Chembio Diagnostics, Inc. announced that the delivery schedule for shipments of DPP SARS-COV-2 Antigen Tests under its July 2021 purchase order from Bio Manguinhos has been extended into March 2021. As the result of a portion of the shipments now being deliverable after year end, Chembio believes it now has the opportunity to fulfill all of the $28.3 million order. Chembio?s delivery of tests covered by the purchase order, however, continues to be negatively affected by limitations of Chembio?s supply chain, staffing, and liquidity, and other matters outside Chembio?s control. The DPP SARS-CoV-2 Antigen test is designed to detect the SARS-CoV-2 antigen, which indicates an active COVID-19. infection, in only 20 minutes using a minimally invasive nasal swab.
