New Gene Test Raises Questions
For decades now, home laboratory tests have been available for testing a variety of conditions, diseases and substances, with the advantages of privacy and convenience. More recently, genetic tests have appeared on the market, offered on the internet by commercial labs that sell kits used to collect a sample that is then sent to the laboratory for testing. The tests look for certain genetic information that may predispose one to certain conditions or diseases. Now, as reported in several national media outlets, a commercial lab has stirred some controversy with hopes to sell DNA collection kits directly to consumers through a national chain of drug stores. Experts are weighing in on both sides of the issue as to whether this is a positive or negative development for consumers, and the FDA is looking into whether it has oversight of such testing. Consumers interested in genetic testing should consider several questions: How reliable are genetic tests in general, and specifically, what is the value of the genetic information supplied by the test? What are the specific health benefits of the test? What, if any, are the downsides of genetic testing? Read more about the pros and cons of genetic testing.

Panel Suggests New Criteria for Gestational Diabetes
