What Does UF Stand For?

UF stands for Uncertainty Factor In Oral RfD

Uncertainty Factor (UF) in Oral Reference Dose (RfD) refers to a numerical value used in toxicological assessments to account for variability and uncertainty in the data used to establish the RfD. It is applied to ensure safe exposure levels by providing a margin of safety when estimating the potential health effects of chemical substances through oral intake. The UF typically incorporates factors such as inter-species differences, intraspecies variability, and long-term exposure impacts, thereby enhancing the reliability of risk assessments and safeguarding public health.
