Laboratory software for a Windows computer

Clarus LIS is medical laboratory software that runs on your laboratory's own computer with no internet, on a perpetual licence you can move to a new computer if you replace yours, and it brings in the data from your previous program (Access or SQL Server).

A 14-day free trial with every feature, then a perpetual licence at the published price, and continuous updates free of charge.

Our team's experience: 878 laboratories worked with our earlier programs over seven years.

The report is what the doctor and the patient see first

Reports that carry your laboratory's identity, with no pre-printed paper

The program prints the whole report itself, with your laboratory's logo, name, contact details and address in the header, so no pre-printed paper is needed. A laboratory administrator can change the report title, logo, colours, layout and identity details at any time.

  • Three signature places at the end of every report: the lab technician, the clinical pathologist and an authorised signatory. The laboratory sets each name, title and uploaded signature, or leaves a blank line to sign by hand.
  • The report prints on the laboratory's printer, or downloads as a PDF file.
  • On single-test reports and on chemistry, drug-monitoring and allergy panels, the report can show a colour-coded Low / Normal / High bar with a marker where the first flagged numeric result falls in its reference interval.
  • When a patient has earlier results for the same test, the report can list them with their dates and, on a single-test report, draw a trend chart of up to ten previous values.
  • A QR code opens the laboratory's current copy of the report so a printed copy can be checked, whenever your laboratory has an address a patient's phone can reach.

Before you decide

Short answers to what laboratory owners ask first

Is the program free?

No, but it has a 14-day free trial with every feature: the same edition you buy, with no limit on user accounts. When the trial ends, the program stops until you activate a perpetual licence at the published price; your data stays on your computer untouched, and you can export a complete copy at any time. Moving the licence and the laboratory website need an activated copy.

Download the trial

Does it print my report on my laboratory's letterhead, and as a PDF?

Yes. Your laboratory's logo, name and details head every report, three signature places close it, and the report prints directly or downloads as a PDF file.

Report samples

Will it run on my laboratory's computer once installed?

It runs on a Windows 10 or 11 (64-bit) computer, and its database is installed with it by the same installer, so there is no other program to install. Daily work needs no internet; the internet is only for optional services such as online activation (activation by phone works instead), updates, the laboratory website and WhatsApp messages.

Download and system requirements

How much is it, and is there service after the sale?

One published price for a perpetual licence for your computer, with no setup fees and no hidden fees. Updates are included for life: the program checks for them automatically, and you download and install one in two clicks, with a rollback copy.

Who teaches me the program, and how do I reach you?

Can I add my own tests and edit reference ranges?

Yes. A user with the administrator or manager role adds tests and edits their reference ranges from the catalogue screen, and can import a list of tests and prices from a CSV file. The program starts with a catalogue of 1,300 tests, 202 of which are enabled at installation; the laboratory enables whichever of the rest it wants.

Will I lose my data if the computer fails?

The program takes a backup automatically every day, checks each backup after taking it, and can copy it automatically to a second drive the laboratory names, such as a USB drive. You can also rehearse a real restore of the latest backup from inside the program, into a temporary database that never touches your live data.

What sets Clarus LIS apart

What you get with laboratory software on your own computer

Every line here describes what the program does today.

Move your laboratory from your previous program (Access or SQL Server), with its data and test names

A wizard inside the program reads the database files directly (Access .mdb or SQL Server) with neither of them installed, brings across patients, visits, results and your test catalogue with its names, reference ranges and packages, and shows the counts before it writes anything. The wizard reads one specific program's database; if yours is a different program, our team moves your data with you from CSV or Excel files.

A perpetual licence for your computer that moves with you if you replace it

A perpetual licence for this computer that never expires, and no monthly subscription. If you replace the computer, you press "Move this licence to another computer" in the program, read us the code it shows, and we release your same serial for the new computer.

It works with no internet, and your data stays on your laboratory's computer

All daily work runs on the laboratory's computer with no internet connection, and patient data is kept in a database on that same computer. The internet is used only for optional services, such as online activation (a phone works instead), updates, the laboratory website, and WhatsApp, SMS and email messages.

Analyzer connection included in the licence, and a laboratory website free for the first year

Analyzer connection is included, with no fee per device and no limit on their number: over the serial port (ASTM and HL7) and over the network (HL7 and text). An activated licence also includes a website for your laboratory, free for its first year, at an address you choose on claruslis.com, where a patient reads their report through a QR code, end-to-end encrypted.

Reports that carry your laboratory's identity, with no pre-printed paper

Your laboratory's logo, name and address head every report, three signature places close it, and the administrator changes the design at any time.

A 14-day free trial with every feature, before you pay

The trial is the same edition you buy, with no limit on user accounts. After it ends, the program stops until you activate the licence; your data stays on your computer, and you can export it at any time.

One published price

A published price shown for your country, with no setup fees and no hidden fees, and updates included for life.

Clarus LIS Manager: your laboratory and its branches on your phone

Clarus LIS Manager is a free Android app for the laboratory's manager and whoever the manager allows: follow your laboratory, receive its alerts and decide from anywhere. It works with the trial too.

  • Each branch's figures today: orders, results released, and those released on time.
  • The program's alerts with no Google services: a critical result, a rejected sample, a backup that did not complete.
  • Approve results, decide discounts and refunds, and message the program's screens, with your permissions.
  • It pairs with your phone through a code shown only inside the laboratory, and opens with your fingerprint or your phone's lock.
