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
