PDD outcome used in some sectors that indicates that testing was terminated before sufficient physiological information was collected. This may be due to the sudden onset of health problems, extreme emotional distress, or the examinee’s unwillingness or inability to remain for further testing. It may also signify that the examinee provided information after initial testing that necessitated subsequent testing, but it was not completed due to examinee fatigue, time limits, or equipment problems. A PDD decision of incomplete implies that testing may continue at a future date.
