Medica EasyLyte LIS & EHR Connection

Quick answer

Yes. Every current EasyLyte model has an RS-232 serial port that outputs results to a computer. Catenix reads that port through a small serial device server and sends each electrolyte result to your EHR or LIS. The output format and the cable are confirmed on your unit during setup.

The Medica EasyLyte is a small ion selective electrode analyser, 24 cm wide and under 6 kg, suited to clinics and small labs that want fast electrolytes without a large instrument. It is operated with two buttons, Yes and No, answering prompts on a small screen.

Five models share the design: EasyLyte Na/K, EasyLyte PLUS with chloride, EasyLyte Lithium, EasyLyte Calcium with ionised calcium and pH, and EasyLyte Expand, which adds calcium or lithium to sodium, potassium and chloride. Whole blood, serum or plasma results print in under a minute from 100 microlitres; most models also run diluted urine in 90 seconds.

One serial port, shared by the scanner and the computer

Medica's specification lists no network socket on the EasyLyte. Its results leave through a single RS-232 port, and Medica supplies a serial Y cable so a barcode reader and a PC can use that port together. A serial device server placed next to the analyser turns the PC leg of that cable into a network connection the Catenix gateway can reach.

Sample ID by barcode reader is available on every model except the basic Na/K. Results that carry a sample ID are matched to the patient in the EHR; anything Catenix cannot match waits for review instead of being guessed.

Why the 128-result memory matters

The analyser keeps only its most recent 128 patient results, and the printout is a narrow thermal strip. Capturing each result as it is transmitted gives the lab a permanent copy: Catenix stores every message with its result and, if the clinic's internet is down, holds results on site until they can be forwarded.

Labs using the EasySampler load up to 21 samples with a dedicated STAT position, and can let the sampler repeat out-of-range values automatically.

Normal, Low and High controls

The EasyLyte computes its own QC statistics and stores up to 20 results at each of three control levels. Where control results are sent on, Catenix files them as QC, applies Westgard rules, draws Levey-Jennings charts and holds patient results for an electrolyte whose control has failed.

Questions people ask

Can an EasyLyte connect without a network port?

Yes. Its RS-232 serial port is bridged to the network by a serial device server, which is how the Catenix gateway reaches it.

Does the EasyLyte read sample barcodes?

A barcode reader for sample ID is supported on all models except the Na/K, connected through Medica's serial Y cable.

Will lithium and ionised calcium results come through too?

Whatever your model measures is mapped during setup, including lithium on the EasyLyte Lithium and calcium with pH on the EasyLyte Calcium.
