First DNA-based blood test to help detect cystic fibrosis

The Food and Drug Administration (FDA) has approved the first DNA-based blood test to help detect cystic fibrosis. The Tag-It Cystic Fibrosis Kit directly analyzes human DNA to find genetic variations indicative of the disease. The test will be used to help diagnose cystic fibrosis in children and to identify adults who are "carriers" of the gene variations.

Modest triglyceride elevations linked to coronary artery disease risk

Even modest increases in blood levels of triglycerides, as well as a type of high cholesterol known as type III hyperlipidemia, are strongly associated with coronary artery disease in people with a family history of the disease, according to a new study in the April 5, 2005, issue of the Journal of the American College of Cardiology.
