comprise assays to detect CMV and Syphilis. We expect to follow our initial MosaiQ SDS Microarray launch with the launch of a range of additional MosaiQ SDS II Microarrays incorporating all remaining mandated serological disease screening assays, depending upon the final application for the product. Based on historical annual blood donations collected by our key target donor testing customers, we estimate that the potential market for MosaiQ microarrays (for blood grouping, serological disease screening and molecular disease screening) should exceed 100 million microarrays per annum following receipt of applicable regulatory clearances and approvals for MosaiQ.
We also believe that MosaiQ may have the potential for use beyond transfusion diagnostics in the larger clinical diagnostics market, and are evaluating the potential for our technology as a platform for diagnosis and monitoring of other disease states. We have identified opportunities for future partnership and development in relation to disease states for which a broad array of tests are required using multiple testing modalities for a single diagnosis or for ongoing therapy monitoring.
We have a proven track record and significant expertise in product development, manufacturing and quality assurance, tailored to the highly regulated transfusion diagnostics market. We currently derive revenue from a portfolio of products used for blood grouping, as well as whole blood controls used daily for quality assurance testing of third-party blood grouping instruments. We have introduced a range of U.S. Food and Drug Administration, or FDA, licensed products in the United States under the Quotient brand, which we sell directly to donor testing laboratories, hospitals and independent patient testing laboratories. We also develop, manufacture and sell conventional reagent products to original equipment manufacturers, or OEMs, such as Ortho-Clinical Diagnostics, Inc., or Ortho,Bio-Rad Laboratories, Inc. and Grifols S.A. In April 2019, the FDA licensed a range of rare anti-sera conventional reagents products for sale in the United States and in July 2019, the FDA licensed a range of conventional reagents manufactured by us for use on an instrument testing platform commercialized by Ortho.
We are developing additional conventional reagent products for our OEM customers and for sale directly in the United States under the Quotient brand.
