A process for the preparation of a fluid control, with which the presence of urobilinogen is simulated, as well as the resulting liquid control and their use for monitoring reactions

摘要

A urobilinogen control composition, control preparation a device and a method for preparing a liquid control in which the presence of urobilinogen is simulated are disclosed. A method for simulating the presence of urobilinogen in a liquid and a liquid control in which the presence of urobilinogen is simulated are also disclosed. The control composition incorporates compounds reactable with p- dimethylaminobenzaldehyde to produce a color change such that the presence of urobilinogen is simulated. Indoles which are selectively substituted at the 1, 2 and/or 5 positions are used. The control may be in the form of a solution, but is advantageously incorporated with a carrier, such as a matrix or tablet, to provide a device. IMAGE
