Report Result Ref. Range Units Status Lab
ESTRADIOL 19 < OR = 39 pg/mL Normal Final TBR
Reference range established on post-pubertal patient
population. No pre-pubertal reference range established
using this assay. For any patients for whom low estradiol
levels are anticipated (e.g. males, pre-pubertal children,
and hypogonadal/post-menopausal females), the Quest
Diagnostics Nichols Institute Estradiol, Ultrasensitive,
LC/MS/MS assay is recommended (Order code 30289X).
Please note: patients being treated with the drug
fulvestrant (Faslodex(R)) have demonstrated significant
interference in immunoassay methods for estradiol
measurement. The cross reactivity could lead to falsely
elevated estradiol test results leading to an
inappropriate clinical assessment of estrogen status.
Quest Diagnostics order code 30289X-Estradiol,
Ultrasensitive LC/MS/MS demonstrates negligible cross
reactivity with fulvestrant.
