Diazyme Laboratories, Inc. Receives Second FDA EUA for COVID-19 Antibody Test

SAN DIEGO, CA - (August 17, 2020) Diazyme announces receiving FDA Emergency Use Authorization (EUA) letter for the Diazyme DZ-Lite SARS-CoV-2 IgM CLIA test. The Diazyme IgM test runs on the fully automated DZ-Lite 3000 Plus chemiluminescence analyzer.

"Diazyme continues to serve during the public health emergency with innovative products in COVID-19 serology (antibody) testing. The IgM test is typically used together with the IgG test for a more complete serology profile. The Diazyme DZ-Lite SARS-CoV-2 IgM test is highly sensitive and specific and does not cross-react when tested with an extensive list of interferents, including no cross reactivity to the common HKU1, OC43, NL63, 229E coronavirus strains. Recent independent performance studies* in peer-reviewed journals cite excellent results with Diazyme serology tests", said Dr. Chong Yuan, Managing Director of Diazyme Laboratories.
