A LIMS laboratory looks, from the outside, exactly like one without a LIMS: the same samples arrive, the same instruments run, the same reports go out. The difference is inside the day. Without a system, booking in is a line in a register, the batch sheet is a printout, the freezer position is a label somebody remembers, the reviewer's initials are in a margin, and the question of whether next week fits on the bench is answered by feel. With one, every one of those is a field on a record that knows the others, and the question about next week is a number. This page walks a day on the bench both ways and shows where the free sheets on this site put the numbers into the day before any system is bought.
Morning: booking in and the week's load
Samples arrive with a chain of custody form and are booked in with their tests. In a register that is the end of it; in a LIMS the booking creates the tests, assigns the batch and updates the week's load. The intake sheet on this site works that load from five figures: samples, tests per sample, minutes per test, analysts and bench hours, returning the hours the week needs, the capacity, the utilisation and the turnaround. A lab that works that sheet on Monday morning knows by nine o'clock whether Friday's promises hold.
Midday: the batch, the controls and the instrument
The batch runs with its blanks, duplicates and reference materials, on an instrument whose last calibration is on a sticker or in a record, with a reagent lot whose expiry is on the bottle or in a record. The system keeps all three against the batch; the quality control sheet and the instrument calibration sheet on this site work what the scheme and the schedule cost. Neither sheet decides the scheme or the interval, which are the method's and the accreditation body's; both show what the decision costs.
Afternoon: review, report, store
Results are reviewed by someone other than the analyst, reported to the client, and the sample goes to a freezer position with a retention date. The results review sheet works the reviewer hours; the storage and retention sheets work the freezer months, the boxes and the month's disposals. The guide this page supports takes the day and turns it into the four questions that choose a system. Limslane Pro keeps the day's record for a small lab at one flat price; the sheets stay free.
Questions people ask about lims laboratory
What does LIMS stand for in a laboratory?
Laboratory information management system: the linked record of samples, tests, batches, results, reagent lots, instruments and storage, and the arithmetic that record allows. The free sheets on this site work the arithmetic; the paid plan keeps the record.
What changes on the bench with a LIMS?
The questions that were answered by feel become numbers: whether the week fits on the bench, what a test costs, how much of the bench QC takes, when the freezers fill, what leaves retention, what calibration costs. The seven sheets here work each of those without a system.
Do I need a LIMS to use the sheets?
No. Every sheet computes on the page from the lab's own figures with no account. Limslane Pro keeps the record the sheets produce; an enterprise LIMS keeps it with interfaces a small lab may never need.
