What does a reading of 0 to 10 RLU indicate?

A reading of 0 to 10 Relative Light Units (RLU) indicates a surface that is considered clean. RLU measurements are commonly used in hygiene monitoring to assess the presence of biological contamination. In this context, a lower RLU reading reflects that there are fewer or no residual contaminants on the surface, which suggests effective cleaning and disinfection practices.

The range of 0 to 10 RLU typically signifies that the surface is free from significant microbial presence, thus minimizing the risk of infections or illness associated with pathogens. As such, this range provides reassurance that necessary cleaning protocols were adequately implemented and that the area meets hygiene standards.

In contrast, higher RLU readings would signal potential contamination or increased risk of pathogens, highlighting the importance of maintaining rigorous cleaning protocols, especially in environments requiring high levels of cleanliness, such as those involved in trauma and crime scene remediation.
