Our address 

We are located at 8307 Gault Lane, San Antonio, Texas 78209. Gault Lane is one exit East of the San Antonio Airport inside Loop 410. Gault Lane runs between the Nissan dealership and Valero gas station.


You need to bring a valid, non-expired photo ID when you attend your screening visit.  We accept a government issued identification card such as a driver's license, state issued ID card or passport.

Arrival time  

You should arrive at least 30 minutes prior to your appointment time to complete your paperwork.

What if I am late for my  appointment?  

Every effort will be made to see you upon arrival, however, you may be asked to reschedule your screening appointment.

Fasting time  

Most studies will need fasting blood work in order to complete your screening process.  If you choose not to fast for your appointment, it will be necessary for you to come back for an additional visit. Fasting times are listed in the individual study's listings.

Surgically sterile females  

If you have had a hysterectomy, oophorectomy or tubal ligation, documentation of these procedures are required for most studies.  You must bring these documents to your screening appointment.  If your records are not already on file with us, please request this information from your doctor so you will have records when you come in to screen.

What is meant by 'overnights' on the study listing?  

"Overnights" mean that you will admit or check-in to our clinic and stay here 24 hours a day for the number of days/nights that are stated for that specific study. You will not leave the clinic until your discharge date. It does NOT mean that you check-in at night and leave during the day for work, etc.


The ICON facility is a non-smoking facility. Studies requiring smokers will provide accommodations for smoking at the research clinic according to each study's schedule and requirements.
