A bioassay is a type of test that measures the biological activity of a biotherapeutic drug. The purpose of a bioassay is to determine the potency of the drug and to ensure that it is safe and effective for use in humans. An activity bioassay is a type of bioassay that measures the quantity of a substance, such as a protein or enzyme.  On the other hand, a functional bioassay is a type of bioassay that measures the quality of a substance, such as its biological activity, and is used to determine the potency of the substance.

A Cytotoxicity assay is a type of test that measures the ability of a substance to cause cell damage or cell death. 

An ADCC (Antibody Directed Cell-Mediated Cytotoxicity) bioassay is a type of bioassay that measures the ability of an antibody to induce cell-mediated cytotoxicity. The assay is based on the ability of the antibody to bind to a target cell and recruit immune cells to destroy the target cell.
