  • Extra notes in the data
  • Reason
    Roche diagnostics has tested for fulvestrant interference / cross-reactivity with the elecsys estradiol assay; this investigation has shown that fulvestrant could potentially affect patient sample results. the reported issue may lead to falsely elevated results of estradiol. subsequently, misinterpretation of the hormone status could occur and the use of fulvestrant may be altered. in addition, the efficiency of anti-estrogen treatment might be underestimated.
  • Action
    Roche is advising customers that Fulvestrant will increase the apparent concentration of estradiol in women being treated with this drug. A review of estradiol assay results in patients taking fulvestrant is recommended. A disclaimer will be added to the “Interference – Limitations” section in the Method Sheet of the Elecsys Estradiol III assay: This action has been closed-out on 30/01/2017. “Due to the risk of cross reactivity, this assay should not be used when monitoring estradiol levels in patients being treated with Fulvestrant.”
