Plasma 25-hydroxycalciferol levels were measured in ten normal subjects at approximately 6-weekly intervals for 1 year. The mean annual level was 18.4 ng/ml with a seasonal variation from 14 to 26 ng/ml. These values correlated well with serial estimates of personal UV radiation dose previously measured by polysulphone film badges.
对10名正常受试者的血浆25-羟基维生素D水平进行了为期1年的测量，测量间隔约为6周。年平均水平为18.4纳克/毫升，季节性变化范围为14至26纳克/毫升。这些数值与之前用聚砜薄膜徽章测量的个人紫外线辐射剂量的系列估计值密切相关。
