UK-built POCT middleware
Catenix connects your point-of-care analysers to the clinical system your team already uses, whether that is EMIS Web, SystmOne, a LIMS or an EPR, and files each result against the right patient. Quality control, operator competency and the audit trail build as you work, so the evidence exists before anyone asks for it.
For POCT coordinators, quality managers, clinic teams and the IT people who support them. One site or a whole network: hospital, community, private clinic, mobile or remote.
How it works
Catenix reads your device over its own protocol, normalises the result and delivers it to the patient record in seconds. No re-typing, no USB sticks, no waiting.
Where it breaks
Pick the one that sounds like yours. The path shows where the flow breaks, what Catenix does about it, and where to read more.
> trace patient → invoice 6 nodes break at patient → analyseranalyser → recordrecord → qualityquality → reportreport → invoice
Someone reads an ID off one screen and types it into the analyser. One transposed digit and the result belongs to somebody else, which you may only find out later.
What Catenix does. The worklist goes out to the analyser with the patient already attached, and the result comes back matched to that same record. Nobody types an ID twice.
Bidirectional connectivity, not just result captureResults sit on the analyser, in vendor software, in a binder or on a USB stick. Someone re-keys them into the record, then the report, then the invoice. Every copy is a chance to get it wrong.
What Catenix does. A small on-site gateway reads the analyser directly, so the result is in the patient record seconds after the run finishes, with quality control kept separate from patient results automatically.
HL7, POCT1-A2 and ASTM, plus RESTCharts get drawn after the fact, competency sits in a folder, and audit week means reconstructing evidence you already had. The work was done properly. Proving it is the expensive part.
What Catenix does. QC runs are captured as they happen, Westgard rules flag the failures, and competency is recorded against the person who ran the test, so the evidence assembles itself as you work.
Levey-Jennings and a tamper-evident audit trailA result produced in minutes takes days to reach the person it belongs to, because someone has to assemble the report, check it and send it on.
What Catenix does. Branded reports build from the same record the test landed in and go out by the route each patient or corporate client expects, once a clinician has authorised them.
Report and deliver from one recordTests get run and never billed, or billed twice, because the invoice is built from a different list than the work. Reconciling the two is somebody's whole afternoon.
What Catenix does. Invoices are raised from the same encounter as the test, so what you bill is what you actually ran, whether the payer is the patient, an insurer or a corporate account.

Works with your stack
Your analysers on one side, your record system on the other. Catenix sits in between and speaks to both.
UK and US clinical systems, GP systems, LIMS and EPRs, plus 46 analyser connection guides over HL7, POCT1-A2, ASTM and FHIR. See all integrations →
What Catenix does
Everything below reads from and writes to the same record, so the evidence for an inspection is a by-product of running the service, not a project before the visit.
Every analyser reads into one record through a small on-site gateway, with the worklist going out to the device. Standards in, standards out.
Connectivity →No silent overwrites: reassign with a reason, audit on both patients, downstream corrections, critical results acknowledged before release, amendments that keep the original.
Results governance →QC captured from the analyser, Westgard rules and Levey-Jennings per device and analyte, lockouts, material expiry, failure reviews and the monthly sign-off.
Quality control →Verify a new analyser with EP15 and EP09 style studies, linearity, detection limits, reference intervals, measurement uncertainty and sigma, in a signed pack.
Workbench →Non-conformances, incidents, CAPA, ISO 15189:2022 audit checklists, a 5x5 risk register, field safety notices and a management-review pack that fills itself.
Quality management →Service, cleaning, downtime, custody, temperature excursions, firmware and opened reagents per device, with overdue items escalating on their own.
Device operations →Individual identity at the device, certification per operator per method with expiry, reminders before it lapses, competency in the management review.
Operators →Deadlines with staged reminders and a calendar file, structured investigations of failed returns, z-score trends and an annual summary.
EQA →Which lots were on which analyser when each result was produced, recall impact lists you can export, and cost per test.
Traceability →Rules decide who hears about what; one acknowledgement stops the chain; escalation climbs when nobody answers; the Action Centre lists today's work.
Notifications →Arrange your own dashboard from 46 widgets with presets for each role, and ask the questions standard reports miss.
Dashboards →Hash-chained, verified per organisation, with the history of any record one click away and extracts that carry a cover sheet.
Audit trail →Registration, appointments, encounters, the patient record, duplicate merge with an undo, identity confirmation at the moments that matter.
Patient management →Branded reports and GP letters from the same record, released once authorised, with results in the patient's pocket.
Reporting →Invoices off the same encounter as the test, and stock by lot and expiry per site and device.
Billing →A read-only assistant that finds features, explains the platform and looks up your own operational data. Never the diagnosis.
Analytics & AI →Works with your bench
Chemistry, immunoassay, blood gas, haematology, molecular and urinalysis, connected through a small on-site gateway. Quality control is kept separate from patient results automatically, and results push on to your LIMS, EPR, GP system or EHR.

Questions, answered
Catenix is point-of-care testing software: POCT middleware that connects analysers to one record, plus the quality control, competency, quality management, results governance, reporting and billing a testing service needs. It runs a single site or a whole network.
Both, depending on how you use it. Hospital and laboratory teams use it as connectivity and QC middleware that forwards results to a LIS. Clinics use it as the working record from booking to report to invoice. Same platform, modules switched on per site.
HL7 v2, POCT1-A2 and ASTM at the device, with FHIR and REST for clinical systems. Connectivity is bidirectional, so the worklist can go out to the analyser with the patient already attached.
The worklist goes to the analyser with the patient attached and the result matches back to that record, so an ID is never typed twice. Where a manual match is needed it is a recorded decision: moving a result needs a coded reason, is audited on both patients, and downstream systems receive a correction. See results governance.
One subscription per site covering the core modules, device drivers, updates and support, with optional add-ons at a flat monthly price. There are no per-test fees. See how pricing works.
