    A novel method uses coagulable blood to contaminate test objects for disinfection efficacy testing. This technique simulates real-world conditions, improving microbiological evaluations of surface disinfectants.

    Area of Science:

    • Microbiology
    • Biotechnology

    Context:

    • Disinfection efficacy testing requires realistic contamination models.
    • Coagulated blood presents a challenging matrix for disinfectant evaluation on surfaces like medical instruments.

    Purpose:

    • To describe a new method for contaminating test objects with coagulable blood.
    • To enable more accurate microbiological evaluation of disinfectants on surfaces where blood may coagulate.

    Summary:

    • The method involves heparinizing blood, storing it at 0°C, and adding test organisms.
    • Coagulation is initiated with Protamin 1000, followed by contaminating test objects.
    • Objects are then incubated in a humid chamber at 20°C for 15 minutes to allow full coagulation.

    Impact:
