[Evaluation of an immunoenzymatic method for determining TSH and establishment of reference values]

In the present work we reported the results of the valuation of IMx Ultrasensitive hTSH assay which is a Microparticle Enzyme ImmunoAssay (MEIA) for quantitative determination of human stimulating hormone (hTSH) in the human serum or plasma. We have determined the method's precision, within run and between run, sensitivity and recovery. This method has been compared with another one (Immuno RadioMetric Assay). Also reference values have been calculated in the "normal" male and female population and shortly commented.
