Comments
  • Testing is performed using the ARK Levetiracetam assay on the Siemens Atellica. 
  • This assay should not be used for patients taking Brivarecetam (BRIVIACT®) due to cross-reactivity. Serum levels of levetiracetam and/or brivaracetam should be confirmed by a valid chromatographic method if there is a possibility these drugs are co-present in circulation.
