It is important to understand that even if you feel that you meet all the above criteria, you are still required to complete the protocol screening procedures.  Scheduling a screening appointment does not guarantee that you will qualify for that study. Additionally, subjects are screened on a first come-first served basis and studies may complete enrollment prior to your visit.  

No guarantees can be made regarding group assignments for any particular study.  ICON will not assume any liability for lost time, travel or failure to qualify.

To determine if you fully qualify, it will be necessary to obtain blood and urine  samples after an 8-hour fast.  You have the option of fasting for a blood or urine sample at the screening appointment, or, you may return at a later date for us to obtain these samples. 

If you fast, you should refrain from eating or drinking anything (with the exception of water) for 8 hours before your appointment.  We will be testing for tobacco use and drug abuse.  Please refrain from consuming alcohol at least 24 hours prior to your screening appointment. 

Be sure to bring all of your medications with you to your screening appointment. 

Please note, you need to bring a valid, non-expired photo ID with you when you attend your screening visit.  We accept a government issued identification card such as a driver's license, state issued ID card, military ID or passport.  You will be required to show this same photo ID at all study visits.

You will be filling out paperwork for the study.  Please arrive at least 30 minutes in advance of your screening appointment.  If you are late for your appointment you may not be seen or may need to reschedule.
