Microbial identification and susceptibility supplies
Identification and antimicrobial susceptibility requests should describe what the laboratory needs to investigate and which method or platform it will use. This group includes biochemical kits, rapid identification reagents, bacterial latex kits, susceptibility discs, MIC gradient strips and automated ID/AST systems. Their consumables and interpretation requirements differ, so a shared application does not make them substitutes.

Separate identification from susceptibility testing
A biochemical identification strip, coagulase reagent and antimicrobial disc answer different laboratory questions. Order them as distinct lines even when they support the same bench. Identify the organism group covered by each ID kit; “bacterial identification kit” rarely supplies enough detail for a useful comparison.
Choose the susceptibility format deliberately
Disc diffusion consumables are specified by antimicrobial agent and disc content. Gradient strips are specified by agent and concentration range. An automated card or panel has its own menu and instrument compatibility. The laboratory method and interpretive standard should guide the request; catalogue similarity cannot establish equivalence.
Include the less visible dependencies
Manual kits may need additional reagents and reading software or database access. Automated systems introduce cards, panels, maintenance materials, interface work and quality-control requirements. Ask for an itemised list of what is included initially and what must be replenished separately. A small initial price is easier to assess when continuing commitments are visible.
Compare automation with the real workload
State daily and peak isolate numbers, organism mix, bench hours and the proportion needing susceptibility testing. Ask how the proposed system handles the required card or panel mix. Request a written menu and configuration rather than assuming every instrument in a family has identical coverage or connectivity.
Review rapid reagent alternatives with the bench
For biochemical or latex products, give the exact target and specimen or isolate context required by the method. Ask for instructions, component sizes, controls and expiry information. Purchasing teams can organise the comparison while the laboratory decides whether the product meets its technical requirements.
Common questions
Are MIC strips the same as antibiotic discs?
No. They are different susceptibility formats. List the agent and required strip range or disc content, then keep the method explicit.
Does a manual ID kit include software access?
It may not. Ask whether reading charts, database access or subscriptions are included and which supplementary reagents are separate.
Can I request automation without choosing a brand?
Yes. Describe workload, organism coverage, susceptibility menu and interface needs. Request a documented configuration and continuing consumables list.
