What Ldbio Diagnostics does
LDBIO Diagnostics is a privately held French independent laboratory headquartered in Lyon, founded in 1997, that develops, manufactures, and markets in vitro diagnostic (IVD) tests specialized in parasitology and mycology. The company's product portfolio is organized into two technology platforms: a line of 13 Western Blot (immunoblot) confirmatory serological assays detecting IgG and/or IgM antibodies against pathogens including Toxoplasma, Aspergillus, Schistosoma, Trichinella, Echinococcus, Leishmania, Chagas, Cysticercosis, Fasciola, Toxocara, and Bird Fancier's Lung disease (PEO), plus a line of 4 immunochromatographic (ICT) rapid tests positioned for outpatient point-of-care screening of Toxoplasma, Aspergillus, Schistosoma, and PEO. The Western Blot assays use natural highly sensitive antigens, including proprietary Excretory-Secretory antigen preparations, and are intended as second-line confirmation of screening results; ICT tests are designed as unit tests for outpatient use. The company also offers reagents and equipment including the Uvibio B200.
The business operates a one-time-sale kit model with no disclosed pricing, taking orders via email and phone, and routes all commercial activity through a network of 21 dedicated regional distributors covering 22 countries across EMEA, APAC, MENA, and LATAM, with direct shipment via express carrier for uncovered geographies. End customers are clinical laboratories performing serological confirmation and screening, as well as specialist clinician groups (pulmonologists, respiratory/allergy specialists) requiring differentiation of sensitized from diseased subjects. The company holds ISO 13485:2016 certification, CE marking across its portfolio, and has transitioned all products to IVDR (EU) 2017/746 compliance, including Annex II List B attestation for toxoplasmosis reagents. Its Trichinella ES WB IgG is recommended by HAS (France), and its Western Blot tests were incorporated into the 2025 update of the French national recommendations for toxoplasmosis serological diagnosis.
The company is privately held with no disclosed parent, no institutional investors, and no funding history; Denis Limonne is identified as the website operator. No financial metrics — revenue, headcount, or unit volume — are publicly disclosed, and the company shows no AI/ML capability, no acquisitions, and no M&A activity in the available data.

Ldbio Diagnostics competitors and assessment
Company assessmentDirect peers
- Meridian Bioscience (Revvity): US specialty IVD manufacturer focused on infectious disease diagnostics, recently acquired by Revvity. Direct comparable in specialty infectious disease IVD positioning, although operating at larger scale than LDBIO.
- ELITech Group: French specialty IVD company with overlapping infectious disease serology and clinical chemistry menus. Similar founder-era origins in France and a comparable niche specialization in laboratory diagnostics.
- Omega Diagnostics: UK-headquartered specialty diagnostics company with infectious disease, food intolerance, and global health IVD products. Comparable in size, founder-era profile, and niche specialty IVD positioning.
- EUROIMMUN (PerkinElmer): German specialty IVD manufacturer focused on infectious disease and autoimmune serology, with deep Western blot, immunofluorescence, and ELISA menus. Closest direct comparable to LDBIO in technology, customer base (clinical labs), and niche focus on serological confirmation.
- Trinity Biotech: Ireland-based specialty IVD company with a portfolio centered on infectious disease serology (HIV, syphilis, TB) and HbA1c. Similar niche focus on infectious disease diagnostics and comparable specialty IVD business model.
- NovaTec Immundiagnostica: German specialty IVD manufacturer focused on infectious disease serology using ELISA and rapid test formats. Direct comparable in scale, technology, and target customer (clinical laboratories performing parasitology and infectious disease serology).
Regional players
- MBL (Medical & Biological Laboratories): Japanese specialty IVD and life science research company with infectious disease serology products. Comparable niche specialty focus but operates primarily in Japan/APAC rather than competing directly with LDBIO's EMEA-centric footprint.
Broad incumbents
- DiaSorin: Italian specialty IVD company with global reach, focused on immunoassay and molecular diagnostics. Comparable technology base (immunoassays) and Italian/French specialty IVD heritage, but broader menu and larger scale.
- Abbott Diagnostics: Global IVD major with broad infectious disease serology and rapid test portfolios. Competes with LDBIO for the same clinical lab customers, but from a position of vastly greater scale, automation, and global sales coverage.
- bioMérieux: French global leader in microbiology IVD, headquartered near Lyon. Overlaps with LDBIO in infectious disease diagnostics and parasitology/mycology, but operates across the full microbiology stack at vastly greater scale.
