Limitations
"Estradiol levels tend to fluctuate dramatically during the perimenopausal transition.4 There is significant overlap of the expected range in menopausal women with values observed during normal menstrual cycles. Estradiol results obtained with different assay methods cannot be used interchangeably in serial testing. It is recommended that only one assay method be used consistently to monitor serial patient results.
