Test Code ESTRA ESTRADIOL

Important Note

Estradiol concentration in fulvestrant-treated women should only be measured using an assay that has negligible cross reactivity with fulvestrant such as Liquid Chromatography-Mass Spectrometry (LC-MS/MS) available at Mayo Clinic Laboratories (LAB2482). Estradiol requests on pediatric patients (<18 y) will be sent to Mayo (LAB2482), as they provide reference ranges based on Tanner Stage from age of 14 days-18 years.
