Convenience, Confidence and Support

This has been our Mantra since our founder Nichola Lawton, founded the original company back in 2005. Since then, we have grown and now provide a comprehensive suite of bio-testing services. Our presence in London has also grown. Consequently, we are one of the biggest providers of drug testing related services in the Greater London area. In fact, we now have 14 locations, providing drug and alcohol tests, DNA testing and Workplace Medicals. In short, this provides the convenience our clients demand.

The Confidence in our testing services comes from the ISO certification and Laboratory accreditation we achieve and maintain. Importantly, this sets up apart from other providers in London who do not achieve the required level of compliance. As a result, your personal information is processed and maintained in accordance with all GDPR requirements.

Finally, the support we provide is delivered through our highly educated and experienced team. Consequently, you will be speaking to ‘science degree educated’ Clinical Advisors. Our Advisors are on hand to guide you through the testing process and provide you with answers to any questions you may have.

My role at Crystal Health Group is to put in layman’s terms how each of our tests work. Importantly, its key that our clients understand how the test can give them the answers they need.
