What Check Diagnostics does

Check Diagnostics GmbH is a privately held German specialty distributor of in-vitro diagnostic products headquartered in Bad Oldesloe, Schleswig-Holstein, operating since 2000 with a workforce of approximately 15–20 staff organized around sales, technical service, order processing, and warehouse functions. The company does not manufacture its own products; instead it curates and distributes a multi-vendor portfolio covering pre-analytical sampling systems (swabs, transport media, surface sampling devices), molecular diagnostics reagents and controls, microbiology consumables, and infectious disease serology instruments and assays. Core capital equipment in the portfolio includes the VirClia Lotus automated chemiluminescence immunoassay analyzer (90+ monotest parameters, random access, STAT function, LIS integration), the VirPLEX MiniLab closed multiplex PCR system (up to 15 targets per cartridge), and the MycoDDR Trident specimen preparation system for mycobacterial diagnostics.

The company serves four end segments — human medical diagnostic laboratories, veterinary laboratories (including poultry monitoring for Salmonella/Campylobacter), food industry laboratories (hygiene monitoring, HACCP/IFS/BRC support), and specialized reference laboratories and university clinics — exclusively within Germany. Distribution is direct through a regionally segmented field force (territory managers for North, East/West, Southwest, Southeast), supported by Medical Product Advisors and a Key Account Manager, complemented by a Wissensportal knowledge site, downloadable product documentation, and presence at German industry congresses. Revenue is generated through hardware and consumable sales; pricing is not publicly disclosed and no third-party distribution agreements or revenue figures are published.
