Laboratory analyzer workflow
Procurement Starting Point
Chemistry analyzer procurement for throughput, reagent model, calibration, QC, LIS interface, service, and uptime.
Use the hospital test mix and daily volume to calculate reportable-test cost, reagent wastage and staffing; validate calibration, QC, carryover, rerun, maintenance, LIS, and downtime recovery.
Compare laboratory equipment around usable workflow and reportable results, not only catalog capacity. Include reagents, QC, validation, LIS, application support, and downtime plan.
Laboratory use should define sample type, daily workload, turnaround time, QC policy, biosafety level, reporting needs, and downtime workaround.
Define Before Buying
- Laboratory use should define sample type, daily workload, turnaround time, QC policy, biosafety level, reporting needs, and downtime workaround.
- Review sample receipt, preparation, loading, run/cycle, QC review, result/report export, cleaning/decontamination, consumable replacement, and shutdown.
- Confirm bench or floor space, ventilation, temperature/humidity limits, power and UPS policy, water/drain/steam where relevant, biosafety placement, reagent storage, and waste handling.
- Replace when reagent supply or assay menu is unsupported, probes/ISE/optics fail frequently, carryover or QC instability rises, LIS/security support ends, or cost per reportable test no longer fits volume.
User Requirement Checklist
- Review sample receipt, preparation, loading, run/cycle, QC review, result/report export, cleaning/decontamination, consumable replacement, and shutdown.
- Laboratory users should test software screens, loading ergonomics, alarm visibility, cleaning steps, contamination control, result reliability, and routine QC or calibration workflow.
- Demonstrate sample loading, calibration/QC, result review, error handling, LIS transfer, cleaning/decontamination, and daily shutdown.
- Laboratory and biomedical teams should review reagent storage, expiry, QC failure response, and service report examples.
Mandatory vs Preferred Specifications
Mandatory requirements
- Specify assay menu, photometric/ISE methods, throughput with and without ISE, sample/reagent capacity, minimum volumes, onboard stability, calibration/QC workflow, rerun/dilution, water and waste needs, LIS, and carryover evidence.
- Test menu or functional range, throughput/capacity, sample or load compatibility, QC/calibration requirements, temperature or speed accuracy where relevant, LIS/data export, safety features, and environmental limits should be stated.
- Consumables, reagents, controls, rotors, objectives, filters, probes, shelves, seals, indicators, or validation materials should be priced separately with replacement intervals.
- Test menu or functional purpose, throughput, sample capacity, calibration/QC method, reagent/consumable requirements, data export/LIS interface, and user permission controls.
- Environmental requirements including temperature, humidity, ventilation, bench/floor space, water/drain where relevant, power, UPS policy, and biosafety workflow.

| Decision | How to Decide | Procurement Risk |
|---|---|---|
| Clinical and performance configuration | Specify assay menu, photometric/ISE methods, throughput with and without ISE, sample/reagent capacity, minimum volumes, onboard stability, calibration/QC workflow, rerun/dilution, water and waste needs, LIS, and carryover evidence. | Avoid comparing headline throughput and reagent price without assay mix, onboard expiry, calibration/QC frequency, rerun/dilution, water/waste, ISE consumables, service response, and reportable-test yield. |
