HbA1c Calibrators LN 4P52-02 consists of: 4P52-02 Hemoglobin A1c 1 x 1.6 mL and 1 x 1.6 mL. A1c Calibrators (lyophilized) contain hemoglobin and glycated hemoglobin from human whole blood. Prior to lyophilization, the calibrator matrix is an MES-buffered solution. Preservative: Ofloxacin. For use in the calibration of the Hemoglobin A1c assay on the ARCHITECT c 8000 and c 4000 Systems.

HbA1c Calibrators LN 4P52-02, lot 45063UQ12 may contain a value sheet for a different HbA1c calibrator lot. If calibrator lot 45063UQ12 is used in the calibration of the HbA1c assay using values from an incorrect calibrator value sheet then all results, including quality control and patient, may be falsely elevated.

Product Correction letters dated April 30, 2014 were sent to all customers. The letters included isntructions for customers to: 1) verify that the lot numbr listed on each calibrator bottle agrees with the lot number printed on the value sheet; 2) If HbA1c Calibrators lot 45063UQ12 has already been utilized in your laboratory, verify the concentrations configured for this calibrator lot match the values in the letter; 3) If these do not match, use the values in the letter when calibrating the HbA1c assay using calibrator lot 45063UQ12; and, 4) follow your laboratory protocol regarding the need for reviewing previously reported patient results if incorrect calibrator values were used.
