Reason
Tosoh Bioscience has become aware of potential degradation of HbA1c control lot # 7055 before the 60-days product stability claim. If degradation of these controls occurs, P00 peaks may be seen and the % HbA1c control values may drift higher than the assigned range. This may result in delays when performing routine instrument quality control. If this issue occurs, there may be a delay in testing and reporting patient test results. Tosoh has received two (2) complaints related to this issue with no serious injuries reported.
