Does anyone have an article they can link discussing the daily fluctuation in TSH values based on time of the day?

I have read here that we should get our blood drawn for TSH first thing in the morning, as TSH is highest then. Does anyone have an article they can link which discusses the daily fluctuation of TSH?

Thanks very much
