Beschreibung
Zusammenfassung:	The present invention relates to a method for the preparation of test aids for detecting substances to be analysed by means of redox reactions, a single-component indicator being used as indicator substance and, in addition, oxidizable aromatic amino or hydrazinol compounds which are not capable of coupling with themselves being added to the test aid as decolorants. The addition of the decolorant prevents the appearance of a blank colour value of the test aid. The addition of relatively large quantities of the decolorant makes it possible to adjust the sensitivity of the test aid precisely.
