How accurate is the test?
Numerous studies have shown that CASC is highly reliable in ruling out obstructive Coronary Artery Disease. This means that if you test negative and are without symptoms, there is only a very small chance that you have Coronary Artery Disease. In addition, a June 1, 1996 press release from the American Heart Association stated that “Ultrafast CT scanning with an electron beam proved many times more powerful than the best available non-invasive test in predicting heart attacks and other coronary disease episodes, even in apparently healthy people.
Although these blood tests are highly reliable, no test is 100% accurate. The test cannot tell you when or whether you will develop colon cancer. Testing negative for an inherited colon cancer gene does not mean you will never get colon cancer. It means your risk of colon cancer is about the same as that of the average person. There are many different genetic mutations that can lead to FAP or HNPCC. Genetic testing does not find all of them. Because of this, a person may have a normal genetic test but still have an increased chance of having an inherited colon cancer.
