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 a 12-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.
