Connecting a Dymind DF55 to your LIS or EHR
Quick answer
Yes. Dymind's own DF55 sheet says the LAN port supports the HL7 protocol and that a bi-directional LIS is supported. Catenix takes that HL7 feed on the lab network and passes each count to your EHR or LIS under the right sample ID. How your unit handles orders is confirmed during setup.
Dymind calls the DF55 a mini 5-part analyser. In a case 364 mm wide and weighing 28 kg it runs up to 60 tests an hour from 20 microlitres of blood, in whole blood, capillary whole blood or pre-diluted mode.
White cells are split into five populations by flow cytometry with tri-angle laser scatter, and basophils get an optical channel of their own. The result is 25 reportable parameters, six research parameters, three histograms and four scattergrams, with up to 100,000 records kept on the analyser.

| Reportable values | 25, plus 6 research parameters |
| Speed | Up to 60 tests per hour |
| Blood needed | 20 microlitres |
| Host link | 1 LAN port, HL7, bi-directional LIS |
| Other ports | 4 USB |
| Records held | Up to 100,000 |
One network cable, HL7 on it
The DF55 has a single LAN port and Dymind names HL7 as the protocol it carries, so no serial adapter is involved. The Catenix gateway sits on the same network as the address the analyser reports to. If a switch is restarted or a cable is knocked out, the gateway picks the connection up again without anyone logging in.
Dymind lists the LIS link as bi-directional. Whether your DF55 looks up the tests requested for a sample, or simply reports what it ran, is settled on your unit during setup. In both cases a count is filed against its order by sample ID, and a count that has no order to land on is parked for a person to review.
Research parameters stay out of the record
Alongside the 25 reportable values the DF55 produces six research ones: ALY, LIC and NRBC, each as a count and a percentage. During setup every code the analyser sends is mapped to the matching code in your EHR, and the research values are simply left unmapped unless your lab decides otherwise.
What happens to DF55 control runs
A control run is not a patient. Catenix files it as QC, checks it against your targets with Westgard rules and plots it on a Levey-Jennings chart. When a control fails, patient results for the affected test are held back until the lab has dealt with it.
Each HL7 message is kept with the result it produced. Should the internet connection fail, results collect on site and move on once the line is back.

Questions people ask
Does the Dymind DF55 use HL7?
Yes. Dymind's DF55 sheet says the LAN port supports the HL7 protocol.
How many ports does the DF55 have?
One LAN port for the LIS link and four USB ports.
Is the DF55 a 3-part or 5-part analyser?
It is 5-part, using flow cytometry with tri-angle laser scatter and a separate basophil channel.
