Abstract
Blood osmolality is considered the gold standard hydration assessment, but has limited application for technical and invasive reasons. Paired antecubital-venous blood and fingertip-capillary blood were collected pre- and 30 min post-drinking 600 mL water in 55 male/female participants. No bias (0.2 mOsmo/kg, limits of agreement = -2.5 to 2.8 mOsmo/kg) was found between sampling methods, with high linear correlation (Spearman's r = 0.95, P < 0.001). Capillary blood sampling offers an accurate less-invasive method for determining serum osmolality than venous blood sampling.
血液渗透压被认为是水合评价的金标准，但由于技术和侵入性原因，应用有限。55名男性/女性受试者在饮用600毫升水前和30分钟后采集配对的婚前静脉血和指尖毛细血管血。采样方法间无偏倚(0.2 mOsmo/kg，一致性限= -2.5 ~ 2.8 mOsmo/kg)，线性相关性高(Spearman’s r = 0.95, P
期刊介绍：
Applied Physiology, Nutrition, and Metabolism publishes original research articles, reviews, and commentaries, focussing on the application of physiology, nutrition, and metabolism to the study of human health, physical activity, and fitness. The published research, reviews, and symposia will be of interest to exercise physiologists, physical fitness and exercise rehabilitation specialists, public health and health care professionals, as well as basic and applied physiologists, nutritionists, and biochemists.
