A useful QC plan does more than record that a control passed; it explains what the control protects and what happens when it fails. This guide uses the manufacturer IFU for catalogue 163932 as its technical anchor and translates it into practical review questions for professional laboratories.
Start with the product’s documented role
Actinomycete Agar is a medium used for the isolation of actinomycetes from soil and water.

Design the workflow before opening the pack
Define the sample type, inoculum or preparation step, incubation conditions, control organisms, reading window, confirmation pathway, and acceptance criteria in the SOP. Record the catalogue number, lot, expiry, analyst, equipment, and any deviation that could change interpretation.
Procedure points worth controlling
For water examination, filter the sample through a sterile membrane (pore size 0.45 μm). Place the membrane onto the agar surface. Incubate at 30 ± 2°C for up to 72 hours. The membrane filter method can also be used for the isolation of actinomycetes from soil samples as follow: Inoculate the surface of a membrane with a soil suspension and overlaid the Actinomycete Agar plate with the inoculated filter. Incubate at 30 ± 2°C until growth ofbacteria is observed (72 hours). Then, remove the membrane filter and re-incubate the agar medium for 48-72 hours to allow the development of the isolated actinomycete colonies. Such

A practical pre-release checklist
- Current IFU revision and catalogue code verified
- Receipt, storage, lot, and expiry documented
- Controls and acceptance criteria defined before testing
- Reading time and observations recorded without forcing an ambiguous endpoint
- Confirmation and deviation actions linked to the laboratory SOP
Final perspective
Useful technical content should help a laboratory make a better-controlled decision, not replace the IFU or validated method. Confirm the current manufacturer documentation and local regulatory requirements before implementation.
