WHAT DOES ASSAY MEAN IN ENGLISH?

Assay

An assay is an investigative procedure in laboratory medicine, pharmacology, environmental biology, continuous delivery and molecular biology for qualitatively assessing or quantitatively measuring the presence or amount or the functional activity of a target entity which can be a drug or biochemical substance or a cell in an organism or organic sample. The measured entity is generally called the analyte, or the measurand or the target of the assay. The assay usually aims to measure an intensive property of the analyte and express it in the relevant measurement unit. If the assay involves addition of exogenous reactants then their quantities are kept fixed so that the quantity of the target is the only limiting factor for the reaction/assay process, and the difference in the assay outcome is used to deduce the unknown quality or quantity of the target in question. Some assays may be similar to or have overlap with chemical analysis and titration. But generally, assays involve biological material or phenomena which tend to be intrinsically more complex either in composition or in behavior or both.

Definition of assay in the English dictionary

The first definition of assay in the dictionary is to subject to chemical analysis, as in the determination of the amount of impurity. Other definition of assay is to attempt. Assay is also to test, analyse, or evaluate.
