Connecting a HemoCue WBC DIFF to your LIS or EHR
Quick answer
Yes. HemoCue lists POCT1-A over an Ethernet connection for the WBC DIFF. Catenix receives the white cell count and differential, files control runs as QC and forwards patient results to your EHR or LIS. Order handling and message settings are confirmed on your unit during setup.
Most analysers that give a 5-part differential sit in a lab. The WBC DIFF does it at the point of care: it stains and images white cells in a microcuvette and, within five minutes, reports total white cells plus neutrophils, lymphocytes, monocytes, eosinophils and basophils, each as an absolute count and a percentage.
It takes 10 microlitres of capillary blood from a finger stick or venous EDTA blood, needs no calibration, and runs on mains or six C batteries, and HemoCue points to uses as far out as remote field clinics. The operating manual covers adults and children from three months.

Six numbers per patient, mapped once
Every test produces a total count and five cell types in two units each. During setup we map each of those to the code your EHR expects, so a neutrophil count lands in the neutrophil field and not in a free-text note. The original message is stored next to the result in case anyone needs to check it later.
IDs captured at the bedside
The WBC DIFF records date, time, patient ID, lab ID, operator ID, site ID and control ID. With a barcode reader attached, staff scan the patient wristband or request form rather than typing. Catenix uses the patient ID to match each result to the right record, and anything it cannot match is held for review. The operator ID stays attached to the result.
Controls and the built-in checks
The analyser runs its own self-test, and its image-recognition software warns when it meets cells it cannot identify. Control runs, carrying their control ID, are filed by Catenix as QC, graded with Westgard rules against your targets and charted on Levey-Jennings plots. A failed control holds patient results for that test until someone reviews it. On a site with a weak connection, the gateway keeps results locally through an internet outage.

Questions people ask
Can the HemoCue WBC DIFF connect to a network?
Yes. HemoCue lists POCT1-A over an Ethernet connection, and Catenix receives results that way.
Does the full differential reach the EHR?
Yes. The total count and all five cell types, as absolute values and percentages, are mapped to EHR codes at setup.
Is the WBC DIFF sold in the US?
HemoCue's site says this model is not available in the US and points US buyers to its US range.
