Estradiol
Use
This estradiol assay is designed for the investigation of fertility of women of reproductive age and for the support of in vitro fertilization.
Special Instructions
Not provided.
Limitations
In children, postmenopausal women, and men, E2 levels are significantly lower than in reproductive-age women, warranting LC/MS-MS for greater sensitivity and specificity. Methods like ECLIA may not provide accurate measurements for these groups. Results from different assay techniques are not interchangeable. Interference from monoclonal mouse antibodies and certain drugs like fulvestrant may result in inaccurate results; consider sensitive methods like LC/MS-MS for these cases.
