Who can participate in a clinical study?

Every year, thousands of clinical studies look for volunteers all over the world. Who these studies are looking for depends on the particular study. Some are looking for healthy participants, while others search for participants with a specific condition.

Every single person who participates in a clinical study is important, because without volunteers, there wouldn’t be any development of new treatments and medications.

Clinical studies have specific rules about who can participate. These rules are called eligibility criteria.

What are eligibility criteria?

In every study, there are criteria all participants must fulfil to be eligible for the study. The exact criteria differ from study to study, and are carefully developed to make sure that every participant will be safe in the study. Criteria are also important for ensuring that the results of the study will be correct.

The criteria for participating in a study can be based on things such as:

  • Age
  • Gender
  • Type and stage of a disease
  • History of treatment
  • Other medical conditions

There are two main types of criteria in clinical studies: inclusion criteria and exclusion criteria.

Inclusion Criteria

The inclusion criteria are the factors that determine if you can participate in a study.

Exclusion Criteria

The exclusion criteria are the factors that determine if you shouldn’t participate in a study. It’s important to remember that being excluded from participating in a study. They are not personal, but there to make sure that every participant will stay safe during the study.

Should I participate?

Participating in a clinical study is voluntary. Some of the reasons for considering joining a clinical study could be:

  • Getting access to the latest treatments specialized for your condition at no cost
  • Help advancing medical research and knowledge about diseases
  • Supporting the development of the treatments that can improve the lives of people in the future
