New Tests for Bile and Detection of Bile in Serum and Urine

Abstract 1. New tests proposed for the detection of bilirubin have been described. 2. Application of some of the proposed tests on pathologic and normal serum and urine have been demonstrated. 3. The diazochlorides of certain amines previously reported as failures to detect bilirubin have been shown to be successful and have been applied to bile, serum, and urine. 4. Comparative sensitivity of the proposed tests and the most generally accepted tests for bilirubin in test solutions, pathologic serum, and urine have been given. 5. Spot tests suitable for the detection of bilirubin in pathologic urine have been presented.
