What to Expect

What to Expect from a Paid Clinical Trial

Should You Participate in Paid Clinical Trials?

For those who have never participated in a clinical trial, we understand that it can feel somewhat intimidating, and may make you wonder if you should participate at all. Clinical trial participation is essential to the development of new, life-changing treatments and medicines. We need volunteers like you to help us in our mission to advance global health. That being said, it’s our duty to ensure that you are as informed as possible about what to expect when participating in paid clinical trials at WCCT Global.

Our relationship with our volunteers begins long before we meet at one of WCCT’s Southern California facilities. We regularly attend community events and advertise to help raise awareness for clinical research and the need to identify willing trial volunteers. Once you have shown interest, either by reaching out to us or signing up to learn more, one of our friendly volunteer recruiters will reach out to you to collect some basic background and medical information to determine if you potentially qualify for any of the clinical studies being conducted.

Screening Visits

If you qualify for one of our paid clinical trials based on your initial conversation with our recruiters, you’ll be invited to come in for a screening visit. There, with your permission, we’ll conduct a few tests to see if you qualify for the study you signed up for, based on that study’s specific requirements.

Examples of tests that may be performed are:

  • Vitals (blood pressure, heart rate, respiratory rate, temperature)
  • Height and weight
  • Blood draw
  • Urine sampling
  • ECG (check for any abnormalities with your heart)
  • Physical performed by a doctor

You will receive your test results within three to five business days, and we’ll let you know if you’ve qualified for the study. If so, you’ll be invited back to our facility to take part in a follow-up visit or overnight stay.

Overnight Stays

Some paid clinical trials involve overnight stays. If the study you are participating in involves an overnight stay at our facility, you will be checked in at a previously determined date along with other study volunteers like yourself. You’ll have a room to stay in throughout your visit. Each day, you’ll be administered the investigational medication, and your readings will be regularly monitored to observe your body’s reaction. You’ll be tested again after each dosing to determine how the medication is influencing your readings, and to make sure, above all, that you are safe and in good health. You will meet with a doctor periodically throughout the study to verify your good health, and to determine if you are experiencing any side effects from the medication.

During your stay, you will be provided with three meals and snacks every day, and you will have access to amenities to help you pass the time (Netflix, video games, internet and computer access, etc.). For longer stays, you’ll even have the opportunity to visit with friends and family. Once your stay is complete, you’ll be checked out and called back for any follow-up visits that may be required in the study’s protocol. These visits can range anywhere from a few days to a few weeks after you have completed your stay.

Follow-Up Visits

Follow-up visits are much like overnight stays, in that you will be administered a medication and tests will be re-performed to see how your body is reacting, but you don’t have to stay overnight. Follow-up visits are usually short check-ups conducted at our facility for continued evaluation of the medication. Some follow-ups don’t even require you to come into the facility. All you’ll need to do is check in periodically over the phone.


We know that helping WCCT in its mission to advance global health is rewarding enough for our volunteers, but there are additional benefits to participating in clinical research. On top of the free study-related care that you’ll receive throughout your participation, such as blood tests, physicals and vital sign readings, participants may be compensated for their time and travel. It is our way of saying thank you for helping WCCT!
