👉 An exempt fluid is a type of fluid that is excluded from the normal toxicological assessment and regulatory requirements due to its unique properties or specific usage scenarios. These fluids can include biological fluids like amniotic fluid, cerebrospinal fluid, or other bodily secretions that are not typically considered in standard toxicity testing due to their physiological roles or the difficulty in obtaining representative samples. Exempt fluids are often used in medical research, diagnostics, and therapeutic applications where their distinct characteristics necessitate a tailored approach to safety evaluation, ensuring that the fluid's specific properties do not compromise the integrity of toxicity studies or clinical outcomes.
