Roche Estradiol III Assay Recalled Due to Fulvestrant Cross-Reactivity

Roche is recalling the Estradiol III assay because fulvestrant treatment causes falsely elevated estradiol results, potentially leading to incorrect patient management.

What this means for you

Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Our severity reasoning: The recall involves a risk-of-harm product (medical diagnostic) where the hazard is incorrect clinical management due to false results, but no specific injuries or illnesses are reported in the source text.

Plain-English summary

Roche Diagnostics Operations, Inc. is recalling the Elecsys Estradiol III assay (REF 06656021 190) used on Elecsys and cobas e analyzers. The recall involves 23,630 units distributed nationwide in the US, including Puerto Rico. All lot numbers are affected.

The recall is due to a recently identified cross-reactivity where the drug fulvestrant increases the apparent concentration of estradiol in women being treated with it. This can result in falsely elevated estradiol levels. The source text indicates that if treatment with fulvestrant has been altered or discontinued as a result of these falsely elevated results, the recall is necessary to prevent incorrect clinical decisions.

Customers should be informed that fulvestrant will increase the apparent concentration of estradiol. The assay should not be used when monitoring patients being treated with fulvestrant.
