摘要：A novel test composition, device and method for determining the presence ofurobilinogen in a test sample. The composition is capable of producing a detectableresponse, such as a change in color or change in light absorption, thus indicating thepresence of urobilinogen, both on a qualitative and a semi-quantitative basis. Briefly, thecomposition comprises para-di(lower alkyl)aminobenzaldehyde as an indicatorcompound, a buffer substance capable of producing a pH of about 0.5 to 3, and acompound having the structure ##STR1## in which X is O or S, and in which R and R', sameor different, are lower alkyl, or R and R' together are lower alkylene or ##STR2##wherein n is an integer of 1 to about 6. The device comprises a carrier matrix incorporatedwith the composition. The method of use comprises contacting a test sample with thecomposition or device and observing any detectable response formed therein.
