Recall details

Recalling firm

Leica Microsystems, Inc.

Reason for recall

In combination with a sensitive polymer detection system, the TTF-1 antibodies may stain additional tumor types other than is currently indicated on the instructions for use.

Action taken

Leica Microsystems sent Medical Device Field Correction letters dated 7/28/10 to the affected customers via first class mail on the same date, informing them that in combination with a sensitive polymer detection system, the TTF-1 antibodies may stain additional tumor types other than is currently indicated on the Instructions for Use. Currently they state that lung and thyroid tumors may stain, but Leicas investigation further characterized the expression of the TTF-1 antigen and it may also be present in other tumors, e.g. thymomas. Customers who have received the affected lot numbers of the three products were requested to refer to the new Instructions for Use to review the amendments made to the Results Expected via the following links: http://bsd.leica-microsystems.com/pdfs/products/ttf-1-ce.pdf; http://bsd.leica-microsystems.com/pdfs/products/ttf-1-l-ce.pdf; and http://bsd.leica-microsystems.com/pdfs/products/pa0364.pdf; The accounts were asked to complete the attached Acknowledgement Form, acknowledging the receipt and understanding of the letter, listing the lot numbers of the units at their facility and fax it back to Leica at 1-847-607-3147. Additional questions should be addressed to the firm's office of Regulatory Affairs and Quality Assurance.
