This was an amazing collaboration between our lab, the National Institute for Communicable Diseases in Johannesburg, South Africa, and also Dr. Michael Jordan and Dr. Alice Tang at the Tufts School of Medicine.

Beyond the clear importance of supporting international efforts to end the AIDS epidemic by increasing access to viral load measurements, we are also excited about the potential for these cards to broadly support applications in decentralized clinical testing.

When treated as a ‘drop in’ replacement for the Roche PSC, without altering standard protocols, our dried plasma spot cards demonstrated improved accuracy of viral load band placement and also the reflexive identification of drug resistance mutations.
