Estradiol (E2), Ultrasensitive, LC/MS:
Fasting Required: No
Lab: Quest Diagnostics
Specimen: Blood
Results: Average processing time 4-7 days
Note: Result turnaround times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
Special Instructions: Dietary supplements containing biotin may interfere in assays and may skew results to be either falsely high or falsely low. For patients receiving the recommended daily doses of biotin, draw samples at least 8 hours following the last biotin supplementation. For patients on mega-doses of biotin supplements, draw samples at least 72 hours following the last biotin supplementation.
Description: This sensitive estradiol assay is designed for the investigation of infertility, particularly in situations where low estradiol levels can be expected. The analytic range of the assay is appropriate for the assessment of the low levels of estradiol typically observed in men, prepubertal girls, and postmenopausal women. Estradiol is one of the primary components of Estrogen, the main female sex hormone. This test has an increased sensitivity over the normal Estradiol blood test. The increased sensitivity can be useful for situations where a person may have lower estradiol levels. The Sensitive Estradiol test is typically used for testing on children, adolescents, post menopausal women and men. This test may be used for children experiencing symptoms of early or delayed puberty. For post-menopausal women who are undergoing hormone therapy this test is typically more accurate that a regular estradiol test. Estradiol testing may be recommended for men with fertility issues or symptoms of a hormone imbalance. For men, results of a regular estradiol test may be interfered with by the presence of other hormones and steroids.
