Abstract
The present invention involves the use of certain indole sulfonates in a test control method for the Ehrlich reagent used in diagnostic tests for urobilinogen. The indole sulfonates exhibit unique solubility characteristics which facilitate their application to dry carrier matrixes with subsequent rehydration during their use in the test control method.
