Summary

There have been very few reports on rhythmic variation in thyroid hormone concentrations with a periodicity of 4-6 weeks. In an attempt to evaluate whether such a rhythm is a general phenomenon we studied ten healthy male students with weekly blood samples over 12 weeks for T4, T3 and TSH. No rhythmicity could be demonstrated.
