Reason for recall
The potential of out-of-range results and an underestimation of the free protein S level in normal patient plasmas. The defect only affects normal-range values.
Device recalls are issued when a component, software or design fault could cause the device to fail or give wrong readings. Many are corrections applied in the field rather than physical returns.
