Clinical trials enroll people with certain health problems as well as healthy volunteers, depending upon the type of trial a clinical research company is conducting. Often researchers decide who qualifies to participate in a clinical trial based on their age, gender, and health condition.
If you are interested to join a clinical trial, you need to first find out whether you are a suitable participant or not. You also need to talk to the researchers about the possible benefits and risks to your health from a clinical trial.
After analyzing all important aspects, the research team will determine whether or not you qualify for a clinical trial.
