NCT03748407

Brief Summary

The objective of this study is to establish reference values in the general population from a Beckman Coulter DxI chemiluminescence assay. Indeed, the lack of harmonization of the methods of the dosage remains a major difficulty to optimize the management of patients with thyroid disease. This supplier has recently optimized its dosing kit according to the 3rd international standard of the WHO (IRB 81/565) for the TSH (Thyroid Stimulating Hormon). It is necessary to carry out a study of the distribution of the values of this TSH within our metropolitan population. The current data proposed by the supplier come from a study of a North American population. investigators propose to define usual values for thyroid status markers (TSH, FT4 \[free thyroxine\], FT3 \[free triiodothyroxine\]) from healthy EFS (French Blood Establishment) donors who meet the standard exclusion criteria for this type of study.

Outcome Measures

Primary Outcomes (3)

  • Determination of the usual values of TSH

    Determination of the usual values of TSH after assays on DxI automaton of the Beckman Company according to the standardization 3rd international standard (IRB 81/565)

    baseline

  • Determination of the usual values of FT4

    Determination of the usual values of FT4 after assays on DxI automaton of the Beckman Company according to the standardization 3rd international standard (IRB 81/565)

    baseline

  • Determination of the usual values of FT3

    baseline

Study Arms (1)

dosages in Healthy volunteers

OTHER

Only one arm : healthy volunteer blood donors. Performing a blood test for the determination of parameters that explore thyroid status : only once. Absence of other healthy volunteers group all healthy volunteers have a blood test performed in the same way.

Other: Dosages of Thyroid parameters

Interventions

Dosages of the following parameters: TSH, FT4 FT3, TGAb (Tyroglobulin antibody) , TPO Ab (ThyroPeroxydase Antibody)

dosages in Healthy volunteers
