Connecting a Mindray BS-200 to your LIS or EHR
Quick answer
Yes. Mindray lists a bi-directional LIS interface for the BS-200, tied to its optional internal barcode reader. Catenix takes the host role, collects results from the BS-200 workstation and passes them to your EHR or LIS. Mindray's published specifications do not name the message format, so protocol and port are confirmed on your unit during setup.
The BS-200 is the long-serving small model in Mindray's BS chemistry range: a discrete, random-access analyser rated at 200 photometric tests an hour, or up to 330 with the optional ISE module for potassium, sodium and chloride. It stands on a bench 860 mm wide, or on an optional cabinet, and is driven from a separate Windows PC.
One refrigerated tray carries 40 reagent positions and 40 sample positions, with no fixed places for patients, controls, calibrators or STAT samples. Reactions run in disposable cuvettes, the clearest hardware difference from the newer BS-240 with its washed, reusable ones. Mindray describes the BS-200 as an open system with user-defined profiles and calculated chemistries.

Is the barcode option fitted to your BS-200?
The internal barcode reader is an extra on this model, not standard. Where fitted, it scans sample and reagent labels printed in Codabar, Interleaved 2 of 5, Code 128, Code 39, UPC/EAN or Code 93. On a unit without one, sample details are entered by hand at the workstation, so the ID typed there has to agree with the ID on the EHR order.
Catenix pairs every incoming result with its order using that sample ID. A result whose ID fits nothing is parked for a person to look at instead of being filed on a guess.
A PC-driven analyser on a small lab network
Because the BS-200 is operated from Windows software on its own PC, the link to a host starts there. Mindray lists RS-232 as the operation unit's interface; which connection your software version uses for the LIS is among the first things checked during setup. If it proves to be a serial port, a serial device server places it on the network for the gateway.
The gateway runs inside the lab. Should the network blip, it reconnects without anyone restarting it, and if the internet link fails, results stay on site until they can be forwarded. BS-200 test names are mapped to the codes your EHR uses, and each message is stored beside the result it produced.
Controls on the BS-200 and in Catenix
The BS-200 software applies Westgard multi-rule checks, a cumulative sum check and twin plots to its own control runs. Any controls transmitted to the host are filed by Catenix as QC and kept out of patient records, graded against your lab's targets with Westgard rules and drawn on Levey-Jennings charts. A control failure puts patient results for that test on hold.

Questions people ask
Is the Mindray BS-200 bi-directional?
Mindray lists a bi-directional LIS interface. How orders reach your unit is confirmed during setup; if it runs results-only, Catenix matches results to EHR orders by sample ID.
Does every BS-200 have a barcode reader?
No. The internal reader for sample and reagent barcodes is an option, so check whether yours has it before planning the workflow.
Does the ISE module change the setup?
It adds potassium, sodium and chloride and lifts throughput to as much as 330 tests an hour. Those three tests are mapped to EHR codes like the rest.
