Table 3.
Sample results showing discrepant blood type results for the same patient (dates are approximate for privacy reasons). Adjacent rows are results from tests in the same test panel; shaded rows separate panels for the same patient; white rows separate data from different patients. Note that last two subjects show discrepancies within a single panel, resulting in aberrant blood type interpretations.
