Equipment Failures in Laboratories: Modern Approaches to Standards-Compliant Error Management
.avif)
Introduction
Equipment failures are among the most frequent causes of deviations, quality problems, and unplanned downtime in analytical and diagnostic laboratories. Whether in a GMP laboratory, a GLP laboratory, or in facilities accredited according to DIN EN ISO/IEC 17025 or ISO 15189, a structured approach to equipment failures is crucial for valid results and consistent data integrity.
Nevertheless, numerous laboratories still rely on Excel spreadsheets, decentralized documentation, or paper logbooks for test equipment management, measurement equipment monitoring, and measurement equipment administration. This approach entails significant risks: lack of versioning, no audit trails, inconsistent nomenclature, media breaks, and difficulties in trend analysis.
With increasing regulatory complexity, laboratory digitization, professional lab equipment management, laboratory management software and process-oriented test equipment management software are becoming increasingly important – not only to increase efficiency, but above all to ensure compliance.
What are equipment errors?
Equipment failures occur in measuring devices, testing equipment, laboratory instruments or automated systems and can be divided into several categories.
Technical error messages
This includes pump failures, valve malfunctions, pressure instabilities, and temperature drift in incubators or ovens. Sensor malfunctions such as UV lamp aging or detector drift also fall into this category. These technical malfunctions often require immediate action and can completely interrupt measurement operations.
Deviating measurements & drift
Unexpected standard deviations, implausible peaks or signals, and unstable baselines indicate systematic problems. These errors directly affect test equipment monitoring and calibration and may necessitate requalification.
Calibration error
Overdue calibration deadlines, missing documentation, or incorrectly applied calibration procedures pose a significant compliance risk. The requirements for calibration monitoring of test equipment are described in detail in DIN EN ISO IEC 17025 (also known as DIN ISO EN 17025, DIN EN ISO 17025, or DIN ISO IEC 17025) and must be consistently implemented.
Documentation errors (ALCOA principle)
Typical problems with paper-based or Excel-based documentation (test equipment monitoring in Excel) include missing timestamps, unclear assignments, subsequent changes without an audit trail, and missing person attribution. These deficiencies contradict the ALCOA principle and jeopardize data integrity.
User error
Unclear SOPs, incorrect parameterization, or a lack of training frequently lead to recurring errors. This category clearly demonstrates the importance of systematic laboratory management, structured knowledge management, and especially professional laboratory knowledge management for preventing operator errors.

An overview of the three standard systems
DIN EN ISO/IEC 17025
The focus is on measuring equipment monitoring, test equipment management including traceability, regular calibration and verification, and the documentation of deviations. Additionally, the assessment of measurement uncertainty is required. The handling of equipment failures must be documented in a traceable, assessable, and reproducible manner. The standard is also frequently referred to as DIN ISO 17025 or DIN EN ISO 17025.
DIN EN ISO 15189
Medical laboratories are subject to special requirements due to their direct impact on patient safety and the validity of diagnostic results. Stricter requirements apply to response times, evaluation, and CAPA (Corrective and Preventive Action), as well as a close link between equipment failures and clinical decisions.
GxP/GMP/GLP
GxP regulations require complete data integrity according to ALCOA+, uninterrupted audit trails, qualified suppliers, and documented equipment qualifications (IQ/OQ/PQ). Both GMP and GLP laboratories require structured test equipment management and documentation of GLP equipment with complete lifecycles. Errors must be traceably documented in tamper-proof digital systems.
Common basic logic of all norms
Despite their different focuses, all three systems follow a uniform core process:
- Detect errors
- Stop or isolate the device.
- Assessment (risk, validity, impact)
- Root Cause Analysis (RCA)
- Corrective measures
- Preventive Measures (CAPA)
- Effectiveness review
- Documentation in the audit trail
These steps form the basis for digital equipment management, structured test equipment management, professional test equipment management software, and modern laboratory management.
Modern solutions
Laboratory digitization
Digital systems automate documentation, link measurement data with logs and device status, and support standards-compliant processes. They eliminate media breaks and create end-to-end transparency.
Digital test equipment management software
Professional test equipment management software automatically monitors calibration deadlines, maintains complete histories, proactively identifies risks, and replaces error-prone Excel solutions. While free test equipment monitoring software can fill initial gaps, it quickly reaches its limits during GxP audits regarding audit trails, validation, and data integrity.
Automated measuring instrument monitoring
Modern systems integrate real-time data, maintenance cycles, calibration intervals, usage data, and drift analyses into a central platform. This enables a proactive rather than reactive maintenance strategy.
Predictive Maintenance
Analyzing usage data allows for the prediction of errors and deviations before they actually occur. This significantly reduces unplanned downtime and improves predictability.
Lab Equipment Management Systeme
These systems form the core of modern laboratory management with centralized asset management, tamper-proof audit trails, real-time status monitoring, and digital logbooks.

FAQ on Error Management in the Laboratory
What are the most common equipment-related errors in laboratories?
Pump failure, drift, sensor instability, temperature deviations, calibration errors, software bugs, operator error, documentation gaps, and incomplete logbooks.
What is the difference between measuring equipment monitoring and test equipment management?
Measuring instrument monitoring focuses on calibration and verification. Test equipment management additionally encompasses maintenance, qualification, history, documentation, and deployment planning.
What role does the ALCOA principle play in device failures?
It defines requirements for data integrity: attributable, legible, contemporaneous, original, and accurate. Error documentation must be complete, traceable, and tamper-proof.
Why are Excel spreadsheets no longer sufficient for monitoring test equipment?
Excel lacks audit trails, user management, automation, and integration with logbooks or maintenance cycles, and it is prone to errors. It does not meet the requirements for ISO 17025, ISO 15189, or GMP.
