There are lots of different types of research for you to take part in. Each research study requires people who meet certain criteria to take part. For example, they may need people who take a particular medication or are a certain age.
These criteria are important because they make sure the study produces the best possible results. When we contact you about a study, we will tell you the criteria the researchers are looking for.
If you do not fit these criteria you would not be able to take part. Some studies have very detailed criteria and the researcher may need to obtain information or results from your medical records.
If this is the case, the researcher will always ask your permission to contact your GP or hospital team. The researcher will tell them about the study to make sure you are suitable to take part.
