The losses and redistribution of vitamin C in blood fractions (stabilized with reduced glutathione) during 4 hours of storage at room temperature in the dark was studied among 27 elderly women. Storage did not have a statistically significant (p greater than 0.05) effect on the mean vitamin C levels in cells, plasma and whole blood. The results point to a redistribution of vitamin C among blood fractions. It is concluded that vitamin C concentrations in cells rather than in plasma should be the principal indicator of the vitamin C status when blood (stabilized with reduced glutathione) is stored at room temperature before specimen handling.
对27名老年女性研究了在室温黑暗环境下储存4小时期间（用还原型谷胱甘肽稳定）血液各组分中维生素C的损失和重新分布情况。储存对细胞、血浆和全血中维生素C的平均水平没有统计学显著影响（p大于0.05）。结果表明维生素C在血液各组分间发生了重新分布。得出结论，当在标本处理前于室温储存血液（用还原型谷胱甘肽稳定）时，细胞中而非血浆中的维生素C浓度应作为维生素C状态的主要指标。
