[|AI|]  Hi, CT coronary Anglo is a very good test that accurately tell whether you have a blockage or not. If it does not show any blockage than it is certain you don't have a blockage. But if it shows blockage it does not reveal the exact percentage of blockage. To know that you need a coronary angiography which is an invasive procedure. So I strongly recommend you to go for invasive coronary angiography. Chat Doctor.
