The global Bioanalytical Testing Services size is projected to reach a CAGR of 12.59% from 2022-2028. Bioanalysis involves quantitative measurement of xenobiotics, like small molecule drugs and their metabolites and biological molecules. Bioanalytical testing services are used in the development and validation of robust bioanalytical methods in body fluids and tissue specimens. These tests are used to support pre-clinical and Phase I through Phase IV clinical trials.

Pesticides are degraded by many different mechanisms. Physical, chemical, and biological agents play significant roles in the transformation of insecticide, herbicide, and fungicide molecules to various degradation products. The physical and chemical properties of the degradation products are also different from those of the parent compound, and their fate and significance in the environment also are altered with the structural changes.
