Genetic
Testing
© Patricia Foote, December 2000
Genetic tests are available for more than 400 diseases, and
tests for more than 330 others are under development, according
to GeneTests, a Seattle-based genetic testing resource. More
than 175,000 genetic tests were performed in 1996 alone, the
last year for which estimates exist, reflecting three consecutive
years of 30 percent annual increases.
The public (and medical community too) needs to be informed
about the issues of genetic testing. A genetic test is different
from other medical tests in the following ways:
- The predictive nature of genetic testing. A positive result
indicates that that person is at increased risk for having a
specific disorder. It does NOT always mean that that person will
get that particular disorder.
- The private nature of the information.
- The ramifications for the person and for family members.
- The implications for reproductive decisions.
- The lack of knowledge about ways to influence/prevent certain
genetic outcomes.
- The relationship of the test results to self-perception.
Genetic testing should never be done without meeting with
a genetic counselor and the individual being tested must always
sign an informed consent document stating that he/she agrees
to the testing. Consumers should be sure they completely understand
the process and have given some thought to both a positive and
negative test result.
