Summary derived from FDA notice
Reason for Recall
As stated by FDA
Updated and revised user instructions issued 7/14/22. Potential carryover issue may cause elevated quality control and sample results for heparin, apixaban or rivaroxaban when HemosIL Liquid Anti-Xa reagent is used in the same run with both HemosIL Liquid Antithrombin and HemosIL Q.F.A. Thrombin (Bovine), specific to instrument models that utilize a single reagent probe
Recommended Action
Per FDA guidance
*****UPDATE******PHASE 2 UPDATED - URGENT MEDICAL DEVICE CORRECTION This updated notification is intended to further clarify the Mandatory Customer Actions for the potential carryover issue identified on the following ACL TOP systems (previous URGENT MEDICAL DEVICE CORRECTION letter dated Feb 22, 2022), when running a specific reagent combination.
