Laboratory information management systems, LIMS for short, are a category with two ends and a long middle. At one end sits the enterprise platform sold by tender to regulated laboratories, with instrument interfaces, validated methods and an implementation project measured in months. At the other sits the small lab's spreadsheet, which holds the same record without the links. The long middle is where most small laboratories actually buy, and it is priced by the module. This page reads the category from the small lab's side: which parts of a LIMS the bench uses in its first year, which parts are bought and never opened, and how to put a vendor's module list against the figures the lab already works by hand, which the free sheets on this site compute with no account.
The modules, and which a small lab opens
Sample management, batch and QC, results and review, inventory of reagents and consumables, instruments and calibration, storage, reporting, billing, and instrument interfaces. A small analytical lab opens the first six in its first year and rarely the last three: reports are still built from templates, invoices come from the accounts package, and the two instruments that could be interfaced are entered by hand faster than the interface can be validated. ASTM's informatics guide lists the functions a system may carry; it does not say a small lab needs all of them, and the vendor's proposal should be read with that list in one hand.
The figures that size the purchase
Three numbers decide whether any system in the category pays: the analyst hours a week's samples need against the bench, the margin a test earns at the price charged, and the hours the system would save in review, storage lookups and calibration chasing. The intake sheet, the cost per test sheet and the results review sheet on this site work the first two and half of the third. A vendor's annual price divided by the year's tests is the cost per test the system adds, and it has to fit inside the margin the cost sheet returns with room for everything else.
Reading a proposal against the sheets
Put the vendor's module list beside the seven sheets: intake and turnaround, results review, cost per test, quality control, storage, retention, calibration. A module that maps to a sheet is one the bench will use; a module that maps to nothing is a question for the vendor. Then ask for the export. The guide this page supports walks that reading in detail. Limslane Pro keeps the record the seven sheets produce at one flat price; the category's enterprise end keeps it with the interfaces a small lab may never validate.
Questions people ask about laboratory information management systems lims
What are laboratory information management systems?
Software that keeps a laboratory's samples, tests, results, reagent lots, instruments and storage as one linked record and works the figures that record allows. The category runs from enterprise platforms sold by tender to a small lab's spreadsheet; the sheets on this site work the arithmetic free of either.
Which LIMS modules does a small lab actually use?
Sample management, batch and QC, results and review, reagent inventory, instruments and calibration, and storage, in the first year. Reporting, billing and instrument interfaces are usually bought and opened later or never; strike them from a first proposal and ask for the price again.
How do I compare LIMS pricing to my lab's margin?
Divide the vendor's annual price by the year's tests for the cost per test the system adds, and put it against the margin the free cost per test sheet returns from your own reagent, labour and overhead figures.
