A test device for detecting bilirubin in serum is provided which comprises a carrier and, incorporated therewith, a composition comprising a diazonium salt, p-toluenesulfonic acid and dyphylline. The test device is free of the undesirable characteristic of nonuniformity of color development when reacted with a test sample. Uniform color development provides a more accurate and reliable quantitation of serum bilirubin. A method of making and a method of using the device are likewise disclosed. |
