Study Details

Study Description

Brief Summary

The aim of this research project, which is realised with the partnership of the enterprise Siamed'Xpress (Marseille), is to validate a new TSH diagnostic test in vitro, to allow an earlier screening of hypothyroidism. A serum bank will be conserved in the "Centre de Biologie Sud" ("Groupement Hospitalier Lyon Sud").

The serum samples will be assayed locally for the usual medical support to patients and after they will be sent to Siamed'Xpress (Marseille), where they will be assayed with the new diagnostic test. The results obtained from the two techniques will be compared.

The validation of this new TSH test represents a major advancement, since it could bring in the future to a therapeutic index which will allow clinicians to treat earlier asymptomatic patients with subclinical hypothyroidism.

Outcome Measures

Primary Outcome Measures

  1. TSH assay of all the patients samples conserved in the serum bank with two techniques: technique IRMA (Immuno Radiometric Assay) and the new technique developed by Siamed'Xpress (Marseille) [Recruitment period : 30 months (starting from February 2012) in order to establish a serum bank]

    Measurement of sensibility and specificity and determination of the cut-off value of the new TSH test proposed by Siamed'Xpress Study of the association between TSH measurements obtained with the different techniques (IRMA vs new technique proposed by Siamed'Xpress) Study of the concordance of the different diagnostic tests for hypothyroidism detection
