👉 Cytokine-Inducible Leukocyte Cell Viability Calibrator (CLCuV) is a diagnostic tool used in clinical laboratories for detecting leukocytes that have been activated by cytokines, such as interleukin-12 and tumor necrosis factor-alpha. It uses the presence of specific antibodies to identify cells that are capable of responding to these cytokines. This allows for the determination of whether or not a patient has an infection or cancer, which is crucial in diagnosing
