Connecting the Siemens Atellica VTLi to your LIS or EHR

If you run point-of-care troponin on a Siemens Atellica VTLi, the result often still gets read off the screen and keyed into another system by hand. That takes time at the point of care, and every manual step is a chance to transpose a digit or attach a value to the wrong patient. On a numeric cardiac test, an accurate, well-attributed record matters.

Catenix removes that step. It captures results from the analyser automatically, keeps quality control runs apart from patient results, and forwards the finished result to the systems your site already uses. This page explains, in plain terms, what connecting an Atellica VTLi involves and what Catenix does with the data.

Quick answer

Yes, a Siemens Atellica VTLi can be connected so its results flow into your LIS or EHR without manual typing. The analyser speaks POCT1-A2 through its docking station over Ethernet, and a small Catenix gateway on site receives each result. Catenix captures the numeric troponin value and its unit exactly as reported, keeps quality control separate from patient results, and forwards the result onward with an audit trail. Catenix does not interpret the result.

What the Atellica VTLi measures

The Siemens Atellica VTLi is a point-of-care immunoassay analyser that reports a high-sensitivity cardiac troponin I (hs-cTnI) result from a small whole-blood sample. The result it produces is numeric: a quantitative value expressed in a unit of measure, rather than a graded category.

That numeric format matters for connectivity. A troponin figure and its unit need to travel through to the receiving system exactly as the analyser stated them, without rounding, reformatting or reinterpretation. Catenix is built to preserve the value and unit rather than change them. We make no claim about the device's clinical performance or its suitability for any diagnostic decision. Catenix does not interpret clinical results and provides no clinical decision support: it does not re-calculate the value, re-classify it, derive an estimate from it, or flag it against any threshold. Interpretation, validation and authorisation stay with your clinicians.

How it connects

The Atellica VTLi connects through its docking station, and over that connection it offers a network interface built on POCT1-A2, a connectivity standard designed for point-of-care devices. In general terms, POCT1-A2 describes how a small analyser and a data manager communicate over a network, covering how the device is discovered, how results are passed across, and how the exchange is acknowledged. Because the docked analyser communicates over Ethernet rather than a serial cable, it does not need to sit next to a dedicated PC.

On your site, Catenix runs a small gateway. The gateway sits on the same network as the docking station and acts as the data manager the device connects to. It receives each result as it is produced, then passes it securely to your Catenix cloud workspace. The gateway is the only new hardware a connection needs, and it is deliberately lightweight, so it can run on modest hardware in a clinic or practice without a lot of setup.

Results and quality control in Catenix

When a result arrives, Catenix records it against the patient and keeps the numeric value and unit as reported. Nothing is retyped, so the figure your operator saw on the analyser is the figure that lands in the workspace, timestamped and attributed with an audit trail showing when it was captured and by which device.

Quality control runs are handled differently from patient tests. Catenix identifies QC material and keeps those runs in a separate stream, so control results never mix into a patient record and your QC history stays intact for review. This separation is one of the reasons sites choose to connect an analyser rather than log results by hand, where QC and patient entries can end up in the same place.

Once a patient result is captured, Catenix can forward it to the systems your site already runs, such as a laboratory information system or an electronic health record. Each result carries an audit trail showing when it was captured and where it was sent, which supports your record keeping without extra effort.

Getting connected

To connect an Atellica VTLi you need the analyser docked on your network, a Catenix gateway on the same network, and details of the LIS or EHR endpoint you want results delivered to. Most sites get going without changes to the analyser itself, since it already speaks POCT1-A2.

Questions clinics ask

Can I connect a Siemens Atellica VTLi to my LIS?

Yes. The analyser offers a POCT1-A2 network interface through its docking station, so a Catenix gateway on your site can receive each result and forward it to your LIS or EHR. Results flow through without manual typing, and quality control runs are kept separate from patient records.

Does it connect over the network or a serial cable?

Over the network. The Atellica VTLi connects through its docking station over Ethernet and speaks POCT1-A2, so the analyser communicates over your ordinary network rather than a serial connection.

How does the numeric troponin result come through?

The high-sensitivity troponin result is a numeric value with its unit of measure. Catenix captures the value and unit exactly as the analyser reports them, so the figure your operator saw is the figure that lands in the workspace. Catenix does not re-calculate or re-classify the value.

What happens to quality control results?

Catenix identifies QC runs and keeps them in a separate stream from patient results. Control results do not enter patient records, and your QC history is retained so it can be reviewed later.

Do we need to change anything on the analyser?

In most cases, no. The analyser already speaks POCT1-A2 through its docking station, so a typical connection needs the docked device on your network, a Catenix gateway on the same network, and the details of the LIS or EHR you want results sent to.

Can Catenix send results to more than one system?

Catenix captures the result once and can forward it onward to the systems your site runs, such as a laboratory information system or an electronic health record. If you need results delivered to a particular endpoint, our team can confirm what is supported for your setup.
