Our Future Health, the UK's largest health research programme, will open appointments in 20 new locations next month, including in Runcorn.
There will be 210 clinics in total across the country.
The programme's mobile clinics will be situated in the car parks of Carlisle, Dover, Gainsborough, Kirkby, Middlesbrough, Milton Keynes, Newton Abbot, North Tyneside, Paignton, Redruth, Runcorn, Scunthorpe, and Tavistock.
New clinics will also be opened in Boots stores in Falkirk, Wimbledon, Northampton, Sunderland, Swansea, and Wrexham.
Following their recent partnership with Tesco, a new clinic will also open within the pharmacy at Tesco Cheshunt.
Our Future Health aims to transform the prevention, detection, and treatment of conditions such as dementia, cancer, diabetes, heart disease, asthma, and stroke.
With up to five million volunteers across the country, the programme aspires to create one of the most detailed pictures of people's health.
Volunteers are required to give a blood sample and have some physical measurements taken at the clinic.
They will also be provided with information about their health, including blood pressure and cholesterol levels.
In the future, volunteers will have the chance to receive feedback about their risk of certain diseases and participate in research studies.
Dr Raghib Ali, chief executive and medical officer of Our Future Health, said: "We’re thrilled to now be the world’s largest health research programme of its kind, thanks to over two million people who have signed up to volunteer and make a difference to the future of healthcare.
"We’re opening more clinics each month across England, Scotland, and Wales because we want everyone to have the opportunity to do something they may never have done before and represent their community in discoveries about diseases."
The programme is sending invitation letters to people living near the new clinics.
However, participation is not restricted to those who receive an invitation.
Anyone over the age of 18 can sign up online, complete an online health questionnaire, and book a short clinic appointment.
Our Future Health is being rolled out region by region to encourage adult participation across the UK.
Those not living near a location where appointments are currently available can still join and will be notified when new appointment locations become available.
Our Future Health is a collaboration between the public sector, life sciences companies, and leading UK health charities including Alzheimer's Society, Asthma and Lung UK, Blood Cancer UK, Brain Tumour Research, Breast Cancer Now, British Heart Foundation, Cancer Research UK, Diabetes UK, Glaucoma UK, Kidney Research UK, Pancreatic Cancer UK, Parkinson’s UK, Prostate Cancer Research, Prostate Cancer UK, Stroke Association, and Versus Arthritis.
It was set up with funding from the UKRI Accelerating Detection of Disease Challenge, delivered by Innovate UK.
