Getting Tosoh HLC-723GX HbA1c results into your EHR or LIS

Quick answer

Yes, by serial link. Tosoh lists the HLC-723GX among the analysers that connect over RS-232C to its 501RP+ data management PC. Catenix receives the same serial output through its gateway, matches each HbA1c result to its order and sends it to your EHR or LIS. No host specification for the GX is public, so the message format and port settings are confirmed on your unit during setup.

The GX is Tosoh's compact HPLC analyser for sites with a modest HbA1c workload. It takes up to ten samples per batch and needs 2.2 minutes for each, which works out at 27.3 samples an hour. The first result appears after 6.6 minutes and a full batch of ten is finished in 26.4.

At 37 cm wide and 25 kg it fits on a short stretch of bench. It pierces the cap of the primary tube, takes 3 microlitres of whole blood, and reports stable HbA1c together with HbF. Tosoh's US literature marks it as not FDA cleared and for sale only outside the United States.

A small-batch analyser with one serial port to plan for

Because the GX talks over RS-232C, it reaches the Catenix gateway through a serial device server placed beside it. Each batch brings up to ten results. If the clinic's internet is down they stay on site and go forward later, and the gateway picks the connection up again after a network drop.

Tosoh describes its own link to the GX as bidirectional, but nothing public says whether the analyser will take requests from another host. We therefore plan a GX connection around results, and check on your unit whether more is possible.

Why the optional barcode reader is worth having

Tosoh offers positive sample identification on the GX through a barcode reader, sold as an option. Catenix files HbA1c results by matching the sample ID on each message to an order in the EHR, so a scanned ID that equals the order's accession number is the dependable route. A result whose ID matches no order is held for review.

On a GX without the reader, how samples will be identified is agreed and tested during setup, before patient results flow.

Variant flags, controls and the record kept

HbA1c stays reportable on the GX when common haemoglobin variants are present, and the result is flagged. The analyser has more than 18 flags that a lab can tailor, plus a buffer monitor with an adjustable alarm. Catenix stores each message with its result, so what the analyser sent can be checked later.

Tosoh's optional data management software adds Levey-Jennings charts and an audit trail. Where control results reach Catenix they are filed as QC, graded with Westgard rules and plotted, and a failed control holds patient HbA1c results.
