Background:Proper hydration is vital for both exercise and general health. Although various methods for hydration assessment exist, many are not valid for either use or never tested.
Introduction:{'sup': '©', '#text': 'The purpose of this study was to determine whether the uChek smart phone application can be used to diagnose underhydration based on elevated urine specific gravity (USG) assessed by refractometry.'}
Methods:{'sup': '©', '#text': 'One hundred forty-seven (n\u2009=\u2009147) fresh human urine samples from young and middle-age adults were analyzed for USG with a refractometer and the uChek application by reading the Siemens Multistix 10G urine reagent strip.'}
Results:{'sup': '©', '#text': 'Bland-Altman analysis showed agreement of the two methods of assessment. Overall diagnostic ability of the uChek to identify underhydration was fair (area under the curve 79%). However, the sensitivity to correctly identify underhydration was poor (60%) as well as the specificity of correctly identifying euhydration (53%).'}
Conclusion:{'sup': '©', '#text': 'The uChek application does not accurately detect underhydration.'}
适当补水对运动和总体健康都至关重要。尽管存在多种补水评估方法，但许多方法要么无效，要么从未经过测试。
本研究的目的是确定uChek智能手机应用程序是否可用于根据通过折射法评估的尿比重升高来诊断脱水。
用折射仪和uChek应用程序通过读取西门子Multistix 10G尿液试剂条对147份来自年轻和中年成年人的新鲜人类尿液样本进行尿比重分析。
布兰德-奥特曼分析表明两种评估方法具有一致性。uChek识别脱水的总体诊断能力一般（曲线下面积为79%）。然而，正确识别脱水的敏感性较差（60%），正确识别水合正常的特异性也较差（53%）。
uChek应用程序不能准确检测脱水。
