Clinical Trial Participation Part 1: Eligibility

Posted by: My Kidney Research

Safety and scientific integrity should be the top priorities when conducting clinical trials. To maintain the highest level of safety for participants while also seeking the most valuable information possible, researchers set specific eligibility criteria when evaluating potential participants.

What are the eligibility requirements?

Different trials have their own specific criteria, depending on the questions the research is designed to answer. While each trial has its own specific needs, there are trials all over the country for just about anyone, including men and women of various ages, different fitness and health levels, and participants both with and without kidney, liver, and other organ complications.

First steps in checking eligibility

While each organization has its own specific system for evaluating eligibility, here’s what the process could look like at a typical research clinic:


1)   Website

Most research organizations will have a website listing current trials, and anyone can check to see what types of trial participants the organization is recruiting. Another site listing current trials is The trials can change frequently, so you may want to check the site often.


2)   Phone interviewDaVita Clinical Research

Through a phone interview, a recruiter will ask some general questions to find out which study might be the right fit for you. During this phase, the recruiter will provide general information about the possible trials you may be eligible for, as well as dates and other general details.


3)   Physical screening

The next step usually involves participants providing their complete medical history and undergoing a health screening by a licensed medical physician. Before agreeing to participate in the study each participant will sign an informed consent form (ICF) to ensure he or she fully understands all expectations. Research clinics respect your privacy and no information will be given out about your participation and/or your medical information unless required by law.


Again, this may be a good time to ask as many questions as you have. The National Institute of Health provides a list of questions you should ask while considering participating in a clinical trial.


4) Study confirmation

After the screening visit, participants will be notified if they qualify for the study and will be given the dates and times of the study as well as other related information.
