About Us

The original company was founded in 2005 by Nichola McChrystal, who pioneered the concept of DNA Clinics.

We became the first in the industry to offer ethical DNA Testing and provide face to face appointments through a network of DNA Clinics.

Crystal Health Group now specialises in delivering DNA, drug and alcohol testing services, including occupational health services, such as workplace medicals. In addition, our network of sample collection has grown to more than 100 locations throughout the UK. The head office is based in Manchester, where all tests and medicals are coordinated from, including the laboratory analysis and sample collection appointments.

About Crystal Health Group


Nichola is still very much involved in the development of Crystal Health Group. Also, she continues to provide expert advice and support to clients. For example, she provides evidence at employment tribunals, representing both employees and employers. Her knowledge and experience provided vital testimony in one particular case. As a result, this led to a successful outcome for the employee. Nichola has also arranged DNA Testing for long lost families. This was featured on a BBC documentary called ‘Family Finders’.

Her work in this area and continued business success have not gone unnoticed. This came in the form of an award in 2014 for ‘Women in Business Young Entrepreneur of the Year’. Nichola went on to dedicate the award to her Mum and Nan.

Crystal health group values

About Crystal Health Group


We believe that strong values define our business. This provides us with a robust plan to achieve our aims.

As a result, we have introduced a set of ‘Values and Behaviours’. These describe the professional behaviours we expect from our employees.

Our senior management team and employees developed this concept. As such, they form an integral part of the framework we use to recruit and retain our staff. We then continually develop our employees by assessing and rewarding their performance.
