Advances in clinical genetic testing has led to increased insight into the human genome, including how challenging it is to interpret rare genetic variation. In some cases, the ability to detect genetic mutations exceeds the ability to understand their clinical impact, limiting the advantage of these technologies. Obstacles in genomic medicine are many and include: understanding the level of certainty/uncertainty behind pathogenicity determination, the numerous different variant interpretation-guidelines used by clinical laboratories, delivering the certain or uncertain result to the patient, helping patients evaluate medical decisions in light of uncertainty regarding the consequence of the findings...

Formerly defined "critical values", the importance of critical results (CRs) management in patient care has grown in recent years. According to the George Lundberg definition the result becomes "critical" when, exceeding actionable thresholds, it suggests imminent danger for the patient, unless appropriate therapy is initiated promptly. As required in most important accreditation standards, such as the ISO:15,189 or the Joint Commission standards, a quality reporting system should deliver the correct result to the appropriate clinician in a time-frame that ensures patient safety...
