Terminated: 2012-01-29
Recalling firm: Leica Microsystems, Inc.
Product: Bond Ready-To-Use Primary Antibody Thyroid Transcription Factor-1 (SPT24); 7 mL vial; an in vitro diagnostic reagent for the qualitative identification by light microscopy of human thyroid transcription factor-1 in formalin-fixed, paraffin- embedded tissue by immunohistochemical staining using the automated Bond system; Leica Biosystems Newcastle Ltd., Balliol Business Park West, Benton Lane, Newcastle Upon Tyne NE12 8EW, United Kingdom; Catalog No.: PA0364
Product code: NJT Immunohistochemistry Reagents And Kits
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.
Root cause tag: design
FDA root cause: Device Design
Action: 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.

The FDA recall record names no cleared device, and no clearance has been matched to it.

About this record

Sourced from the FDA device recall database and the FDA enforcement reports, both ingested from openFDA. The recall record supplies the product, the reason and the product code; the enforcement report supplies the classification. The two datasets are exported by FDA on different days, and the date above is the older of the two, so nothing on this page is newer than it says.

MDM adds the root cause tag, derived from FDA’s own root cause text, and the cross-links to the product code, the clearances named on the record and MDM coverage. Where a recall has not been joined to an enforcement report, no classification is shown.
