Before taking part in a clinical trial, you must qualify for the clinical trial.
Every clinical trial has specific guidelines that explain who can participate in the clinical trial. These guidelines are called inclusion and exclusion criteria.
These criteria may specify the age and sex of the patients who may participate, for example. They may also explain the types of disease and other medical conditions that you must or must not have to be eligible.
The inclusion and exclusion criteria help researchers identify appropriate patients for a clinical trial.
