Comparison Between Calculated Bioavailable Testosterone Level With Radio-immunoassay Result.

No results posted yet for this study

Summary

Currently, the gold standard to obtain bioavailable testosterone results is radioimmunoassay (RIA). However, this assay requires specific equipment.

Giton in 2006 proposed an optimized calculation of the Vermeulen equation, the results of which seem to be well correlated with those obtained by RIA.

The aim of this study is to determine if the bioavailable testosterone levels determined by both methods are similar in order to replace the usual RIA assay of bioavailable testosterone by this calculation.
