SOLUBIO

Laboratoire Solubio is a private, independent testing laboratory headquartered at 1 Rue de l'Ardèche, 44800 Saint-Herblain, near Nantes in the Loire-Atlantique department of France. Founded in 2005 as a limited liability company (SARL), Solubio operates at the intersection of environmental hygiene, hospital hygiene, laboratory quality consulting, and professional training. The laboratory's roots lie in human health and clinical biology: its scientific team includes medical biologists (biologistes médicaux), a specialized quality engineer (ingénieur qualiticien spécialisé), and laboratory technicians trained in medical biology, giving it an unusually rigorous, clinically grounded perspective on environmental testing that distinguishes it from purely industrial contract laboratories.

Solubio's principal testing activity is microbiological and physico-chemical analysis of water across the full range of matrices encountered in environmental, institutional, and industrial settings. Water matrices routinely analyzed include hot sanitary water (Eau Chaude Sanitaire, ECS), borehole and groundwater (eau de forage), municipal distribution water, water intended for food-production use (eau à usage alimentaire), patient-care water in healthcare establishments (eau de soins en établissement de santé), industrial and stormwater discharges (eaux de rejet industrielles et pluviales), and cooling tower water (Eau de Tour Aéro-Réfrigérante, TAR). For each matrix the laboratory performs both microbiological culture and enumeration and physico-chemical parameter testing calibrated to the relevant French and European regulatory thresholds.

Legionella detection and quantification is a flagship competency at Solubio. The laboratory carries out the search for and identification of Legionella pneumophila in both hot sanitary water networks and cooling tower water—two systems subject to mandatory surveillance requirements under French public health legislation. Solubio holds COFRAC (Comité Français d'Accréditation) accreditation number 1-1649, covering water sampling for microbiological analysis on ECS and TAR systems and the detection and identification of Legionella species, including Legionella pneumophila. Because COFRAC Section 1 accreditations are issued against the requirements of NF EN ISO/IEC 17025—the internationally recognized standard for the technical competence and impartiality of testing and calibration laboratories—this accreditation confirms that Solubio's methods, equipment, personnel qualifications, and quality management system meet rigorous third-party-verified criteria.

Beyond water, Solubio extends its environmental testing scope to indoor air quality analysis. In partnership with TOXILABO, a Nantes-based laboratory specializing in occupational toxicology and volatile organic compound (COV) and gas analysis, Solubio offers structured indoor air quality monitoring campaigns. This collaboration combines Solubio's microbiological expertise—relevant to biological airborne contaminants such as molds and bacteria—with TOXILABO's chemical and gas-phase analytical capabilities, enabling clients to address both biological and chemical air-quality risks within a single coordinated program. Facilities such as hospitals, schools, commercial buildings, and industrial workplaces can use these services to meet occupational health obligations and improve occupant safety.

As a recognized advisory body (Organisme de Conseil), Solubio provides specialized consulting services to Medical Biology Laboratories (Laboratoires de Biologie Médicale, LBM) throughout France. The firm supports these institutions in establishing, documenting, and maintaining their quality management systems in compliance with the regulatory requirements of NF EN ISO 15189, the international standard governing quality and competence in medical and clinical laboratories. This advisory practice makes Solubio unusual among environmental testing laboratories: it not only conducts accredited analyses on behalf of clients but also helps peer institutions achieve and sustain their own accreditation and satisfy French health-authority inspection requirements. Services in this area include gap analyses, internal audit support, procedure documentation, and ongoing quality system monitoring.

Solubio is registered as an official training organization (Organisme de Formation) under French administrative number 55 44 05621 44. Its vocational training catalogue addresses the two most regulated areas of its testing specialization. First, courses on Legionella risk management cover the identification and mitigation of legionellosis risk in both hot sanitary water networks (ECS) and cooling tower systems (TAR), with content adapted to building and facility managers, hospital technical teams, and quality officers. Second, practical sampling training teaches correct field sampling procedures specifically for Legionella analysis from ECS and TAR systems, equipping technicians and maintenance staff to obtain compliant, representative samples whose integrity supports valid laboratory results and defensible regulatory submissions.

Laboratoire Solubio's integrated model—combining COFRAC-accredited ISO 17025 water and air testing, NF EN ISO 15189 quality-system consulting for medical laboratories, and certified professional training—positions it as a comprehensive partner for organizations with demanding environmental hygiene and water-safety obligations. Its client base spans hospitals and healthcare networks requiring Legionella surveillance and water quality assurance; industrial facilities with cooling towers subject to compulsory microbiological monitoring; food production and processing sites needing potable and process water testing; municipal water distributors; and medical biology laboratories seeking external quality management expertise. This multi-service depth, backed by accredited analytical methods and a team with clinical biology credentials, makes Solubio a credible and specialized testing partner for the French environmental hygiene sector.
