Our mission is to improve the quality of life and
increase cancer patients' survival using
cutting-edge technological innovations to
identify the optimal treatment for each patient.

CanCertain utilises advanced 3D cell culture techniques to recommend personalised cancer treatments, improving patient quality of life and efficacy in eliminating cancer cells. With a turnaround time of just 8 working days*, the CanCertain personalised plan helps the patient begin the most effective cancer treatment quickly, thus increasing the chances of early recovery.

Despite the development of newer targeted therapies, most cancer patients receive a ‘one-size fits all’ treatment plan. This is because of a systematic constraint in cancer treatment selection – multiple (often sequential) biomarker testing protocols, time-delays, etc. Patients subsequently suffer significant anxiety due to the uncertainty of the effectiveness of their treatment.

CanCertain helps focus the current approach by testing standard chemotherapies, targeted therapies and immunotherapies, allowing the patient to receive the most effective treatment first time.

Our vision is for every cancer patients’ treatment to be guided by our specialised clinical test and personalised treatment plan. We are committed to providing accurate, reliable, and validated results to inform treatment decisions for people with cancer.

CanCertain is with you every step of
the way in your fight with cancer.

*8 working days turnaround time is subject to any unforeseen delays in receiving the biopsy sample.

Our History

CanCertain Ltd was established in the UK by like-minded clinicians passionate about advancing innovative 3D cell culture techniques to identify the most effective treatment for each cancer patient.

In 2021, Clyz Labs Ltd rebranded to CanCertain Ltd. Our mission remains the same and continues to drive our long-term commitment to deliver personalised cancer treatment plans to people throughout the world.

Clinical Studies

Interim results from clinical trials undertaken at three NHS hospitals show CanCertain tests can significantly improve treatment response rates in lung cancer patients (from 55% to 90%) – the clinical trial is ongoing and currently unpublished.
