Zusammenfassung:Urobilinogens, optionally in the presence of bilirubin, are detected with a novel diagnostic agent comprising A. AT LEAST ONE STABLE DIAZONIUM SALT CONTAINING A PHENYL-, PYRROLE, OR PYRAZOLE RING ANNELLATED WITH AN AROMATIC SYSTEM IN A MESOMERIZABLE AND STERICALLY UNHINDERED POSITION OR SUBSTITUTED DIRECTLY OR VIA A VINYLENE RADICAL WITH AN AROMATIC SYSTEM, OR B. A PYRIDINE OR PYRAZOLE DIAZONIUM SALT SUBSTITUTED IN A MESOMERIZABLE POSITION WITH AT LEAST ONE POLYATOMIC ELECTRON DONOR GROUP HAVING AT LEAST ONE MESOMERIZABLE ELECTRON PAIR WITH THE PROVISO THAT THE SUM OF THE Hammett sigma values for all the substituents, and hetero atoms does not exceed the value of +0.6.
