Laboratory analyzer workflow
Procurement Starting Point
ABG analyzer procurement for cartridge or reagent model, QC, calibration, connectivity, downtime cover, and service.
Compare cost per reportable test at real workload, including standby use and QC; validate sample handling, clot/error recovery, critical results, interface, operator lockout, and emergency support.
Separate mandatory clinical applications from optional software packages. Require site-planning documents, high-cost component warranty, DICOM testing, and acceptance image-quality baseline before award.
Clinical use should define modality-specific cases, patient volume, reporting workflow, emergency use, contrast workflow where relevant, and image storage/retrieval expectations.
Define Before Buying
- Clinical use should define modality-specific cases, patient volume, reporting workflow, emergency use, contrast workflow where relevant, and image storage/retrieval expectations.
- Review patient scheduling, preparation, acquisition, image reconstruction/review, DICOM transfer, reporting, archiving, repeat-image handling, cleaning, and downtime response.
- Confirm power, UPS policy, HVAC, shielding or MRI safety zoning, room size, control area, floor loading, delivery route, network drops, PACS/RIS readiness, and service clearance.
- Replace when cartridge supply or analyte menu is unsupported, calibration/QC failures rise, sensors/electrodes become unreliable, connectivity/security ends, or cost per reportable result becomes uncompetitive.
User Requirement Checklist
- Review patient scheduling, preparation, acquisition, image reconstruction/review, DICOM transfer, reporting, archiving, repeat-image handling, cleaning, and downtime response.
- Radiology users should test positioning, protocol selection, image review, dose or safety indicators, report/export workflow, contrast workflow where applicable, and ergonomic impact during peak lists.
- Script normal setup, alarm event, accessory change, battery operation, cleaning-sensitive part removal, error log review, and handover documentation.
- Include nurses/clinicians and biomedical engineering; score setup time, alarm clarity, accessory durability, and first-line troubleshooting.
Mandatory vs Preferred Specifications
Mandatory requirements
- Specify measured analytes, sample volume and type, time to result, throughput, calibration and QC method, cartridge/reagent model, clot detection, sample identification, data connectivity, and environmental limits.
- Image-chain configuration, clinical application package, dose or safety controls where relevant, workstation/reporting workflow, DICOM/PACS/RIS connectivity, cybersecurity, and site planning requirements should be specified.
- High-cost components such as tube, detector, probe, coil, workstation, injector head, chiller, software licenses, and service tools should have clear warranty and replacement pricing.
- Patient range, measured or delivered parameters, alarm limits and priorities, display/trends, battery runtime, mounting/transport requirements, cleaning compatibility, and accessory package.
- Power and gas requirements where relevant, network/central station/interface scope, cybersecurity policy, data export, and downtime workflow.
- PM procedure, performance verification method, required analyzers/test tools, calibration needs, spare parts, and loaner/escalation policy.
Preferred or optional requirements
- Advanced modes, central monitoring, telemetry, remote viewing, extended battery, neonatal/pediatric packages, additional modules, or interface licenses.
- Extended accessory replacement coverage, uptime support, or training package.
Configuration Choices

| Decision | How to Decide | Procurement Risk |
|---|---|---|
| Clinical and performance configuration | Specify measured analytes, sample volume and type, time to result, throughput, calibration and QC method, cartridge/reagent model, clot detection, sample identification, data connectivity, and environmental limits. | Avoid comparing reagent pack price without usable-test yield, onboard expiry, standby/calibration consumption, QC frequency, sample rejection, electrode coverage, and after-hours service. |
