INSTI Multiplex HIV-1 / HIV-2 Syphilis Antibody Test

HIV and syphilis co-infection is a growing global health concern. The two infections share common transmission routes, and the presence of syphilis can increase both the risk of acquiring HIV and the likelihood of transmitting it. In populations where one infection is prevalent, the other is often close behind.

Traditional screening protocols require separate tests for each infection, doubling the time, supplies, and steps involved. The INSTI Multiplex changes that. One fingerstick, one test device, one minute. Both results appear on the same membrane unit, clearly differentiated by distinct dot positions.

For healthcare providers, this means faster throughput in high-volume settings, reduced supply costs, and fewer opportunities for patients to leave before receiving results. For public health programs, it means more comprehensive screening with less complexity.

Detects HIV-1 antibodies, HIV-2 antibodies, and antibodies directed against Treponema pallidum (syphilis) antigens from one sample. Eliminates the need for separate HIV and syphilis rapid tests. Reduces per-patient testing time and consumable costs. Supports prenatal screening, sexual health programs, and outreach settings where co-infection risk is elevated. Minimizes lost-to-follow-up by delivering both results before the patient leaves.
