Posttest education and result notification

The primary component of the posttest session is result notification. An individual may change his or her mind about receiving results, however, until the moment of results disclosure. Therefore, one typically begins the disclosure session by confirming that test results are still desired. Some people may decline or delay receipt of test results. The percentage of people who will make this decision is unknown. Such people need ongoing follow-up and the opportunity to receive test results in the future.

Once confirmed, people appreciate direct, immediate reporting of the results; they often describe the wait for results as one of the most stressful aspects of undergoing testing.[88] Often, people need a few minutes of privacy to gather their composure after hearing their test results. Sometimes this precludes all but the briefest discussion at the initial posttest visit. Usually, individuals who have been properly prepared through the pretest counseling process do not exhibit disabling distress. Although it is rare that an acute psychological reaction will occur at disclosure, it is useful for providers of genetic test results to establish a relationship with a mental health provider who can be consulted should extreme reactions occur or who can be available by referral for people seeking further exploration of emotional issues.

Either at the time of disclosure or shortly thereafter, a session for the provider and the individual to consider the genetic, medical, psychological, and social ramifications of the test result is advisable. Despite having extensive pretest education, people may still be confused about the implications and meaning of the test results. Examples of frequently documented misconceptions include the belief that a positive result means that cancer is present or certain to develop; the belief that a negative result means that cancer will never occur; and failure to understand the uncertainty inherent in certain test results, as when only a limited mutation panel was examined. Regarding medical implications, it is important to inform the person of risk implications and management options for all of the cancer types associated with an inherited syndrome and to revisit options for risk management.

Posttest counseling may include consideration of the implications of the test results for other family members. It has been suggested that some individuals affected by an inherited disorder agree to have genetic testing performed in order to acquire information that could be shared with family members. There is evidence that implementation of a follow-up counseling program with the index patient, after test results are revealed, will significantly increase the proportion of relatives informed of their genetic risk. Follow-up counseling may include telephone conversations with the index patient verifying which family members have been contacted and an offer to assist with conveying information to family members.[89] Some experts have suggested that if a test result is positive, plans should be made at this time for the notification, education, and counseling of other relatives based on the test result of the individual. Written materials, brochures, or personal letters may aid people in informing the appropriate relatives about genetic risk.
