The LIMS is where the lab's record of every sample lives
A laboratory information management system tracks samples from receipt to result. It holds the chain of custody, the test requests, the instrument output, and the record a regulator or an auditor will ask for later. When it does not fit how the lab works, people work around it, and the record stops being trustworthy.
What a LIMS has to handle
Sample tracking
Every sample gets an identity at receipt and keeps it through aliquoting, storage, testing, and disposal. Barcodes, locations, and parent to child relationships have to stay consistent across all of it.
Chain of custody
Who handled the sample, when, and what they did. The record has to hold up when someone asks months later why a result is what it is.
Instrument integration
Results come off sequencers, analyzers, and plate readers in their own formats. The LIMS has to take that output in without retyping, and flag what does not parse.
Workflows and test requests
Which tests run on which sample, in what order, with what acceptance criteria. Labs change their methods, so the workflow definition has to be editable without a rebuild.
Audit trail and electronic records
In a regulated lab the LIMS is an electronic record system. Changes are attributed, time stamped, and retained, and the system has to be validated for its intended use.
Connections to other systems
ELN, ERP, inventory, reporting, and the pipelines that consume the results. A LIMS that stands alone becomes a copy and paste step for someone.
Three kinds of LIMS work
A LIMS built for the lab
When commercial systems do not fit, or the lab's process is the product, a purpose built LIMS. Designed around the sample lifecycle the lab actually runs, with the integrations and record keeping that lab needs.
Keeping a LIMS in production
A LIMS in daily use needs someone who knows it. Fixes, upgrades, changes to instruments and integrations, and the change control that goes with a validated system.
Adapting a LIMS to how the lab works
New workflows, new sample types, new instruments, new reports. Changes made so the lab stops working around the system, without breaking what already runs.
If you are deciding between building, replacing, or adapting a LIMS, we can talk through what each would involve for your lab.
