Reason for Recall
The data reduction program written for a specific automated microtiter plate reader (Bio-Tek ELx800) was found to be faulty. This program is used to calculate the cut off values for the Diastat Anti-Thyroglobulin Kit assay. The negative Control Upper Limit should be less than 0.95, rather than less than 1.0.
Firm Action
Customers were sent a notification letter directing customers to check historical data for negative control results reading greater than 0.95 but less than 1.0. These results are invalid and patient results should not have been reported. Customers are instructed to verify negative control manually until new software version is installed. An effectiveness check form is requested to be returned.
