Protein testing in instrument cleaning validation
🔍 Principle before disinfection/sterilization: Instrument surfaces must be clean!
-
🔹Residual impurities on the instrument surface → Hinder the effectiveness of disinfectants/sterilizers.
-
🔹Instruments are not clean enough → High-level disinfection/sterilization: INEFFECTIVE, even FAILURE.
-
🔹Remaining organic/inorganic residue: hardens and adheres to the instrument surface upon contact with the high temperature of the autoclave/chemicals of low-temperature sterilization → Difficult to clean the next time…

🧬 What is Protein? Why test for protein?
-
🔹Protein is the main component of contaminants on instruments (blood, tissue, muscle, etc., are primarily composed of protein).
-
🔹The main goal of washing in hospitals is to remove remaining blood and tissue, thus ensuring the success of subsequent disinfection and sterilization processes.
-
🔹Protein residue is a direct measure of organic/microbiological contamination.
-
🔹The causative agent of mad cow disease: Essentially protein!!!
→ The purpose of cleaning is to remove organic dirt in all forms! → Protein Assessment: Superior, the preferred choice!
❓ So what does "CLEAN" mean?
Clean when the protein residue is < 5 µg/ 1 side of the instrument. You can observe this in the image below.
🔬 Solution: Pro 1 Micro Protein Test - Standardized Cleanliness Assessment
💡The Pro 1 Micro is an advanced system that enables precise protein quantification to validate cleaning processes in critical environments. This device uses technology to quickly detect and quantify protein residue, providing real-time results.
-
🔹High sensitivity: Capable of detecting protein residue at extremely low concentrations, ensuring even the smallest traces are identified and removed during cleaning.
-
🔹Fast results: Unlike other methods that can take hours, Pro1 Micro provides near-instantaneous data, allowing for immediate adjustments to cleaning procedures.
-
🔹Easy to use: Designed for busy environments, the swab-like design allows access to hard-to-reach areas during instrument washing.
-
🔹Protein quantification system for post-wash cleaning effectiveness assessment, designed for use after cleaning on any surface. Its design allows access to hard-to-reach areas in complex instruments (such as serrated edges or box joints)...
