Connecting the Cepheid GeneXpert to your LIS or EHR

Molecular testing at the point of care puts a real-time PCR result in reach of the clinic, but the result still has to arrive in the systems your clinic runs on. Where that last step is manual, someone reads a detected or not-detected result, or a quantitative value, off the screen or a printout and keys it into the patient record. That takes time, it is easy to transpose a digit or mislabel a target, and the record of who did what can be thin.

This page explains, in plain terms, how a Cepheid GeneXpert can send its results into a laboratory information system (LIS) or electronic health record (EHR), and what Catenix does in the middle so that results flow automatically and quality-control data stays where it belongs.

Quick answer

The Cepheid GeneXpert reaches the network through its Xpertise software, which offers an HL7 v2 result interface, with ASTM also supported. Catenix captures those results at your site with a small on-site gateway, keeps quality-control runs separate from patient results, preserves an audit trail, and can forward the patient results to your LIS or EHR. You avoid manual transcription and keep a clear record of what was received.

What the Cepheid GeneXpert measures

The Cepheid GeneXpert is a cartridge-based real-time PCR molecular system. A single-use cartridge is loaded for each test, sample preparation and amplification run inside it, and the assay reports either a qualitative result (for example, a target detected or not detected) or a quantitative value, depending on the cartridge in use. The menu available depends on which Xpert cartridges your site runs.

Catenix does not change what the device measures or how it is operated. Our scope is connectivity: taking the results the system already produces and moving them reliably into your other systems. We make no claim about the device's clinical performance or its suitability for any diagnostic decision.

How the GeneXpert connects

The GeneXpert instrument is driven by its Xpertise software, and it is that software that presents results to the wider network. On its public data sheets, Xpertise offers an HL7 v2 result interface, with ASTM also supported, the same general messaging families used across much of healthcare for sending results between systems. The connection is bidirectional, so as well as returning results the software can accept orders and worklist information where your configuration allows it.

HL7 version 2 is a long-established standard for exchanging clinical messages such as results, and ASTM is a comparable standard commonly seen on laboratory instruments. In broad terms, each message carries the identifying details of a test event and the values that go with it, structured so that a receiving system can file them against the right record. Catenix speaks these general interfaces. We do not need, and this page does not publish, any vendor-specific internal detail about how individual values are laid out.

At your site, a small Catenix gateway sits on the local network and receives the result messages the Xpertise software sends. The gateway is the only piece of new hardware involved, and it runs quietly alongside your existing kit.

Results and quality control in Catenix

Once the gateway receives a result, Catenix records it in your cloud workspace with a timestamp and keeps an audit trail of what arrived and when. Nothing is retyped, so the value in the record is the value the system produced, whether that is a qualitative detected result or a quantitative figure.

Molecular systems also produce quality-control and control runs, the checks that confirm the instrument and cartridges are behaving as expected. Catenix identifies these QC runs and keeps them separate from patient results, so a control sample never lands in a patient's record and your QC history stays intact for review. This separation is worked out from the information in the incoming results, without any change to how the system is used.

From there, Catenix can forward the patient results onward to the systems your site already runs, such as a LIS or an EHR. The result flows once, automatically, from the instrument through to the record, and the same audit trail follows it.

Getting connected

To connect a GeneXpert, a site typically needs the Xpertise software configured to send results over the network, a Catenix gateway on that same network, and agreement on where patient results should be delivered. Most of the setup is configuration rather than new equipment.

If you are planning a connection or want to check what your current setup allows, our team can talk it through with you. See /contact/ to get in touch, /platform/ for how the workspace and gateway fit together, and /pricing/ for how it is packaged. For security and data handling, see /security/ and /trust/.

Questions clinics ask

Can I connect a Cepheid GeneXpert to my LIS?

Yes. The GeneXpert's Xpertise software offers an HL7 v2 result interface over the network, with ASTM also supported, and Catenix captures results from it and can forward them to a LIS or EHR. The main requirement is that the software is set to send results and that a Catenix gateway is on the same network.

Do I need new hardware to make this work?

The only new item is the small Catenix gateway that sits on your local network. Your GeneXpert instrument and its Xpertise software carry on as they are, and most of the work is configuration rather than installation.

How are quality-control runs handled?

Catenix recognises QC and control runs in the incoming results and keeps them separate from patient records. Your control results stay grouped for review and never appear against a patient, which keeps both the patient record and the QC history clean.

Will results still be transcribed by hand?

No. Once the connection is live, results move from the Xpertise software into Catenix and onward automatically, so nobody rekeys a value. An audit trail records what was received and when.

Which assays or cartridges are supported?

Catenix carries whatever result the Xpertise software sends, whether the assay reports a qualitative detected result or a quantitative value, so the tests available depend on the cartridges your site runs rather than on Catenix. We handle the connectivity, not the measurement itself.
