Ultralab srl

Ultralab srl is an accredited Italian testing laboratory (laboratorio accreditato) specializing in microbiological analyses of environmental matrices, water systems, and surfaces. Holding ISO/IEC 17025 accreditation issued by ACCREDIA—Italy's national accreditation body—Ultralab satisfies both the technical requirements and the quality management system requirements necessary to produce technically valid test and calibration results. The laboratory's primary scientific focus is biological risk assessment, with deep expertise in detecting, enumerating, and monitoring Legionella pneumophila and related species across complex water and air environments. Its scope of work spans routine compliance monitoring, investigative risk assessments, and post-remediation verification for clients throughout Italy.

Ultralab's flagship service is Legionella detection and quantification, performed in accordance with the internationally recognized standard UNI EN ISO 11731:2017 (Water quality—Enumeration of Legionella). The laboratory conducts full investigations of water distribution and hydraulic systems, mapping the network, identifying critical control points, and documenting sites where Legionella colonization risk is elevated. Results are interpreted against the thresholds established by Italian law and European directives, and the laboratory provides written remediation (bonifica) recommendations specifying the most appropriate corrective interventions to bring colony counts back within legal limits. This end-to-end investigative capability distinguishes Ultralab from laboratories that issue numerical results alone.

The water testing portfolio covers four distinct matrix categories. Sanitary and potable water analysis targets samples drawn from shower heads, taps, sinks, and domestic hot-water boilers—the most common exposure routes in residential, hospitality, and healthcare settings. Industrial water analysis is designed for high-interference environments such as cooling towers and industrial process water circuits, where elevated background microbial flora demands specialized enumeration protocols capable of distinguishing target organisms from interfering species. Surface water and discharge water analysis addresses streams, canals, and ponds characterized by high contaminating flora loads. Swimming pool, tank, and jacuzzi analysis covers both small and large recirculating systems, including thermal spas, hydrotherapy pools, and wellness facilities, where continuous water recirculation creates persistent Legionella colonization risk.

Beyond liquid matrices, Ultralab extends its microbiological testing to surfaces and indoor air. Surface sampling is conducted on stagnant water collected from the humidification tanks of air handling units (UTA) and from heating and air-conditioning components such as fan coils, as well as via swab sampling for biofilm present in pools, jacuzzis, and saunas. Air testing is performed through active sampling of aerosolized water droplets dispersed by ventilation and air-conditioning systems—a clinically significant transmission pathway for Legionella and other respiratory pathogens. This multi-matrix approach enables clients to obtain a holistic microbiological risk profile of a facility—water, surfaces, and air—within a single contracted engagement rather than coordinating multiple specialist providers.

The laboratory operates in full conformity with Italy's national Legionella Guidelines and the Directive D.Lgs. 18/2023, which transposes the updated EU Drinking Water Directive into Italian national law. Beyond reporting raw analytical data, Ultralab monitors key microbiological parameters over time, benchmarks results against statutory limits, identifies trends indicating deteriorating water hygiene, and advises facility managers on the selection and sequencing of chemical or thermal remediation treatments. This consultative, monitoring-based model supports clients through the complete regulatory cycle—initial risk assessment, periodic surveillance, and post-intervention verification—positioning the laboratory as a long-term technical partner rather than a one-off service provider.

Quality assurance and analytical impartiality are embedded at every stage of Ultralab's operations. The laboratory's ACCREDIA-accredited status under ISO/IEC 17025 means that all activities—from sample receipt and chain-of-custody coding through analysis, data review, and formal report issuance—are governed by documented internal procedures within a structured Quality Management System. Sample coding protocols are specifically designed to protect confidentiality and prevent result bias. Every six months, Ultralab participates in mandatory interlaboratory proficiency testing (prove valutative interlaboratorio), an independent benchmarking exercise that verifies the accuracy, consistency, and reproducibility of results against peer laboratories. The laboratory also invests continuously in state-of-the-art instrumentation to ensure both analytical precision and fast turnaround times, and all technical staff undergo continuous professional development to stay current with evolving standards and regulatory methodologies.

Ultralab's accredited microbiological testing services are relevant to a wide cross-section of industries where water hygiene and Legionella control are statutory obligations or operational risk priorities. Core client sectors include hotels and hospitality venues, hospitals and care homes, industrial manufacturing plants with cooling water circuits, sports and wellness centers with pools or saunas, commercial and residential building management companies, and public utilities responsible for drinking water distribution networks. With ACCREDIA accreditation, validated methods conforming to ISO and UNI EN ISO standards, transparent and impartial reporting, and a team committed to scientific rigor, Ultralab srl provides clients in Italy with a fully compliant and technically authoritative microbiological testing partnership.
