Comparison

Excel for a clinical lab: how far it holds up

Most small laboratories in Mexico run on a spreadsheet, a notebook and WhatsApp. That is not stupidity: it works, it is already paid for, and nobody had to be trained on it. Here is the honest comparison, including where Excel is still the right answer.

Point by point

Comparison between running on Excel and a notebook and running on Itzli
What you doOn Excel and a notebookOn Itzli
Get the result off the analyzer You read it on the instrument’s screen and type it in. A digit typed wrong is a digit nobody catches. It arrives from the instrument on its own, matched to the order by folio (the order number) — if it is one of the three supported models.
Know who validated a result You remember, or you ask whoever was on shift that day. The signer’s name and professional license number, stored exactly as they stood that day, on every report.
Balance the cash drawer You add it up at close and hope it comes out. Whatever does not match, you hunt for by hand. Cash-drawer close by branch and by employee, counted separately by payment method, and a blind close.
Find a result from three months ago You dig through folders, the WhatsApp thread, or the filing cabinet. You search the folio and it is there, with its PDF and its history.
Know which reagent is about to run out You find out once it has already run out. Coverage measured against your real working pace, with expiry warnings and cost per test.
Reprint a receipt If you did not keep a copy, you make it again. A receipt history you can reprint, on a thermal ticket or on a full letter-size sheet.
Correct a result you already handed over You fix the file and what it used to say is gone. The history stays: what it said, what it says now, who changed it and why.
Get new patients through the door Word of mouth, and whoever walks past. The same, plus the comparison tool — if you decide to publish prices. Do not expect miracles: it is the youngest part of the product.
Cost of the software Zero, plus the hours that go into retyping. From MXN $990 a month, with migration included.
Work without internet Excel opens either way. You need a connection. The bridge does survive outages: it queues to disk and uploads when the line comes back.

When to stay on Excel

Those cases are real and there is no point pretending otherwise.

  • If you run very few tests a month, the monthly fee will cost you more than it saves you.
  • If you work alone, with nobody else entering results, knowing who did what buys you very little.
  • If your internet is genuinely bad and there is no plan B, a system in the cloud will get in your way.
  • If you are about to close or sell the laboratory, this is not the moment to change systems.

When Excel has started costing you

These are the signs laboratories have described to us.

  • More than one person is entering results and the versions of the file fight each other.
  • A result went out with a mistyped value and somebody had to go correct it.
  • You closed the month without really knowing what you made.
  • You opened a second branch, or you are about to.
  • You bought a new analyzer and somebody is typing in what the instrument already calculated.
And about the other lab systems: there are several in Mexico and not all of them are bad. What makes Itzli different is not a longer list of modules — it is that it reads your analyzers from the entry plan, and that the catalog you operate on can bring you patients. If a competitor solves that better for you, buy it from them.

Compare it against your own month

Bring your spreadsheet to the demo. We load your catalog, enter one real day of work, and you compare: how long it used to take you and how long it takes now.

  • We migrate your catalog, at no cost
  • 30-day trial on your real operation
  • If your cash drawer does not balance in 60 days, you do not pay

No commitment. Your data is handled under Mexico’s federal data protection law (LFPDPPP).
