Parvovirus B19 IgG EIA kit Part No. V519IGUS

Printed label inside the box lid of the Parvovirus has the incorrect Lot Specific Constant value

DiaSorin issued a customer notification letter on July 17, 2020. The letter states the following action to be taken: Please use the Lot Specific Constant value of 0.14 with your remaining inventory of Lot 71440040AA.. The Lot Specific Constant is used to calculate the cut-off value and use of the incorrect value may lead to: 1. An invalid test due to the Low Positive Control resulting above the upper limit of the assigned range. 2. The reporting of a false positive patient result if the Low Positive Control does not fail and invalidate the test run. If 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: 1. 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. 2. Take actions as appropriate. 3. 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. Complete page two of this letter and return to DiaSorin Inc. Forward this letter to anyone in your organization who may be impacted. We apologize for any inconvenience this may cause.
