Pre screening 

You may be asked at your initial appointment by the research team to consent to having your previous tumour biopsies used and additional blood samples taken at this appointment

 

These biopsies and blood samples will be used to see if your tumour matches the profile for any of the
trials running in the unit, results from these samples may take up to eight weeks

 

Even after the results are back this does not guarantee you a slot on a trial - Not all trials need pre screening

 

In the video below, Dr Alastair Greystoke explains more about what is involved during pre screening and why it is done within clinical research
