About Us

Crystal Health Group's drug testing and occupational health services are delivered through a network of drug testing clinics, sample collection technicians and medical centres. Our brand includes DNA Clinics, delivered in partnership with Boots, demonstrating our reputation in delivering quality testing and occupational medical assessments since 2005.

Drug Testing Clinics

Our aims


With more than 100 locations throughout the UK, we aim to provide the convenience of a nearby sample collection service to all our clients. This includes private clients who wish to attend a clinic to have their samples collected for a drug and alcohol test. Or, our growing number of commercial clients who want the convenience of on-site workplace drug testing or medical assessment services. We will continue to assess and train our sample collection network, ensuring we continue to provide excellent coverage across the UK.

Our aims

Corporate Social Responsibility

As an independent family business, we aim to support our local community where we can. This ranges from supporting a local charity, or raising money for a special cause. In addition, we invested in apprenticeships back in 2017. This has paid dividends to the growth of our business and the development of local young people. So much so that we have two apprentices who are now in key positions within the business as operations and clinical account managers.
