The letter states the following action to be taken:\n\nPlease use the Lot Specific Constant value of 0.14 with your remaining inventory of Lot 71440040AA..\n\nThe Lot Specific Constant is used to calculate the cut-off value and use of the incorrect value may lead to:\n\n1. An invalid test due to the Low Positive Control resulting above the upper limit of the assigned range.\n\n2.  The reporting of a false positive patient result if the Low Positive Control does not fail and invalidate the test run.\n\nIf you have used the affected product Lot 71440040AA  in combination with the incorrect Lot Specific Constant of 0.10 and you obtained valid runs, please:\n\n1.  Review the test results of these valid runs for values between 1.1 Index and 1.54 Index, which may have been falsely reported as positive.\n\n2. Take actions as appropriate.\n\n3. DiaSorin recommends discussing the content of this letter with your laboratory director with respect to the need to review previous test results, conduct patient follow-up and/or repeat testing as appropriate.\n\nComplete page two of this letter and return to DiaSorin Inc.
