Development of a Screening Test for L-Dopa and Its Metabolites in Urine

[摘要] A simple screening test, sensitive to o -dihydroxyphenyl groups in the urine, was developed for use in monitoring patients with Parkinson's disease who are treated with L-dopa. Compounds measured by this test include dopa, dopamine, 3,4-dihydroxyphenylacetic acid, epinephrine, and norepinephrine. Parallel quantitative experiments, in which ion-exchange chromatography was used, followed by fluorometry and colorimetry, establish the validity of the strip-test results. The test is designed to be used by physician or patient, as well as by clinical laboratory personnel.
