Colloidal Gold has been approved as a diagnostic test for the novel coronavirus (COVID-19) in China by the NMPA (formerly the China FDA) and in Europe under a CE Mark. Todos will be responsible for obtaining U.S. Food and Drug Administration (FDA) approval and plans to do so under the Emergency Use Authorization Program.

Shanghai has shipped test kits for validation by Todos. During the four-week validation process, Todos intends to place its first purchase order based upon the market demand identified. Shanghai currently has 500,000 Colloidal Gold test kits in stock, and has indicated to Todos that it can manufacture up to 300,000 test kits per day to help meet the demand in the U.S., given that demand for test kits in China has begun to decline.
