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