DiaSorin S.p.A.: core business model

DiaSorin S.p.A. operates as a fully integrated in-vitro diagnostics company, developing, manufacturing, and commercializing reagent kits and instruments worldwide. The firm specializes in immunodiagnostics and molecular diagnostics platforms, serving hospitals, laboratories, and reference centers. Its business model emphasizes proprietary technologies like chemiluminescence for high-sensitivity assays and real-time PCR for molecular testing.

Founded in 1974 and headquartered in Saluggia, Italy, DiaSorin has grown through organic development and strategic acquisitions, such as the 2018 purchase of ELITechGroup's molecular diagnostics business. This has positioned it as a leader in transplant diagnostics and infectious disease testing. The company's vertical integration allows control over the entire diagnostic workflow, from instrument development to assay commercialization.

For US investors, DiaSorin's Nasdaq ADR (DSRLY) provides direct access to its performance, with significant revenue from North American sales. The ADR facilitates trading in USD, aligning with US market hours and regulatory standards.

DiaSorin's revenue is primarily driven by its LIAISON and QIAcube platforms. The LIAISON family accounts for over 60% of sales, offering automated analyzers for vitamin D, bone markers, and infectious diseases like COVID-19 and hepatitis. Molecular diagnostics, powered by the Walker and LIAISON MDX systems, contribute growing shares through tests for HPV, CMV, and TB.
