Root cause

Action

Abbott sent a Product Correction letter dated 7/6/07, to all customers who received the affected product lot, informing them that the ARCHITECT Prolactin MasterChecks may not be stable at the recommended storage condition of 2 to 8 degrees Celsius (C) through expiration dating (15 months). Labeling is being permanently updated to indicate that ARCHITECT Prolactin MasterChecks are to be stored frozen until first use. After thawing, ARCHITECT Prolactin MasterChecks can be stored unopened at 2-8 degrees C for thirty days or until expiration which ever occurs first. All future shipments will contain updated storage and handling conditions of the ARCHITECT Prolactin MasterCheck. They were requested to check their inventory to see if they have any remaining inventory of lot number 82900M. If they know the date the lot was received or the date it was thawed, they may continue to use the ARCHITECT Prolactin MasterChecks if it has been stored at 2 to 8 degrees C unopened for less than 30 days. If the material has been stored at 2 to 8 degrees C for greater than 30 days or they do not know the number of days it has been thawed, they were instructed to discard the material. Reimbursement for discarded kits will be provided based on information provided in the Customer Reply form. Until labeling is updated, it will be necessary to use an alternate material for verification of sensitivity, calibration linearity, and the reportable range of the ARCHITECT Prolactin assay. They were requested to forward a copy of the letter to any laboratory to whom they may have forwarded the kits, and to retain a copy of the letter for their records. Any questions were directed to Abbott Customer Support at 1-877-4ABBOTT in the U.S. The accounts were requested to complete and fax back the customer reply form, acknowledging the receipt and understanding of the correction letter. Customers outside of the U.S., were requested to contact their local customer support representative.
