Sending GEM Premier 5000 results to your EHR or LIS
Quick answer
Yes. The GEM Premier 5000 offers ASTM or HL7 as its interface protocols for passing data to a laboratory or hospital information system. A Catenix gateway on your network takes in that feed and forwards every panel to the EHR or LIS under the correct patient. The protocol in use and the network details are confirmed on your unit during setup.
Where the GEM Premier 3500 menu ends at gases, electrolytes, glucose, lactate and haematocrit, the GEM Premier 5000 adds full CO-oximetry and an optional total bilirubin to the same cartridge. One 150 microlitre sample of heparinised whole blood gives pH, pCO2, pO2, sodium, potassium, ionised calcium, chloride, glucose, lactate, haematocrit, total haemoglobin and the haemoglobin fractions, 45 seconds after the sample goes in.
Werfen places it in laboratories, intensive care, theatres, cath labs and emergency departments. It works through about 29 samples an hour, and a micro mode takes 65 microlitres from a capillary when CO-oximetry is not needed.
| What | How Catenix handles it |
|---|---|
| What it measures | Blood gases, electrolytes, glucose, lactate, Hct, CO-oximetry, optional tBili |
| Blood needed | 150 uL full menu; 100 uL CO-ox and tBili only; 65 uL capillary micro mode |
| Speed | 45 seconds per sample, about 29 samples an hour |
| Interface protocols | ASTM or HL7 |
| GEM PAK | 75 to 600 tests, 31 days on board (21 for the 600-test PAK) |
| Built-in quality checks | iQM2 with IntraSpect |
| Maker's data manager | GEMweb Plus 500 |
A longer result message than the GEM 3500 sends
A full GEM Premier 5000 panel carries more than fifteen measured values, and the PAK fitted decides which of them appear: Werfen lists over 30 menu options, with or without bilirubin. During setup each analyte code the analyser sends is mapped to the matching code in your EHR, so oxyhaemoglobin, carboxyhaemoglobin and methaemoglobin land in their own fields instead of a free-text note.
Catenix stores the original ASTM or HL7 message beside the result it produced. If a clinician later asks where a lactate came from, the answer is one click away.
iQM2 runs inside the analyser, Catenix sits outside it
iQM2 builds quality checking into the analyser itself, with five kinds of check: system checks, sensor checks against process control solutions, pattern recognition, IntraSpect checks during every sample, and stability checks on the solutions themselves. Faults are detected, corrected and documented by the analyser.
That record stays with the GEM Premier 5000 and GEMweb Plus. Any control material your site still runs and transmits is filed by Catenix as QC, graded against Westgard rules and drawn on a Levey-Jennings chart, and a failed control holds patient results for that test.
Network notes for theatres and intensive care
Werfen highlights integrated Wi-Fi on the GEM Premier 5000; the wired port options are confirmed on your unit during setup. The gateway reconnects by itself after a network drop and keeps results on site through an internet outage, releasing them to the EHR once the line returns. A panel that arrives with a patient ID the EHR does not recognise waits for review.

Questions people ask
Is the GEM Premier 5000 interface ASTM or HL7?
Either. The analyser's published interface protocols are ASTM or HL7, and the one used at your site is agreed during setup.
How is the GEM Premier 5000 different from the GEM Premier 3500 for connection purposes?
It reports more: full CO-oximetry and optional total bilirubin as well as gases, electrolytes, glucose and lactate. More codes need mapping to the EHR, which is done once during setup.
Do we need GEMweb Plus 500 to use Catenix?
No. GEMweb Plus 500 manages analysers and operators. Catenix handles the route from the analyser's ASTM or HL7 output into your EHR or LIS.
