Urine sample collection for doping control tests is a key component of the World Anti-Doping Agency's fight against doping in sport. However, a substantial number of athletes experience difficulty when having to urinate under supervision. Furthermore, it cannot always be ensured that athletes are actually delivering their own urine. A method that can be used to alleviate the negative impact of a supervised urination procedure and which can also identify urine as coming from a specific athlete is the urine marker test. Monodisperse low molecular weight polyethylene glycols (PEGs) are given orally prior to urination. Urine samples can be traced to the donor by analysis of the PEGs previously given.
The objective of this study was to investigate the use of the urine marker during urine doping control testing.
Two studies investigated athletes' acceptance of this new method via two questionnaires (n = 253). Furthermore, a third study (n = 91) investigated whether ingestion of the marker can identify the urine as coming from a specific person and whether the marker interferes with the detection of prohibited substances.
The results indicate that this new method finds wide acceptance both from athletes who have only heard about the procedure and those who have actually tested the new method. Furthermore, the marker, which can identify urine as coming from a specific person, does not interfere with the detection of prohibited substances.
尿样采集是世界反兴奋剂机构打击运动兴奋剂的关键组成部分。然而，相当数量的运动员在监督下排尿时会遇到困难。此外，也不能总是确保运动员实际提供自己的尿液。一种可以减轻监督排尿程序负面影响并可以识别尿液来自特定运动员的方法是尿液标记物测试。在排尿前口服单分散低分子量聚乙二醇（PEG）。通过分析先前给予的 PEG，可以追踪尿液样本的来源。
本研究旨在调查尿液标记物在尿液兴奋剂检测中的使用。
两项研究通过两份问卷（n=253）调查了运动员对这种新方法的接受程度。此外，第三项研究（n=91）调查了标记物的摄入是否可以识别尿液来自特定的人，以及标记物是否会干扰违禁物质的检测。
结果表明，这种新方法在仅听说过该程序的运动员和实际测试新方法的运动员中都得到了广泛的认可。此外，该标记物可以识别尿液来自特定的人，并且不会干扰违禁物质的检测。
