I was wondering what the functional range would be for B12 vs the VERY broad lab reference range. (thyroidpharmacist.com)
Some of the symptoms you might see with estradiol levels elevated above normal lab reference ranges (or sometimes even with «high normal» levels) are: fluid retention, mood swings, nipple sensitivity / breast tissue stimulation, bloating, hot flashes and, reduction in clinical benefit from TRT.

Most routine thyroid tests simply look at TSH using the standard lab reference range. (crossfitsanitas.com)
