# Laboratory execution systems (LES) Software that guides a lab analyst step by step through a validated test method — enforcing sequence, capturing instrument data automatically and generating an audit-trailed electronic record — replacing the paper worksheet as the way regulated QC and R&D labs prove a test was actually run as written. Source: https://en.bioecon.ru/technology/laboratory-execution-systems/ Updated: 2026-08-18 ## Overview and value chain Markers: [EC: Guided, audit-trailed execution of validated laboratory test methods | OECD: Biopharmaceutical manufacturing & quality | Regulator: FDA (US), EMA (EU), NMPA (China)] A laboratory execution system (LES) walks an analyst through a validated test method on screen, step by step, enforcing the correct sequence, pulling live readings from connected instruments instead of a manual transcription, and building the electronic record as the test runs rather than after the fact. LabVantage bundles LES as part of a combined LIMS/ELN/SDMS informatics suite and in 2026 added LabVantage CORTEX, extending the platform with agentic AI and cloud-native automation for AI-driven laboratory operations. LabWare, serving over 10,000 laboratories in more than 125 countries, ships LES-style guided workflows inside its LIMS. STARLIMS — founded in Israel in 1986, later owned by Abbott and now run independently under Francisco Partners — offers a cloud LIMS with guided execution aimed at batch-manufacturing QC labs. Dassault Systèmes' BIOVIA ONE Lab is the lab-informatics layer of a broader scientific-innovation platform, connecting guided execution to molecular modelling, formulation design and manufacturing analytics on one data model. Thermo Fisher's SampleManager LIMS ships a cloud-hosted option built for regulated environments, keeping guided execution and data-integrity controls in a managed cloud rather than on-premises. PerkinElmer's LabWorks bundles LIMS, ELN and SDMS as a combined solution and is actively distributed in China through regional instrumentation partners. The key directions of laboratory execution systems are: 1. **Step-enforced method guidance:** the system presents the validated method one step at a time and will not let an analyst skip, reorder or bypass a step without a documented deviation. 2. **Automated instrument data capture:** readings pull directly from connected balances, pH meters, chromatographs and other lab instruments into the electronic record, removing manual transcription errors. 3. **Real-time electronic record generation:** the audit-trailed record builds itself as the test runs, rather than being reconstructed from a paper worksheet after the fact. 4. **Suite convergence with LIMS/ELN/SDMS:** LES increasingly ships as a module inside a broader informatics suite rather than as a standalone product, sharing one data model with sample tracking, notebook and raw-data-archiving functions. ### Sectoral value chain ``` [Validated method authoring] ──> [Step-guided execution] ──> [Automated instrument capture] │ (Real-time record build) │ [QA review & release] <──── [Deviation handling] <─── [Audit-trail generation] ``` ### Value chain levels | Level | Description | Key inputs/outputs | |:---|:---|:---| | **Method authoring** | Encoding a validated test method as a structured, versioned sequence of steps inside the system. | **In:** Validated SOP/method document.

introduced LabVantage CORTEX in 2026, adding agentic AI and cloud-native automation to guided lab operations. - **LabWare:** serves more than 10,000 laboratories in over 125 countries with LES-style guided-execution workflows inside its LIMS, counting GSK, Pfizer and other regulated manufacturers among its customers. - **STARLIMS:** an Abbott-owned brand relaunched independently under Francisco Partners in 2021, offering a cloud LIMS with guided execution ("QM Essentials") targeted at small-to-medium batch-manufacturing QC labs. - **Thermo Fisher SampleManager LIMS:** a cloud-hosted LIMS built specifically for regulated environments, pairing guided execution with data-integrity controls in a managed-cloud deployment model. --- ## CN China is covered through the distribution footprint of global vendors rather than a live-screened Chinese-headquartered LES vendor: no domestic LES/LIMS company confirmed by a live 2026 source was found during this screen. ### PerkinElmer LabWorks distributed through Chinese instrumentation partners - **PerkinElmer LabWorks:** a combined LIMS/ELN/SDMS solution actively marketed and distributed in China by regional laboratory-instrumentation resellers, giving Chinese pharmaceutical and QC labs access to guided test-execution workflows through the same platform sold globally. - **Domestic gap:** the category in China is served by distributed global platforms and by manufacturing-execution-system vendors adjacent to (but distinct from) laboratory-specific guided execution, rather than by a dedicated Chinese LES SaaS vendor. --- ## EU The European Union's leading vendor treats laboratory execution as one module inside a much larger scientific-innovation platform rather than as a dedicated point product. ### BIOVIA ONE Lab's connection to molecular modelling and manufacturing analytics - **Dassault Systèmes BIOVIA:** ONE Lab is the lab-informatics layer of a comprehensive platform that also spans molecular modelling, formulation design, manufacturing analytics and regulatory quality management, all on one RDF data model — positioned against dedicated LIMS competitors as a broader R&D-to-manufacturing data backbone rather than a like-for-like LES swap-in. --- ## Leading companies and research institutes | Company / Institute | Country | Key products / platforms | Tech features | Status 2026 | |:---|:---|:---|:---|:---| | **LabVantage Solutions** | 🇺🇸 USA | LabVantage LIMS/ELN/SDMS, *CORTEX* | Agentic AI, cloud-native automation | commercial | | **LabWare** | 🇺🇸 USA | LabWare LIMS | 10,000+ labs, 125+ countries | commercial | | **STARLIMS** | 🇺🇸 USA | *QM Essentials* cloud LIMS | SMB batch-manufacturing focus | commercial | | **Dassault Systèmes BIOVIA** | 🇫🇷 France | *ONE Lab* | Unified RDF data model, molecular-to-manufacturing | commercial | | **Thermo Fisher SampleManager** | 🇺🇸 USA | *SampleManager LIMS* cloud-hosted | Managed cloud, regulated-environment focus | commercial | | **PerkinElmer LabWorks** | 🇨🇳 China (distribution) | *LabWorks* LIMS/ELN/SDMS | Distributed via regional China resellers | commercial | --- ## Tech stack and innovations The laboratory execution system technology stack is converging guided step-execution with the broader informatics suite around it: 1. **Guided, validated-method execution:** - LES engines block skipped or reordered steps and route deviations for documented resolution, replacing paper-worksheet discipline with software enforcement. 2. **Automated instrument integration:** - Direct capture from balances, pH meters and chromatographs removes manual transcription as a source of data-integrity findings. 3. **Suite convergence and agentic AI:** - Vendors increasingly ship LES as one module of a combined LIMS/ELN/SDMS platform; 2026 saw the first agentic-AI extensions (LabVantage CORTEX) layered on top of guided execution. --- ## Value chains and production pipelines ### Industrial pipeline for guided laboratory test execution ``` ┌───────────────────────────┐ ┌───────────────────────────┐ │ 1.
