Experts Urge Caution on Genetic Testing

President Bush soon is expected to sign a bill that would ban the denial of insurance or employment based on genetic test results. Tests for single and multiple genes are expected to boom, the Associated Press (AP) reported May 5. But experts told AP there are other problems with testing. Some tests have not been proved useful, they said. A test may not help unless it can lead to a treatment or behavior change. U.S. government advisers recently called for more oversight of these tests.
