Why participate?

If you decide to participate in a clinical study you will help strengthen research and contribute to medical progression such as improved patient safety and better treatment methods. In addition you often get a health check yourself. You may get the opportunity to try out a new diet, medication or a new method of treatment, and health professionals will closely monitor you.

It is important to be aware that joining a clinical trial expects a lot of you as a participant. The examinations can be extensive. Usually, several visits are needed which may last for hours each time. You have to remember to take medication/supplement, or go on a special diet. Often, blood drawning or insertion of a venous cannulation is needed, and sometimes urine and feces collection. 

How to participate?

In clinical trials there are both inclusion and exclusion criteria. If you wish to participate, you have to fulfill certain criteria. Each study has its own standard, however, general criteria are: age, gender, disease history, sample results and current drug use. 


It is important to emphasize that participation is clinical trials are voluntary. You should be aware that at any time during the course of the study, you are always allowed to withdraw, without having to give a reason. If you are were to take part in a clinical study, it is important that you recieve adequate and clear information. You will be provided with a detailed description of how the study will be conducted, along with what is expected from you as a participant.
