对199名健康人的全血、红细胞和血浆中的硒含量进行了调查，发现全血、红细胞和血浆中的硒含量分别为101.1微克/升(全血)、133.1微克/升(红细胞)和78微克/升(血浆)。在62个尿样中，以微克/克肌酐表示的硒水平为11.4。男性平均全血硒浓度为104.5±23.2微克/升，明显高于女性的96.9±21.2微克/升。红细胞、血浆和尿硒水平在男女受试者之间无明显差异。红细胞与全血硒水平(r=0.879；p<0.001)、全血和血浆硒水平(r=0.806；p<0.001)呈显著的线性相关。尿和全血之间以及尿和血浆硒浓度之间存在较弱但仍显着的线性相关性。血液和尿液中的元素水平相对较低，可能是由于饮食中缺乏元素所致。
Selenium (Se) levels in whole blood, red blood cells, and plasma taken from 199 healthy subjects were investigated and found to be 101.1 micrograms/1 (whole blood), 133.1 micrograms/1 (packed red blood cells), and 78.0 micrograms/1 (plasma). In 62 samples of urine, the selenium level, expressed as micrograms/g creatinine, was 11.4. The mean whole blood selenium concentration was significantly higher in men than women: 104.5 +/- 23.2 vs. 96.9 +/- 21.2 micrograms/1. No differences were found in red blood cells, plasma and urine between male and female subjects. A strong linear correlation was observed between red blood cell and whole blood selenium levels (r = 0.879; p less than 0.001) as well as between selenium levels in whole blood and plasma (r = 0.806; p less than 0.001). A weaker but still significant linear correlation was found between urine and whole blood as well as between urine and plasma selenium concentrations. The relatively low levels of the element in the blood and urine are probably due to its deficiency in the diet.
