What Our Customers Are Saying

DeWayne Ford
Director of HIV Education and Prevention Service

This year we were able to test 72 people in a single day. As the event promotes HIV/AIDS awareness, it’s natural that we would also offer rapid HIV testing. We want to make sure everyone knows they can get their test results in 60 seconds. It’s so much easier and more attractive for people to come and get tested if they know it’s that fast.

AID Atlanta

When testing is fast and portable, it’s so much easier to offer it there and then. Removing the barriers to access is a huge priority for us. The INSTI test kit is game-changing because it allows people to know their status so quickly.

The HIMM Project

With the last test we were using, there were some concerns about window periods and the length of time it took for the test to run. It made outreach testing too complicated. Very quickly after trying INSTI in the field, we realized that a one-minute test would be ideal for use in public spaces and it could enhance our outreach programs
