What is LIMS in a laboratory? Four letters for laboratory information management system, and behind them one idea: that a laboratory's samples, and everything that happens to them, are kept as one record that knows its own parts. The word laboratory says where; information says what is kept, which is every fact about a sample from the client who sent it to the freezer position it ends in; management says what is done with it, which is working the figures the bench runs on; and system says it is one linked structure rather than a register, a freezer map and a spreadsheet that agree by luck. This page unpacks the acronym letter by letter for a small lab and shows where the free sheets on this site do the management part today, with no account.
L and I: the laboratory's information
The information is the sample record: client, chain of custody, tests, batch, controls, instrument, reagent lot, result, reviewer, report, storage position, retention date. Every small lab keeps all of it already, in a register and a set of labels, and ASTM's laboratory informatics guide describes the same fields as the functions of a system. The difference a LIMS makes to the L and the I is that the fields are linked, so a result knows its instrument's calibration and the instrument knows every result that depended on it.
M: the management, which is arithmetic
Management is what is done with the information, and on a bench it is arithmetic: the analyst hours the week's samples need and the turnaround that gives; the cost of a test and its margin; the share of the bench the controls take; the months the freezers have left; the boxes retention needs; the year's calibration cost; the hours the results need in review. The seven sheets on this site are the M of LIMS worked on the page from the lab's own inputs, which is the fairest way to see what a system would do before buying one.
S: one system rather than three files
The system part is the linkage: a sample's whole chain on one screen, a batch's controls beside every result it produced, an instrument's calibration beside every result since. ISO/IEC 17025 asks a testing laboratory to be able to show exactly that chain. The guide this page supports walks how a small lab chooses the system that fits. Limslane Pro keeps the S for a small lab at one flat price; the sheets do the M for free.
Questions people ask about what is lims in laboratory
What does LIMS stand for?
Laboratory information management system: the laboratory's information about its samples, managed as one linked system. The free sheets on this site work the management arithmetic; the paid plan keeps the system.
What is LIMS used for in a laboratory?
Keeping every sample's chain from receipt to disposal as one record, showing the evidence behind every result, and working the figures the bench runs on: capacity, turnaround, cost, QC, storage, retention, calibration and review.
Is LIMS only for big laboratories?
No. The record and the arithmetic matter to a two-analyst bench as much as to a department; the size decides whether the system is an enterprise platform or a flat-price product like Limslane Pro, and the sheets work for either.
