Unsolicited information

Problems may arise where unsolicited information becomes
available. Non-paternity may be revealed either as a result of a
genetic test, or through discussion with another family member.
Where this would change the individual’s genetic risk, the
professional needs to consider whether to divulge this
information and to whom. In other situations a genetic test,
such as chromosomal analysis of an amniocentesis sample for
Down syndrome, may reveal an abnormality other than the one
being tested for. If this possibility is known before testing, it
should be explained to the person being tested.
