How does a LIMS System Work

Understanding How a LIMS System Works: An Overview

A Laboratory Information Management System (LIMS) is an essential tool for data efficiency and operational management in laboratories. Providing a centralised platform for managing samples, data, workflows and regulatory compliance. The following is an overview of how does LIMS work:

Sample Reception and Registration

Reception: The reception process starts when a sample reaches the laboratory. This sample can come from multiple sources, such as hospitals, clinics, industries, research projects or private clients.

Registration: The sample is logged in the LIMS, assigning it a unique identifier. Details such as sample type, source, date and time of reception, and any relevant information for analysis are registered. It is important to comply with the regulations of each country where data are mandatory.

Sample Management

Follow up: Once registered, the LIMS tracks the sample through various stages of the analysis process. There is precise knowledge of the storage location, the people involved and the methodologies applied.

Sample Status: The system continuously updates the status of the sample, providing transparency on its progress and any pending actions.

Workflow Automation

Processes Definition: Workflows are defined in the LIMS to standardise laboratory procedures. This includes the sequence of processes to be followed, the equipment to be used and the quality criteria that applies.

Automation: LIMS allows these workflows to be automated, guiding users through each step and ensuring that the correct procedures and methodologies are followed.

Integration with analysers and measuring devices

Connections: LIMS allows connection to laboratory analysers and devices to collect data automatically. This eliminates manual data entry, reducing human error and increasing efficiency.

Data storage: The data generated by the analysers is automatically fed into LIMS, where it can be analysed and used to generate results reports.

Data and Results Management

Centralised Storage: All sample data and results are stored in a centralised database. Making easier the access and information management from anywhere and at any time and by any user with appropriate permissions.

Analysis and Reporting: El LIMS permite el análisis de datos y la generación de informes personalizados. Los usuarios pueden extraer información valiosa para la toma de decisiones y la mejora continua de los procesos.

Regulatory Compliance

Documentation: The LIMS has tools to help manage all the documentation needed to comply with quality regulations and standards, such as ISO 17025, ISO 15189, ISO 9001, GMP and GLP.

Auditories: Tools for internal and external audits are included, ensuring that all processes and data are traceable and can be verified.

Security and Access Control

Roles and Permissions: LIMS allows you to set roles and permissions for each user to control access to sensitive information and to the different displays and actions of the system.

Activities Log: LIMS maintains a log of all activities carried out, providing a detailed history of actions and modifications made to the system. The date and time, the user and the action undertaken are logged.

Customer Support and Updates

Sample Lifecycle Management within a LIMS System

Tracking from Initial Capture to Disposal in LIMS

One of the most critical aspects of sample management is the follow-up from the moment the sample is taken until it is finally disposed of. It is very important to know the status, location and actions taken or to be taken on each sample throughout its life cycle. For this reason, the LIMS must provide the laboratory with tools that allow this follow-up to be carried out.

The following processes can be distinguished throughout the life cycle of the sample:

Initial sample registration

The sample is received in the laboratory and registered in the LIMS system with a unique identifier along with the relevant data for the analysis. It is additionally bar-coded to ensure traceability.

Pre-analysis preparation and storage

It is possible to keep the sample in a pre-analytical storage until processing. The LIMS must allow tracking and retrieval of the sample at the time of processing.

Work planning

A LIMS should allow the organisation of laboratory work by means of request forms or worksheets by area, methodology, instrument or analyst.

Sample processing

Sample preparation according to the defined procedure and manual or automated processing by connecting to the analysers for user input without manual intervention by the analyst.

Results validation

The responsible person validates the results to ensure the accuracy and quality of the results and the further issuance of the report. A LIMS allows the report to be sent automatically or to be consulted on the laboratory's web portal.

Post-analysis storage

If the sample is not discarded immediately, it can be kept in the sample warehouse for the necessary period of time, which can be days or even years. There is full traceability for the entire length of storage.

Sample Disposal

At the end of the storage period the sample is discarded following the established protocols and regulations. Some LIMS allow you to set the storage length and generate visual alerts for samples that require to be discarded.

Audit and Traceability

The LIMS maintains a complete and auditable record of the entire sample lifecycle, from reception to disposal, allowing traceability to be retrieved for internal or external audits.

LIMS Role in Ensuring Data Integrity and Reducing Errors

LIMS is an essential tool to ensure data integrity and reduce errors in laboratory procedures.

Through processes automation and integrations with analysers manual data entry is avoided and more consistent and real-time processes are generated. Calibration and maintenance of the equipment can also be carried out, guaranteeing its correct performance.

The LIMS enables a traceability the system provides a complete log of the actions carried out, registering the user, date and time of completion. It also allows the stored data mining and analysis.

The integrity and results quality are assured through the validation processes and devices quality control. In addition, it allows access information to be managed through user roles and permissions.

In short, a LIMS significantly improves the accuracy, efficiency and reliability of laboratory operations. Implementing a proper LIMS helps to maintain high quality standards and ensure that data is accurate and secure at all times.

SOP Adherence and Accuracy through Protocol Execution in LIMS

The usage of a LIMS for the implementation of Standard Operating Procedures (SOPs) significantly improves the adherence and accuracy of protocols in the laboratory. Through automation of workflows, access control, verification and validation of procedures, and full traceability, the LIMS ensures that SOPs are followed consistently and accurately. In addition, it contributes to regulatory compliance and continuous improvement of laboratory performance. Choosing the right LIMS to maintain high standards of quality and efficiency in the laboratory is not an easy task.
