Connecting a Beckman Coulter AU5800 to your LIS or EHR
Quick answer
Yes. The AU5800 series is documented with a bidirectional LIS interface offering both broadcast download and host query. Catenix can push the EHR's orders ahead of the racks or answer the analyser's query for each barcoded tube, then return matched results. The physical link and message settings are read from your AU5800's host configuration during setup.
The AU5800 is Beckman Coulter's highest-volume chemistry line, built from one to four analytical modules. A single-module AU5810 runs up to 2,000 photometric tests an hour and the four-module AU5840 up to 8,000, rising to 9,800 with dual ISE. Beckman Coulter sizes the AU5810 for hospital and reference labs doing 1.0 to 2.5 million tests a year, and the AU5840 for reference labs above 6.5 million.
Every configuration takes 400 samples in racks, with STAT priority and automatic repeat of abnormal results. Onboard reagents scale from 54 on one module to 216 on four. For a private lab this sits at the far end of the range from a benchtop analyser, and the host connection has to keep pace with it.

Download or query at core-lab volume
At this volume nobody picks tests at the console. Using broadcast download, Catenix sends the EHR's orders before the racks are loaded; using host query, the AU5800 reads each barcode and asks, and Catenix replies with that tube's tests. The analyser's sample management then schedules racks according to the tests ordered.
Tube labels must be in a symbology it reads: Interleaved 2 of 5, Codabar, Code 39 or Code 128, which the reader tells apart automatically.
Repeats, dilutions and a long audit trail
The AU5800 repeats abnormal results automatically, reruns high results after dilution and low results after concentration. Catenix stores the message behind every result, so on a day with many thousands of tests a repeated value can still be traced to what the analyser sent. Test codes for each module, ISE included, are mapped to EHR codes during setup, and results that match no order wait for review.
Beside automation and other lab IT
Beckman Coulter says the AU5800 can be combined with pre-analytical automation, immunoassay systems and clinical IT, and offers its own Remisol Advance middleware. Where Catenix is the host, its on-site gateway reconnects after network drops and holds results in the lab through an internet outage. Controls it receives are filed as QC, graded with Westgard rules and charted on Levey-Jennings plots, and a failed control holds patient results for that test.

Questions people ask
Can an AU5800 ask the host for orders?
Yes. Host query is documented for the series alongside broadcast download, so Catenix supplies the EHR's tests for each tube either way.
Is the connection different for an AU5810 and an AU5840?
The models differ in module count, throughput and onboard reagents. Host settings are confirmed on your own configuration during setup.
Which barcode labels can the AU5800 read?
Interleaved 2 of 5, Codabar, Code 39 and Code 128, with automatic discrimination between them.
