Does your TSH (thyroid) level change during the day? How much?

5 doctors agree

In brief: Yes

Tsh peaks around midnight and is higher in the early morning than in the afternoon.
In a normal person these changes are quite small and were not even detected until the 3rd generation TSH test became available.

In brief: No clinical issue

While there can be some mild fluctuation in TSH detected by sensitive assay, this is of no clinical significance to the patient over the course of a day.
