What is a LIMS? A 2026 primer
A Laboratory Information Management System (LIMS) is the operational software a laboratory uses to manage samples, run tests, validate results, generate patient reports, bill for the work, and prove to regulators that every step happened correctly. It is the system of record for a lab's day-to-day operations — from the moment a patient walks in (or a sample arrives by courier) to the moment the result is released and the invoice is paid. A LIMS is not a clinical decision-support tool, not a generic ERP, and not the same thing as an Electronic Medical Record (EMR) — though it integrates with all three. This post is the definitional primer: what a LIMS actually does, the terms-of-art that distinguish it from adjacent systems, and the modern cloud-multi-tenant patterns that have become the 2026 default.
