What does a positive protein residual test indicate about a cleaned instrument?
Answer: Organic soil remains and cleaning was inadequate
A positive protein test detects residual organic contamination, indicating inadequate cleaning.
What is the purpose of ATP bioluminescence testing in decontamination?
Answer: To detect residual organic contamination by measuring ATP levels
ATP testing detects adenosine triphosphate on surfaces, providing a rapid quantitative measure of cleaning effectiveness.
How should visual inspection of cleaned instruments be performed?
Answer: Using a magnifying glass or illuminated magnifier under adequate lighting
Inspection requires magnification and bright lighting to detect residual soil, damage, or corrosion.
What is a Tosi test (Wash Check) used to verify?
Answer: Effectiveness of the washer-disinfector cleaning cycle
Tosi tests use standardized test soils run through the washer to verify cleaning effectiveness.
Why is it important to test cleaning solution concentration during manual cleaning?
Answer: To verify detergent is at manufacturer-specified concentration for optimal cleaning
Testing ensures the solution is mixed to the correct dilution ratio for optimal enzyme activity and cleaning.
What action should be taken when a cleaning verification test fails?
Answer: Document failure, remove load for recleaning, investigate cause, and retest after corrective action
A failure requires documentation, recleaning, root cause investigation, corrective action, and successful retesting.
