Molecular TB testing equipment and cartridges
Molecular TB purchasing should separate instrument hardware from the assay consumables used on it. This group covers GeneXpert-related equipment requests and Xpert MTB/RIF or Ultra cartridge inquiries. Give the current platform details and full assay name so the offered configuration can be checked, especially when expanding an installation or changing the cartridge version.
Useful details for your quote
- New system, additional module or consumable-only requirement
- Installed platform model and relevant software details
- Exact assay name and product reference
- Workload and requested kit quantities
- Controls, accessories and additional materials
- Site requirements, support scope and lot expiry
Hardware and test names are different identifiers
An instrument family name does not define an assay. Request the platform configuration separately from Xpert MTB/RIF or Ultra cartridges, and keep the full product reference on each consumable line. Compatibility should be confirmed against the offered instrument and current documentation, rather than inferred from similar wording.
Describe the equipment change
Say whether you need a complete new installation, additional capacity or a replacement for an existing module. Include the current system configuration where known. Ask the offer to distinguish hardware, computer or software, accessories and any work required to integrate the change. This helps prevent a module-only price being compared with a complete-system quotation.
Count tests and accompanying materials
For consumables, state the exact assay version, tests per kit and kits required. Ask which materials are included and which are separate. Controls and other supporting products should have their own lines when needed. Estimated monthly use and minimum shelf life help avoid an oversized order that cannot be used efficiently.
Put equipment services into writing
Request a documented scope for installation, verification, training, maintenance and interface work if those are required. State site constraints and power arrangements so the proposed equipment can be reviewed. None of these commitments should be assumed from the instrument price or a manufacturer brand name.
Check the offered product version
Manufacturer materials can differ by country and revision. Ask for the instructions and product identity corresponding to the actual offer. The laboratory should review intended use and compatibility before approving an assay change, while purchasing verifies quantities, expiry and quoted exclusions.
Common questions
Can a module be quoted separately?
Describe the installed platform and the reason for the module request. Ask for compatibility and the full replacement or expansion scope to be confirmed.
Are MTB/RIF and Ultra simply different pack names?
Keep them as distinct assay identities. Do not approve a substitution without review of the actual product and platform requirements.
Should we include monthly test volumes?
Yes. They help define kit quantities and equipment capacity, but do not replace the exact assay specification.
