New genetic test for Type 2 diabetes

November 19, 2008 12:00:00 AM PST
Several companies now offer genetic tests to determine whether someone has a gene for Type 2 diabetes. But they can cost up to $400. Are they worth it?Proponents of the tests say the results let people know their diabetes risk early, when it's still possible to reduce the odds through diet and exercise.

But researchers at MIT found that the tests weren't that helpful when it comes to that kind of prediction.

Instead, they say family history, age and blood work are a more accurate predictor of Type 2 diabetes.
