A lab information management system is what a laboratory calls the place its samples live once they are more than a register can hold. The phrase covers everything from a hospital pathology platform with a hundred instrument interfaces to a spreadsheet with a login, and the difference between them is not the size of the vendor but what the system does with the record once it has it. This page is written for the manager of a small lab weighing the phrase for the first time: it explains what the system holds, why the figures it computes are the part that changes how the lab runs, and where the free sheets on this site do that computation today, without an account, from the lab's own numbers.
Six things the system holds
Samples, with their client, date, tests and status. Tests, with their method and their place in a batch. Results, with the analyst, the reviewer and the QC batch beside them. Reagent lots, with their expiry. Instruments, with their last and next calibration. Storage, to the freezer, rack, box and position. Every one of those is a column in a small lab's register today; the system links them so that a result knows its lot and its instrument, and an instrument knows every result that depended on its last calibration. That linkage is what an assessor working to ISO/IEC 17025 asks to see, and it is what a spreadsheet cannot show.
Why the arithmetic is the point
The record is necessary and it is also inert: nothing in a filing cabinet tells the manager whether next week's intake fits on the bench. The system earns its keep when it works the figures from the record: the analyst hours a week's samples need and the turnaround that gives, the full cost of a test and its margin, the QC share and its cost per result, the months the freezers have left, the boxes retention needs, the year's calibration cost, and the review hours the results need. Those seven are the free sheets on this site, and they are the honest specification of what a lab information management system should compute for a small lab before anyone discusses modules.
Where a small lab starts
With the intake sheet, because capacity decides everything else, then with the cost per test sheet, because the margin decides what any system can cost. The guide this page supports takes the four questions from there: the record, the computation, the printing and the export. Limslane Pro keeps the record at one flat price and prints under the lab's own name; an enterprise system keeps it with interfaces and modules a small lab may never use. The sheets are free whichever way the lab decides, and they need no account.
Questions people ask about lab information management system
What is the difference between a LIMS and a lab register?
The register holds the same fields; the system links them, so a result carries its reagent lot and its instrument's calibration, and a question about any of them is a lookup. It also computes: capacity, turnaround, cost, QC share, storage months, calibration cost.
Can a spreadsheet be a lab information management system?
It can hold the record and it can work the arithmetic, which is what the free sheets here do on the page. What it cannot do well is keep the links and the history as the lab grows, which is the job of the paid plan or an enterprise system.
Is the arithmetic on this site free?
Yes. Every sheet computes on the page with no account and no card. Limslane Pro adds the record: samples, results, lots and instruments kept against each other, reminders and export.
