CLL Tracker has been developed to provide patients with Chronic Lymphocytic Leukaemia (CLL) with information provided by other patients who share the same condition. The data contained is actual patient specific information relating to blood results, prognostic markers, their personal experience of the different treatments and the resulting effects of these treatments.

Your Information

As we require information that is specific to you as an individual, we will only ask for that which is necessary for the function of the system, your name (or alias) and a valid email address.

Your Security

We will not under any circumstances publish your specific data or share this with any other party. We want the CLL patients that use this resource to feel fully protected.

This is an international website which is privately funded by a patient with CLL for the benefit of patients with CLL and has no commercial associations with any other organisations (medical or non-medical).
