title: [An analysis on the reported values of trace elements in human serum].
abstract: Statistical analysis on the data of trace element contents in human serum, published in the past 30 years, indicated the reported values for the majority of trace elements tended to decrease, even by magnitude of two orders, with the rapid development in analytical techniques and the effective control of contamination of samples during their collection, treatment and analysis. While the reported values approached their true ones, they would change to follow a normal distribution from a log normal one, with relative standard deviation and geometric deviation diminishing and, arithmetic mean approaching geometric mean. On the basis of the above results, the author presents the normal values, the best estimated normal values and the best literature values for Cu, Zn, Se, Co, Mo, Mn, Cr, Ni, As, Rb, Br, Cs, and Al.
