Control reagent for test strips for determining urobilinogen in urine
First Claim
1. An artificial human urine control reagent for analytical test strips used in analyzing human urine, comprising a mixture of a component selected from 2, 4-dimethylpyrrole-3-carboxylic acid, alkali metal salts thereof and alkaline earth metal salts thereof as a substitute for naturally occurring urobilinogen in human urine and at least one other component which is or simulates a diagnostically relevant component of human urine, the ratio of urobilinogen substitute to said other at least one component simulating conditions naturally occurring in human urine.
