What Is a LIMS? Laboratory Information Management System Guide

As a laboratory's workload grows, so does its record keeping. Quotes, received instruments and samples, measurement data, reports and certificates pile up in different places over time. When some of it lives in Excel files, some in e-mail threads and some on paper forms, finding the right information becomes harder than it should be. A LIMS (Laboratory Information Management System) is the type of software designed to bring these scattered records under one roof. In this article we look at what a LIMS is, which problems it solves, and what to consider when choosing one for a calibration or testing laboratory.

What is a LIMS?

LIMS stands for Laboratory Information Management System. In the broadest sense, it is laboratory software that records and manages the whole process, from the moment a job is accepted to the moment the result reaches the customer. Sample or instrument details, the work performed, the person who performed it and the resulting document are kept in the same system and linked to one another. This makes the history of a record traceable later and removes the need to retype the same information in different places.

Which problems does it solve in the laboratory?

Teams that run their work through disconnected files tend to face similar difficulties. A well-designed LIMS helps reduce a good share of them.

• Scattered records: When the same information is kept in several places, it becomes unclear which copy is current.
• Hard-to-follow progress: The status of a job is only known when someone asks.
• Manual entry errors: Moving data from one file to another invites a wrong row or a wrong customer.
• Delayed delivery: A document waiting for approval goes unnoticed and the process takes longer than necessary.
• Missing traceability: It cannot be shown afterwards who created or changed a record, and when.

ISO/IEC 17025 is the standard that defines the general requirements for the competence of laboratories, and traceable records are expected within that framework. Software alone does not guarantee conformity, but it does make record keeping and traceability easier.

What to expect from a LIMS in a calibration laboratory

The work of a calibration laboratory revolves around instruments. A calibration LIMS is therefore expected to follow the flow without gaps, from quotation and instrument receipt through task planning to the preparation, review and approval of the certificate. Tracking the calibration, maintenance and checks of the laboratory's own reference instruments matters just as much. For example, KALDATA Calibration Laboratory Management Software shows certificate stages in separate tabs with counters, and it does not add a reference instrument with an expired calibration to a certificate, warning the user instead. For accredited laboratories, being able to carry out TÜRKAK TBDS operations from within the software also makes daily work easier.

What to expect from a LIMS in a testing laboratory

In a testing laboratory the focus is the sample. Receiving the sample, scheduling the test date, entering raw data and getting the report approved and delivered to the customer should all be visible in a single flow. The Testing Laboratory Software for construction materials laboratories is one example of this. Request, sample and report numbers are generated automatically, test dates for concrete samples are scheduled automatically and the daily work list is ready when the team arrives. Reports that can be verified with a QR code, and a portal where customers reach their own completed reports, make communication with customers easier as well.

General-purpose LIMS versus field-specific software

General-purpose LIMS products are designed to serve many different kinds of laboratories. That flexibility is an advantage, but adapting the system to a laboratory's workflow may require additional configuration and time. Field-specific laboratory software is built around the terms, documents and work order of one particular type of laboratory. Concepts such as certificate and reference instrument for a calibration laboratory, or sample and report for a testing laboratory, are in place from the start. Which option fits better depends on the size of the laboratory, its field of work and its expectations.

What to look for when choosing a LIMS

When evaluating software, it is more useful to look at how well it fits your daily work than at the length of its feature list. The questions below can be a good starting point.

• Does the software cover your laboratory's field of work and document types?
• Can pending jobs and workflow stages be seen at a glance?
• Can preparation, review and approval steps be followed separately?
• Can you keep using your existing Excel templates?
• Are there warnings and checks that prevent user errors?
• Is mobile use available for the team working in the field?
• Do the records answer the question of who did what, and when?

The most reliable evaluation is to follow a real example from your own workflow through the software from start to finish. That way you judge the fit from your own work rather than from promotional text.

Conclusion

A LIMS is a tool that brings a laboratory's records together, makes the workflow visible and helps reduce errors. The right choice is the solution that best fits your type of laboratory and the way you work every day. For calibration laboratories you can explore KALDATA Calibration Laboratory Management Software, and for construction materials laboratories the Testing Laboratory Software.
