Your trusted standard for infectious disease surveillance
From our Statens Serum Institut roots (1902) to today’s SSI Diagnostica Group, we support the surveillance industry with reliable in-house manufactured serotyping reagents, robust bacterial strains, diagnostic kits, and scientific guidance across priority pathogens.
How we support laboratories involved in surveillance
Disease surveillance
Bacterial isolate confirmation and serotyping (e.g., Quellung/Neufeld for Pneumococcus; Kauffmann–White–Le Minor for Salmonella).
Serosurveillance
High‑quality antigens and reference materials suitable for lab‑developed assays for measurement of serotype-specific antibodies in serum samples (RUO).
