Summary derived from FDA notice
Reason for Recall
As stated by FDA
IMMAGE CRP Reagent lots M705441, M709279, & M709319, may demonstrate a prozone or hook effect on samples with extremely high CRP analyte concentration.
Recommended Action
Per FDA guidance
Customers were sent Urgent: Product Corrective Action letters dates, 1/22/2008. The letter identified the issue, discussed the impact, and listed the following actions/resolution. * To eliminate the hook effect when using these lots, run CRP samples beginning with the 1:216 dilution. ~ A limited correlation of patient samples run in the 1:36 dilution compared to the same samples run in the 1:216 dilution verifies acceptable performance (there may be a shift of up to 0.8 mg/dL for samples between 1.0 and 8.0 mg/dL). * Controls run in the 1:216 dilution may recover differently than those run in the default 1:36 dilution. A limited number of control samples were also run in the 1:216 dilution. * The IMMAGE 800 system can be set to default to a non-standard dilution for each chemistry. Change CRP to a Non-Standard Dilution of 1:216 in the Setup section of the software. Detailed instructions for configuring a Non-Standard dilution as default are located in chapter 5 of the IMMAGE 800 Immunochemistry System Operations Manual. * The IMMAGE system does not allow resetting the default dilution of a chemistry. Instructions for running CRP samples beginning in a Non-Standard Dilution are enclosed. * Complete and return the enclosed response form within 10 days so we may maintain our records. Customers are to share this information with their laboratory staff and retain this notification as part of their laboratory Quality System documentation. If you have forwarded any of the affected product listed above to another laboratory, please provide a copy of this letter to them. Questions regarding this letter should be directed to 800-854-3633 or customers can contact their local Beckman Coulter Representative
