Abstract
4-Fluoro-3-nitrobenzenediazonium salts in test compositions capable of specific and sensitive determination of urobilinogen without any interference of bilirubin in an aqueous solution or body fluid such as urine. The diazonium salts have incorporated special stabilizing anions. In addition to a 4-fluoro-3-nitrobenzene diazonium salt, the test compositions preferably include an acid constituent capable of producing an acid pH upon contacting the solution to be tested. The test device comprises a bibulous carrier member, such as paper impregnated with the test composition in dry form.
