Connecting a Werfen GEM Premier to your LIS or EHR

If your clinic runs a Werfen GEM Premier for blood gas testing, chances are results are still read off the analyser screen and typed into the record by hand. During busy periods that takes time, and every manual step is a chance for a transcription slip or a result that never reaches the right place.

Catenix removes that step. It captures each result from the analyser automatically, keeps quality-control runs out of the patient record, and passes finished results on to the system your site already uses. This page explains, in plain terms, what connecting a GEM Premier involves and what Catenix does with the connection.

Quick answer

The Werfen GEM Premier 4000 and 5000 offer an HL7 result interface over the network. Catenix connects to that interface through a small on-site gateway, captures each result automatically, keeps quality-control runs separate from patient results, and forwards finished results to your LIS or EHR. There is no manual transcription, and the audit trail is kept.

What the GEM Premier measures

The Werfen GEM Premier 4000 and 5000 are blood gas analysers used in urgent and critical care settings. They run blood gas and related measurements at the point of care, so a result is available quickly without sending a sample away to a central laboratory.

Catenix does not change how the analyser runs a sample or what a result means. Our role begins once the analyser has produced a result: we are concerned with connectivity and with how the data is handled after it leaves the device. Nothing on this page is clinical guidance, and Catenix makes no claim about the analyser's measurements or their suitability for any clinical decision.

How it connects

Both models offer an HL7 result interface over the network. HL7 version 2 is a long-established healthcare messaging standard: the analyser sends a structured electronic message describing a result, and a receiving system reads that message and files the result. Sending it over the network means the two systems exchange data across the site's local network rather than through a cable running directly between two machines.

Catenix connects to that interface using a small piece of software we call the on-site gateway. The gateway sits on the site's network, listens for results from the GEM Premier, and passes them securely up to your Catenix workspace in the cloud. It is deliberately light: it does not need its own server room, and it is designed to keep working quietly in the background once configured. The messaging detail is handled between the analyser and the gateway, so your team does not need to learn anything about the underlying format.

Results and quality control in Catenix

When a result arrives, Catenix records it with the details needed for a proper audit trail, including when it was captured and which device it came from. Because the result is captured electronically, nobody has to read it off a screen and retype it into another system, which is where transcription errors usually creep in.

Quality-control runs are handled differently from patient samples. Catenix recognises QC material and keeps those runs separate from patient results, so your QC record stays together and your patient record is not cluttered with control data. That separation helps when you review analyser performance over time and when you need to show that controls are being run. Once a patient result is captured, Catenix can forward it onward to the system your site relies on, whether that is a laboratory information system (LIS) or an electronic health record (EHR), in the format that system expects to receive.

Getting connected

To connect a GEM Premier, a site needs the analyser reachable on its local network, the on-site gateway installed, and agreement on where finished results should be delivered. Most of the setup is configuration rather than new hardware, and Catenix handles the connectivity detail so your team can stay focused on testing.

If you are weighing up whether this fits your site, the best next step is a short conversation about your analyser, your network, and the system you want results to land in.

Questions clinics ask

Can I connect a Werfen GEM Premier to my LIS?

Yes. The GEM Premier 4000 and 5000 offer an HL7 result interface over the network, and Catenix captures results from that interface and forwards them to your LIS or EHR. The result arrives in the format your system expects, so it files correctly without manual retyping.

Do I need a new server or a lot of hardware on site?

No. Catenix uses a small on-site gateway that runs on the local network and passes results up to your cloud workspace. It does not need a dedicated server room, and most of the work is configuration rather than new equipment.

What happens to quality-control runs?

Catenix recognises QC material and keeps those runs separate from patient results. Your quality-control record stays together for review, and patient records are not mixed with control data.

Will connecting change how the analyser works?

No. Catenix reads results after the analyser has produced them. It does not alter how the device runs a sample or what its results mean, and it makes no clinical claims about them.

Which systems can Catenix forward results to?

Catenix can forward captured results to a laboratory information system or an electronic health record, in the format that system expects. If you are not sure what your site uses, we can talk it through via the contact page.

Is the connection secure?

The gateway passes results from the site up to your Catenix workspace over a secured connection, and every result is recorded with an audit trail. You can read more about how we handle data on the security and trust pages.
