The colour reaction of di-methyl-amido-benzaldehyde with metabolites in urine (especially with urobilinogen), discovered and published by Paul Ehrlich 80 years ago has lost nothing of its significance as a simple, practical, quick, qualitative test.

Despite the technical simplicity of the test, certain rules have to be adhered to. Ehrlich's aldehyde reagent has also won importance in chromatography. The modern test-strip technique permits an easy and rapid examination for urobilinogen (and bilirubin).
