Chembio Announces the Receipt of CLIA Waiver for its DPP HIV-Syphilis System

MEDFORD, N.Y., Feb. 24, 2023 (GLOBE NEWSWIRE) — Chembio Diagnostics, Inc. (Nasdaq: CEMI), a leading point-of-care diagnostics company focused on infectious diseases, today announced receipt of a Clinical Laboratory Improvement Amendments (CLIA) waiver from the U.S. Food and Drug Administration (FDA) for the DPP HIV-Syphilis System.

“The DPP HIV-Syphilis System represents an exciting advancement in rapid testing for sexually transmitted infections. We are excited that the 200,000+ CLIA waived point-of-care testing sites in the U.S. now have access to the DPP HIV-Syphilis System where its use can help save lives and minimize the spread of both HIV and syphilis,” said Richard L. Eberly, Chembio’s President and Chief Executive Officer. “Rapid HIV and syphilis combination testing is now even more important to community health as the U.S. Centers for Disease Control and Prevention’s (CDC) most recent sexually transmitted disease (STD) surveillance data reports that STDs in the U.S. have reached all-time highs for the sixth consecutive year. Most importantly, the DPP HIV-Syphilis System offers actionable information to better manage two of the most critical threats posed by syphilis infections: the potentially lethal mother to child transmission and the increased risk of contracting HIV.”

Mr. Eberly continued, “We would like to thank the FDA for their efforts in granting the CLIA waiver for the first point-of-care test to aid in the diagnosis of both HIV and syphilis from a single patient sample. We believe this is a significant step forward in the management of HIV and syphilis infections.”

Russell Rooms, DNP, APRN-C of Diversity Family Health, a private practice clinic specializing in the care of the LGBTQ+ community, further added, “The Chembio DPP HIV-Syphilis test has provided us with the ability to quickly screen patients for HIV and syphilis and allows us to be able to start treatment faster and differentiate between other disease processes. This means that we can better prevent the spread of these infections.”

Co-infection rates of HIV and syphilis are on the rise and, according to the CDC, individuals with an active syphilis infection have an estimated two- to five-fold increased risk of contracting HIV if exposed to that virus. The CDC has also reported that untreated syphilis in pregnant women who acquired the disease during the four years before delivery can lead to infection of the fetus in up to 80% of cases and may result in stillbirth or infant death in up to 40% of cases. Congenital syphilis is a preventable disease that could be significantly reduced through effective prenatal testing of women of childbearing age and treatment of infected pregnant women.

According to the U.S. Department of Health & Human Services, one in eight people living with HIV in the United States are unaware of their infection. Improving access to HIV testing can help more people learn their status so they can be connected to care and treatment. The CDC recommends that individuals at higher risk of HIV infection be tested at least annually.

Chembio’s DPP HIV-Syphilis System assists clinicians in diagnosing both HIV and syphilis while patients are still under care at the testing location. The DPP HIV-Syphilis System is a multiplex, single-use, 15-minute test that is designed, in combination with Chembio’s Micro Reader analyzer, to simultaneously detect antibodies to HIV types 1 and 2 and Treponema pallidum, the bacteria that causes syphilis. The test uses a small, 10-microliter sample of fingerstick whole blood, venous whole blood, or plasma. The DPP HIV-Syphilis System is highly sensitive and specific, has a built-in procedural control, can be stored at room temperature, and has a 24-month shelf life.

About the DPP Rapid Test Platform
Chembio’s proprietary DPP technology platform provides high-quality, rapid diagnostic results in 15 to 20 minutes using a small drop of blood from the fingertip or alternative samples. Through advanced multiplexing, the DPP platform can detect up to eight, distinct test results from a single patient sample, enabling greater clinical value than other rapid tests. For certain applications, Chembio’s easy-to-use, highly portable, battery-operated DPP Micro Reader optical analyzer then reports accurate results in approximately 15 seconds, making it well-suited for decentralized testing where real-time results enable patients to be clinically assessed while they are still on-site. Objective results produced by the DPP Micro Reader reduce the possibility of the types of human error that can be experienced in the visual interpretations required by many rapid tests.

Chembio’s portfolio of DPP-based point-of-care tests with FDA regulatory approvals include the DPP HIV-Syphilis System (PMA approved), DPP HIV 1/2 Assay (PMA approved and CLIA waived), DPP Zika IgM System (510(k)), and DPP Ebola Antigen System (EUA). Additionally, DPP-based tests have received regulatory approvals from the World Health Organization, CE-Mark, ANVISA, and other global organizations, where they aid in the detection and diagnosis of several other critical diseases and conditions.

All DPP tests are developed and manufactured in the United States and are the subject of a range of domestic and global patents and patents pending.
