TESTING & OUTREACH

The San Antonio AIDS Foundation provides more than 4,000 rapid HIV tests each year to residents in San Antonio and surrounding communities and counties.

 
AVAILABLE TESTING
  • HIV

  • Syphilis

  • Gonorrhea

  • Chlamydia

​​
 

All screening and confirmatory services are provided free of charge.
Counseling is available in English and Spanish.

​

HIV testing is performed using the INSTI HIV Antibody test. It requires a tiny amount of blood from a finger-stick and results are available in 60 seconds. 

Confirmatory HIV testing is provided if initial result is positive, with Rapid Start linkage to medical and social services and pharmaceutical assistance.

​

SAAF uses the Syphilis Health Check™ - Rapid Syphilis Tests with results available in 10 minutes. Gonorrhea and chlamydia results are available in 7-10 days through the DSHS lab.

​

There is a “window period,” this is the time between when you may have been exposed to HIV or an STI (Sexually Transmitted Infection) and when it can be detected by a test.

 

If you test during this window period, your result could come back negative even if you are exposed, this is called a false negative.

 

Your health and peace of mind are important to us.
Thank you for your understanding and cooperation!
