title: Application of "tile reaction" test for screening dapsone in urine.
abstract: A modified tile reaction test for monitoring self administration of DDS by leprosy patients is described. 385 Urine samples collected at 24 hours after a single dose and at 24, 48 and 72 hours after daily doses of 25, 50, 100 mg were screened for the presence of DDS by this test and the corresponding DDS/C ratios were studied for comparison. Patients compliance was assessed on 268 urine specimens collected on surprise visits. The feasibility of application of this test in field situations is discussed.
