspan, is important for maintaining a good quality of life, well into old age.

The results show that after seeing their individual results, including vitamin, cholesterol or hormone levels, 90 per cent made at least one lifestyle change, 57 per cent started new vitamins or supplements and 56 per cent made dietary changes such as eating more fruit and vegetables or cutting sugar.

Recent scientific evidence questioning the reliability of rapid home health tests highlights the critical difference between unregulated point-of-care kits and clinically validated testing processed in accredited laboratories with full medical oversight.

Dr Vishal Shah, Chief Medical Officer at Thriva, says: “We don’t focus on rapid, one-off diagnostic tests.

“We support people to track key health metrics over time – such as HbA1c, LDL cholesterol and vitamin D – so they can spot trends early, make proactive changes, and monitor the impact.

“We back this up with robust clinical support – every result comes with a personalised GP report, tailored recommendations focused on sustainable lifestyle change, and the option to speak with a doctor.

“Our capillary blood samples are analysed in UKAS-accredited laboratories operating to ISO 15189:2022 standards – the same benchmark used across the NHS.

“Every part of our process is validated by our diagnostics partner Inuvi, including postal stability, biomarker comparability with venous blood, and overall clinical reliability.

“We welcome stronger regulation across the sector to ensure that all at-home testing meets the highest clinical standards.”

Lucas Denton, GP and Clinical Governance Lead at Thriva, added: “These findings suggest that people aren’t just looking to understand their health; they’re ready to make positive lifestyle changes when supported with the right tools and appropriate medical information.

“At a time when chronic illnesses like type 2 diabetes, cardiovascular disease and some cancers are on the rise, this shift in mindset and behaviour is an encouraging sign.

“I hope we continue to see more people across the UK feeling empowered to take proactive steps towards better long-term health.”
