Abbott Laboratories MPG Recalls

ARCHITECT i System Assay CD-ROM, in vitro diagnostic analyzer, U.S. Version 21.0; for use on the ARCHITECT i System; Abbott Laboratories, Abbott Park, IL 60064; list number 06E58-21

The ARCHITECT AUSAB and ARCHITECT Anti-HCV assay parameter default interpretation screens when using ARCHITECT Assay CD-ROM US Version 06E58-21 does not align with the result interpretation options in the ARCHITECT AUSAB Reagent Package Insert (PI) 34-4162/R1 and ARCHITECT Anti-HCV PI 34-4152/R1.

On 1/2/07, Abbott sent Product Correction, Immediate Action Required letters dated 12/29/06 to all ARCHITECT AUSAB (list number 1L82-25) and ARCHITECT Anti-HCV customers (list number 1L79-25) who have the affected assay CD-ROM. The end users were informed that for the ARCHITECT AUSAB and ARCHITECT Anti-HCV assays, the default interpretations in the Assay Parameters window, installed from ARCHITECT I System Assay CD-ROM US Version 06E58-21, are not align with the result interpretation options in the package inserts. The accounts were advised to reconfigure the names of the interpretations in Assay Parameters window, following the steps in the enclosed attachments A and B. The accounts were requested to keep a copy of the letter on file until the revised Assay CD-ROM is received. The accounts were requested to complete the customer reply form, indicating that the letter was received, understood and disseminated to the laboratory manager/supervisor responsible for Architect AUSAB and/or Anti-HCV testing, and fax it to Abbott by 1/12/07.

ARCHITECT LH Reagent, each kit contains bottles of Anti-Beta LH coated Microparticles and bottles of Anti-Alpha LH acridinium-labeled Conjugate; list numbers 6C25-22 (4 x 100 tests), 6C25-27(1 x 100 tests), and 6C25-30 (4 x 500 tests); Abbott Laboratories, Abbott Park, IL 60064-3500

The lots of ARCHITECT LH Reagent List 6C25-22, have the potential to generate patient specimen results that are elevated. Correlation studies have demonstrated an upward shift in slope for patient results of approximately 13% on average when compared to other currently available reagent lots and an average bias from patient specimens of 13% to 17% has been observed.

Abbott initiated a field correction recall by letter dated 11/22/06 to all customers receiving the affected reagent. The accounts were informed of the elevated patient results with the affected lots of reagents. The accounts were requested to assess the inventory for the affected lots of reagents, discontinue use of the lots and destroy the remaining inventory of the lots, recording the number of kits on the customer reply form and faxing it to Abbott by 12/6/06, indicating that the letter was received and understood. Credit will be issued for the number of kits destroyed, as indicated on the reply sheet. Customers requiring additional information were directed to contact Abbott Customer Service at 1-877-422-2688.

ARCHITECT STAT Troponin-I Reagent; list numbers 2K41-20 (400 test kit), 2K41-25 (100 test kit) and 2K41-30 (2000 test kit); each kit contains bottles of microparticles, conjugate and assay diluent; Abbott Laboratories, Abbott Park, IL 60064

False Negative Results : The analytical sensitivity claim of less than or equal to 0.01 ng/mL (ug/L) might not be met for all lots of Architect STAT Troponin-I reagents, thus false negative results may occur with negative results less than 0.1 ng/mL

Abbott sent a Product Correction letter on 3/8/07 to all Troponin-I customers who received reagent lots in the last 12 months. The letters informed the accounts that the analytical sensitivity claim of = 0.01 ng/mL might not be met for all lots of Architect STAT Troponin-I reagents. The accounts were directed to evaluate the information the information provided in the letter against the reference range used in their laboratory to determine if any action needs to be taken; to follow their facility's policies and procedures for communicating with the heath care providers they serve; to forward a copy of the letter to any laboratory to whom they may have forwarded the reagent; 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. A follow-up press release was issued on 5/25/07 and a follow-up letter was issued on 5/29/07, providing updated instructions for laboratories to follow when using the product.

CA 15-3 Controls, list 9C08-10; an In Vitro diagnostic for use with the AxSYM or IMx CA 15-3 reagents, calibrators and instruments; each kit contains 2 bottles with 115D8:DF3 reactive determinants (human) prepared in TRIS buffer with protein (bovine) stabilizers to yield the following assay values (U/ml): Control L - 35 and Control H - 150; Abbott Laboratories, Abbott Park, IL 60064

The CA 15-3 Controls replicates out of range high resulting in invalid runs.

Abbott initiated a field correction recall by letter dated 6/9/06 and sent on 6/12/06 to all customers receiving the affected controls. The accounts were informed of the increase in invalid runs due to controls outside of the package insert range with this lot of CA 15-3 Controls.
