enzymatic assays

Enzymatic assays are laboratory tests used to measure the activity of specific enzymes—proteins that speed up chemical reactions—within a sample. By adding a substrate (a substance the enzyme acts upon) and observing how quickly it is converted into a product, scientists can determine how active or functional a particular enzyme is. These tests help diagnose diseases, monitor treatments, and understand biological processes. The results are usually expressed as the rate or amount of product formed over time, providing valuable information about health or the presence of specific conditions.
