A protein residue test for checking sampled surfaces after cleaning. Product reference 5646854. The existing catalogue states a 10-second visual response; confirm the current product IFU for sampling, readout and acceptance criteria.
Check residual protein after cleaning
The MEDIWISH Protein Residue Test, reference 5646854, is intended for residual-protein checks on sampled surfaces after cleaning. It addresses residue remaining at the sampled location, a different question from cavitation activity in an ultrasonic bath.
A result applies to the sample and conditions of the method. It does not establish that the entire instrument is free of all contamination, disinfected or sterile, and it does not replace the facility's complete cleaning verification and release procedure.
Product parameters and current instructions
The existing catalogue for this reference states a sensitivity of 0.1 μg, a 10-second visual response and a colour change from light brown to blue. It describes surface sampling with a swab followed by contact with the reagent. These stated values are retained; they must not be transferred from or to another protein test.
Interpret and record within the method
Use the current instructions to distinguish valid, positive, negative and invalid outcomes. Record the product reference and lot, expiry, sampled item and location, test conditions, reading time and result. A result indicating residue calls for review under the facility procedure; a negative result does not prove absence of all protein outside the method's detection and recovery limits.
How this differs from an ultrasonic indicator
MZS-5635 cavitation indicator vials assess a qualitative response at a defined bath location. They do not sample protein from an instrument. A protein residue test and a cavitation check can answer separate monitoring questions; neither substitutes for the other.
Use the comparison of cleaning monitoring methods to distinguish their purposes, or return to cleaning validation and monitoring products.
Questions before ordering
Is this an ATP or sterility test?
No. This listing concerns residual protein. It does not establish ATP content, microbial kill or sterility.
Can one result represent every instrument surface?
No. Interpretation depends on the sampled location and the validated sampling and test conditions. Confirm suitability for the intended instrument, surface or channel in the current instructions.
Which documents and pack details should I request?
Ask for the current IFU and specification for reference 5646854, the supplied components, quantity per pack, storage and shelf life, and documentation required for your intended market. Do not assume the specification of another MEDIWISH protein test applies.
Request product documentation and a quotation. Include reference 5646854, intended sample, instrument or surface, destination country and required quantity.
Send your request with the product name or model, required specifications, quantity and destination country. Product configuration and payment and delivery terms are agreed when the order is confirmed.
