Company profile
researched Aug 2026BÜHLMANN Laboratories AG is a Swiss in vitro diagnostics (IVD) company headquartered at Baselstrasse 55 in Schönenbuch, in the Basel area. It discovers, develops and manufactures chemistry and immunological assays for both IVD and research-use-only (RUO) applications, sold to clinical, discovery and basic-science laboratories. The company describes itself as fully independent, medium-sized and family owned.
Its portfolio is organised around several product lines. In gastroenterology, BÜHLMANN offers fecal calprotectin assays (BÜHLMANN fCAL turbo turbidimetric and fCAL ELISA), fecal pancreatic elastase (fPELA turbo), therapeutic drug monitoring for biologics used in chronic inflammatory disease, the Quantum Blue point-of-care rapid test platform with dedicated readers, the IBDoc home-test application, and CALEX/CALEX Cap sample extraction and collection devices. Other lines cover clinical chemistry (ACE kinetic, ACE high sensitive, GHB enzymatic assay, serum calprotectin), autoimmunity (MRP8/14 serum calprotectin, CIC and anti-C1q antibody ELISAs), cellular allergy (Flow CAST for basophil activation testing, CAST ELISA and CAST allergens), kinase inhibition assays, neuroimmunology (GanglioCombi MAG, GanglioCombi Light, anti-MAG, anti-GM1 and anti-SGPG antibody ELISAs) and a specialty Amanitin ELISA for detecting alpha- and gamma-amanitin in urine after Amanita mushroom ingestion. The company also distributes molecular diagnostic products from third parties including Seegene, EntroGen and Cerca Biotech (MammaTyper).
Several products are marketed as FDA IVD in the United States, including CALEX Cap, fCAL turbo, fCAL ELISA, fPELA turbo, ACE kinetic and the CIC-C1q ELISA. The quality management system is described as ISO 9001:2008 and ISO 13485:2003 certified, with products manufactured to GMP standards.

▸Full profile — market position, technology, go-to-market, geography, history
Market position
Positioned as a leading supplier of calprotectin testing, offering a broad range spanning high-throughput automated turbidimetric and ELISA assays through point-of-care and home testing, and as a niche supplier of basophil activation and anti-ganglioside screening ELISAs.
Breadth of the calprotectin assay range across laboratory, point-of-care and home-testing formats; the Flow CAST basophil activation test group where specific IgE testing is diagnostically limited; and the GanglioCombi products described as screening ELISAs for anti-ganglioside testing.
Technology
Assay technologies include turbidimetric immunoassays for random-access clinical chemistry analysers, ELISA formats, lateral-flow point-of-care tests read on the Quantum Blue Reader (2nd and 3rd generation), flow-cytometry-based basophil activation testing (Flow CAST), the CALEX/CALEX Cap stool extraction devices, and the IBDoc smartphone-based home test with the CalApp application.
Go-to-market
Direct sales and support through local teams and national subsidiaries, a global distributor network, product support and remote support services, and presence at clinical laboratory and specialty medical congresses such as ADLM, EAACI, DGRh, PReS, DGKL-DKLM, JFBM, UEGW and IFCC WorldLab.
Clinical diagnostic laboratories, hospital and routine laboratories, and discovery and basic-science research laboratories; the IBDoc application extends calprotectin testing to patient home use.
