Bromodeoxyuridine (BrdU) is a nucleoside analog that competes with thymidine for incorporation into DNA, and used in the detection of proliferating cells.

Methylhippuric acid is an acyl glycine. Acyl glycines are normally minor metabolites of fatty acids. In certain cases the measurement of these metabolites in body fluids can be used to diagnose disorders associated with mitochondrial fatty acid beta-oxidation. Methylhippuric acid is a metabolite of xylene which is an aromatic hydrocarbon widely used as a solvent.
