The device defect is a positive bias of up to 20% relative to the currently marketed Roche device. In addition, the firm states that during the investigation they discovered that the cleared reference interval (RI) was not set optimally at product launch in 2010 and that the upper limit in the IFU of 53.5pg/mL is too low and should be closer to 80 pg/mL. They are in the process of submitting the data to support the revised RI in a new 510K submission and will be changing the IFU once the 510K is cleared.
