Connecting a Tosoh G11 HbA1c analyser to your EHR or LIS
Quick answer
Yes. The Tosoh G11 (HLC-723G11) has a bi-directional RS-232C serial port, and its operator's manual describes sending each HbA1c result to a host as it is produced. It can also ask the host about a barcoded tube, so Catenix can tell it which samples the EHR has ordered and then file the results. Tosoh keeps the message layout in a separate host connection manual, so the format is confirmed on your unit during setup.
The G11 measures HbA1c by ion-exchange HPLC, reporting HbF and total HbA1 alongside. A sample takes 60 seconds in variant analysis mode and 30 seconds in standard mode, from 3 microlitres of whole blood drawn through the cap of the primary tube. Tosoh also offers a beta-thalassaemia screening mode.
It starts as a bench unit with a 90-sample loader, about 53 cm wide and 37 kg, and can be upgraded to a 290-sample loader or a laboratory automation model. Racks hold ten tubes, and a separate STAT position takes a priority sample.

Real time or batch: two ways results leave the G11
With communication started on the RS232C screen, the G11 transmits each result as it prints, roughly one a minute in variant mode. Staff can instead pick a date range from the list screen and send it as a batch, or resend a single result after recalculation. The analyser also keeps 800 results in memory and can save more to a USB stick, so nothing depends on the cable alone.
The port is serial only. A serial device server bridges it to the Catenix gateway, with speed, data bits, parity and stop bits set to match the analyser. The gateway holds results on site if the internet is down and reconnects by itself after a network drop.
Barcoded tubes, host requests and unlabelled samples
The built-in reader scans the label on each primary tube. According to the manual, the G11 can send a sample information inquiry with that ID, and when requests come from the host only the requested samples are measured. Catenix answers for barcoded samples from the HbA1c orders in your EHR, and matches each result by sample ID on its way back.
A tube or cup with no barcode is still measured and is sent with the analyser's own measurement number instead. Catenix has no order to pair that with, so the result waits for review.
Control IDs and QC charts
Up to four control IDs can be registered on the G11, by keypad or handheld scanner, so that a sample carrying one of those barcodes is assayed as a control. Tosoh advises running controls at least once a day, ideally at two levels, and sells its own 501RP+ software for Levey-Jennings review. In Catenix, control results are filed as QC, graded with Westgard rules and charted, and a failed control holds patient HbA1c results. Each message is stored with its result.

Questions people ask
Does the Tosoh G11 have an Ethernet port for the LIS?
Its operator's manual describes host communication on the RS-232C serial port. The USB socket is for a memory stick. A serial device server puts the G11 on the network.
Can the G11 run only the samples the EHR has ordered?
Yes. With barcoded tubes and host requests in use, the manual states that only the samples requested by the host are measured.
Is the G11 protocol ASTM?
Tosoh documents it in a separate host connection manual and does not call it ASTM in the operator's manual, so we confirm the format on your analyser.
