Haematology & ESR analysers
Choosing an analyser begins with the work your laboratory needs to perform. This group brings together three-part and five-part differential instruments and ESR systems, but each has a different specification. Write down the required outputs, expected workload and accepted collection format before comparing equipment. A quote should identify the exact model and configuration, with its recurring consumables and quality materials.
Useful details for your quote
- Required differential or ESR method
- Daily samples and peak workload
- Sample modes, tubes and loading requirements
- Verified parameters and result flags
- Connectivity, bench and power requirements
- Included accessories and starter supplies
Compare like-for-like capabilities
A three-part and five-part differential are not interchangeable descriptions. Ask for the exact parameter list and the functions included in the proposed model. Optional modes should be identified separately. Do not assume a capability is included simply because it appears elsewhere within a manufacturer’s range.
Account for the operator’s workflow
Consider manual versus automated loading, sample identification and result review alongside nominal throughput. Ask how the stated throughput was defined and whether it represents the configuration offered. Procurement can record these requirements without assuming that the highest advertised speed is the best fit for every laboratory.
Give ESR its own requirements
An ESR instrument needs its stated method, accepted tube types, capacity and quality-control requirements checked separately from a blood counter. If replacing an existing system, document any change in specimen format or accessories. Do not assume collection consumables can be carried over unchanged.
Request the full instrument package
The proposal should distinguish the analyser from accessories, initial reagent quantities, controls, calibrators and separately quoted training or installation. Ask which computer or printer interfaces are included. A base-unit price without these details gives an incomplete picture of the equipment your laboratory would receive.
Evaluate the ongoing supply
Record reagent references, pack options and quality-material availability for the exact model. Ask for the relevant manufacturer documents and confirm commercial support arrangements in the offer itself. Comparing a complete operating requirement is more useful than comparing equipment prices while leaving recurring supplies undefined.
Common questions
Should a small laboratory only consider three-part systems?
No. Compact five-part systems exist. The required outputs, staffing and workload should guide the specification, with the exact model assessed on its own merits.
Are ESR tubes the same for every analyser?
No universal compatibility should be assumed. Obtain the collection and consumable requirements for the offered ESR method and model.
What information helps compare quotations?
An exact model, included functions, parameter list, loading arrangement, consumables and itemised accessories. Confirm what is optional and what is part of the offered configuration.
