What happens first?

If you want to be considered for a particular trial you would make an appointment to come to the Unit. If there is time we will send you some information about the trial before your appointment to read through. If not, you will be given the information as soon as you arrive and be given as much time as you need to read through the information. You will be asked to bring Identification (e.g. a passport) with you and your GP contact details.

Having read the information about the trial, one of the doctors will take you through the background and purpose of the study giving you a chance to ask any questions you like. We often do this in small groups and find this approach allows you to get the best understanding of what the trial is all about, however it is possible to request that you have some time alone with the doctor as well if you prefer.

Once you feel you have enough information to make the decision to take part the screening medical will commence. The screening visit will usually include having your heart traced (ECG), your blood pressure measured, blood samples taken (blood tests will include HIV and Hepatitis tests). You will have urine tests which will include a drug screen. During the screening a doctor will conduct a medical examination and you will be questioned by one of the doctors about your medical history and about any medication that you may have used.

After the screening visit we will contact your GP surgery to check that there is no history of a medical condition, which may affect your participation in the study. We will ask your GP to confirm any medication that you have used.
