Tribun Health

CaloPix is an image management platform with one AI application of Tribun's own. Case management, slide review, archiving and remote consultation all work without any model. Most of the AI it carries comes from other manufacturers through CaloPix Connect.

Tribun's own AI application is QC4AI, which its AI catalog lists as recognizing and quantifying visual defects in scanned slides. Tribun publishes nothing further about how it works.

Ask how QC4AI detects defects, whether it is a trained model, and which of the platform's AI functions Tribun builds itself.

Review by laboratory staff is implied, but no control is described. QC4AI flags and measures visual defects in scanned slides inside the platform, where laboratory staff and pathologists decide whether to rescan. AI applications from other makers show their results to the pathologist in CaloPix.

Nothing published states the defect level at which QC4AI flags a slide, whether a flagged slide is held back from AI analysis or diagnosis, or what happens when a defect is missed.

Ask how QC4AI's flags are acted on in the workflow, and whether the laboratory can set its thresholds.

Tribun describes its own AI by function only. QC4AI is said to detect and measure visual defects in scanned slides, and no model type, training data, version or update practice is published.

The outside applications in the catalog are named with their manufacturers. That tells a buyer who makes each model, but not how Tribun's own works.

Ask what kind of model QC4AI is, what it was trained on, and how updates are released and announced.

Tribun builds QC4AI itself and names the maker of every hosted model. The outside models on the platform are listed with their manufacturers, Mindpeak, Deep Bio, Owkin and Ibex, so a buyer can see who supplies each AI result.

What is not published is the hosting provider, whether partner applications run inside CaloPix or send images to the partner's own systems, and any subprocessor list.

Ask, for each AI application you would use, where images are processed and by whom, and for the hosting provider and subprocessor list for CaloPix.

Tribun shows scale and outside recognition for the platform, and nothing for its own AI. It reports more than 100 customers in Europe and North America, was named Best in KLAS for digital pathology in Europe from 2022 to 2024, and received FDA 510(k) clearance for CaloPix in May 2025.

Tribun's product and about pages name no customer site. No performance figure is published for QC4AI, such as how many defective slides it catches or misses.

Ask for QC4AI's detection and false alarm rates against manual quality control, and for reference laboratories running CaloPix in clinical use.

Tribun describes security controls, without answering the questions the AI raises. It describes database encryption, role based access, audit functions, password policies and a zero trust approach, and holds ISO/IEC 27001 certification.

Nothing published says how long slide images and case data are kept, whether customer slides train QC4AI or other models, or how any training data was de identified. No safety engineering for QC4AI is published.

Ask whether customer slides train any Tribun model, how long images and cases are kept, and how QC4AI errors are caught.

Tribun states no HIPAA position, and no privacy document covers the product. The legal notice of Tribun Health SAS, written under the GDPR and French law, covers the website and information sent by email. It names a data protection officer and says no personal data is transferred outside the EU.

It does not address patient slide images or case data held in CaloPix. Nothing published states a HIPAA position or offers a business associate or data processing agreement, although CaloPix is FDA cleared and sold in North America.

Ask for the data processing agreement and, for US laboratories, the business associate terms, and whether US customers' CaloPix data is hosted in the United States.

Tribun names a recognized certification, without publishing it. It states that it is certified to ISO/IEC 27001, dated 2025, and describes encryption, role based access control, audit functions and a zero trust approach.

The certificate, its scope and its issuing body are not published. There is no trust center, SOC 2 report or penetration testing statement.

Ask for the ISO/IEC 27001 certificate and statement of applicability, and whether its scope covers hosted CaloPix and archive services.

The platform is cleared, and nothing is stated about Tribun's own AI application. CaloPix received FDA 510(k) clearance on 14 May 2025 (K250414, product code QKQ for whole slide imaging systems). It is also CE marked under the IVDR and licensed by Health Canada, and Tribun notes that status varies by version and configuration.

Tribun's AI catalog says each application carries its own manufacturer, intended use and regulatory status. It lists QC4AI, Tribun's own, without a regulatory status or intended use statement. A platform clearance covers the image management and viewing functions, not an AI application running on them.

Ask for QC4AI's intended use and regulatory status in each market, and for the CaloPix version and configuration the 510(k) covers.

Tribun publishes nothing on how its own model is governed or tested. QC4AI carries no evaluation. Tribun describes no process for testing it across scanners, stains or laboratories, or for monitoring it after release. For the outside AI applications it hosts, it notes only that each has its own manufacturer and regulatory status.

Ask how QC4AI was evaluated and on which scanners and stains, and what review Tribun applies before adding an AI application to its catalog.

Staff can check QC4AI's flags, but nothing stands behind them. CaloPix has audit functions, and QC4AI's defect flags are shown to staff who decide whether to rescan, so an output can be checked and challenged.

No error rate, warranty, remedy or correction route for QC4AI is published. Responsibility for the outside applications sits with their manufacturers.

Ask what Tribun commits to when QC4AI misses a defect that affects a diagnosis or a later AI result.

Tribun offers interoperability as a service, without naming any system. CaloPix is itself the laboratory's image and case system. Tribun lists interoperability among its implementation services, and CaloPix Connect as the layer that brings AI applications in.

Its platform and services pages name no laboratory information system, record system, standard or production interface.

Ask which laboratory information systems CaloPix exchanges cases and results with in production, using which standards, and at which sites.

CaloPix is web based, and where it runs is implied, not stated. CaloPix Archive manages slide images across hot, cold and long term storage. Tribun's legal notice says it transfers no personal data outside the EU, but that statement covers website and email data.

Nothing published says where customer slide images are hosted, whether CaloPix can run on premises, or where North American customers' data rests.

Ask whether CaloPix runs on premises or hosted, the hosting provider and region, and where US and Canadian customers' images are stored.

No price is published, but what a laboratory buys can be worked out. Tribun sells CaloPix with archive, remote consultation and specimen imaging modules, and outside AI applications through its catalog. It also sells consulting, implementation, interoperability, training and maintenance services.

No license basis, per slide or per user price, or implementation fee is published.

Ask for the license basis for CaloPix and QC4AI, the cost of archive storage by volume, and how outside AI applications are priced through the platform.

Tribun names who CaloPix serves, with a clearance behind the platform. CaloPix serves hospital and private diagnostic laboratories, health systems, research centers, drug companies and contract research organizations, for whole slide review in routine diagnosis and research. Its May 2025 FDA clearance (K250414) and IVDR marking cover the platform within the scope each states.

QC4AI applies to H&E and other scanned slides for quality control, with no validation published.

Ask which scanners and uses CaloPix's clearance covers, and for any validation of QC4AI on your scanners and stains.
