- You will be asked to avoid strenuous exercise for 24 hours before the visit. Strenuous exercise may interfere with the results of some of the blood tests.
- You will be asked to fast from midnight before your visit to us (i.e. eat normally the night before and avoid any breakfast on the morning of the scan). You will be allowed to eat after blood sample collection.
If you are unable to fast or forget, you can still take part in this study and we will still collect blood samples, but it is important that you tell us that you have eaten so we can note it down.
