WASHINGTON (AP) - Health officials approved the nation's first skin test for cholesterol Monday, a system that detects the heart-clogging substance through the palm of the hand. The action approves its use only in certain already sick patients.
It's not for routine cholesterol screening, the Food and Drug Administration stressed. Drawing a little blood remains the only way to test the general population for high cholesterol.
