What the company is doing
Siemens sent an Urgent Field Safety Notice letter dated December 2011 to all customers of the affected lots. The letter identified the product, description of problem, and actions to be taken by the user. Dade Actin FSL customers were instructed to exercise one of two options: 1) If customers would like to continue working with their Dade(R) Actin FSL reagent lot (if one of the impacted lots) they must verify on a regular basis (monthly) that their therapeutic range is still valid, e.g. by using a Heparin containing control. In the case that it is not valid, they are to adjust their existing therapeutic range or establish a new one. 2) If customers decide not to continue working with the Dade(R) Actin(R) reagent lot (if one of the impacted lots) they are to contact their Siemens representative at 1-800-242-3233, option 5, for a replacement lot. Once they have established a new normal, therapeutic, and quality control ranges, they are to discard the remainder of the old lot. Customers were advised to complete the response form included to confirm receipt of Safety Notice and fax back to (302) 631-8467. If you have any questions or concerns, please contact the Technical Solutions Center at 1-800-242-3233, option 1.
