A result becomes defensible only when the observation, control response, timing, and confirmation decision are recorded together. This guide uses the manufacturer IFU for catalogue 610191 as its technical anchor and translates it into practical review questions for professional laboratories.
Start with the product’s documented role
Amies Transport Medium w/o Charcoal is used for collecting, transporting and preserving microbiological specimens. It is formulated to maintain the viability of microorganisms without significant increase in growth, being nonnutritive, phosphate buffered and semi-solid.

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.
Preparation checkpoint
Suspend 9.8 g of powder in 1 liter of distilled or deionized water. Heat to boiling, shake until completely dissolved and dispense into final containers as appropriate. Sterilize in autoclave at 121°C for 15 minutes.
Procedure points worth controlling
After collecting the clinical specimen with a swab, insert one third of the swab into the center of the medium. Then cut the stick and screw down the cap to force the swab to the bottom of the medium. Make sure the cap is screwed firmly on the bottle and keep cool during the transport period. © Liofilchem - Amies Transport Medium w/o Charcoal- Rev.1 / 16.09.2024 Page 2 of 7
Quality control as a decision tool
organisms. SPECIMENS Collect specimens with sterile swabs and transport to the laboratory. Process each specimen using procedures appropriate for that sample. Refer to specific guidelines for more detailed information.
Storage and handling
The powder is very hygroscopic: store the powder at 10-30°C, in a dry environment, tightly closed in its original container and use it before the expiry date on the label or until signs of deterioration or contamination are evident. Store prepared tubes at 2-8 °C.
Know when the result needs confirmation
• Some growth of contaminants may also occur during the long period of transport. • After transportation, the specimen should be inoculated in the proper medium as soon as possible. For optimum results, the time lapse between sample collection and inoculum onto culture medium should be reduced to the minimum. • It may not be suitable for the transport of fastidious organisms. • Gonococci survive well in Amies Transport Medium for at least 6 to 12 hours provided they are not exposed to temperature extremes.
Safety and professional-use reminder
1) For in vitro diagnostic use (IVD). 2) For laboratory professional use only. 3) Operators must be trained and have certain experience. Please read the instructions carefully before using the product. Reliability of assay results cannot be guaranteed if there are any deviations from the instructions in this document. 4) Consult the Safety Data Sheet (SDS) for information regarding hazards and safe handling practices. 5) Do not use if the product or packaging appears to be damaged. 6) Follow standard
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.
