In this consensus document, we attempt to make recommendations that are based on bioanalytical best practices and statistical thinking for development and validation of LBAs.

The development and validation of ligand binding assays used in the support of pharmacokinetic studies has been the focus of various workshops and publications in recent years, all in an effort to establish a guidance document for standardization of these bioanalytical methods. This summary report of the workshop from 2003 focuses on the issues discussed in presentations and notes points of discussion and areas of consensus among the participants.
