Abstract
Objective: This report presents analytical procedures for detecting banned diuretics in urine of athletes and details the incidences of violations that occurred in the doping control process in Taiwan from 1998 to 2002. Materials and Methods: For screening, urinary samples first underwent acidic and basic extractions before being analyzed by high-performance liquid chromatography (HPLC). Subsequently, if a sample was found to be suspicious for a banned substance, analysis by gas chromatography-mass spectrometry (GC-MS) was undertaken for further confirmation. Results: Of the 5,817 urine samples tested, 12 samples (0.2%)were found to contain banned diuretics, including hydrochlorothiazide (n = 8) and furosemide (n = 4). Among positive cases, sports classified by weight accounted for approximately 70% of the positive cases, in which taekwondo accounted for 33% (n = 4) and weightlifting for 25% (n = 3). Conclusions: The results demonstrate that the abuse of diuretics was primarily occurred in sports with weight classes in Taiwan.
