Coronary Calcium Test

Updated March 21, 2022

This test uses a CAT scanner to measure the amount of calcium in the coronary (heard) blood vessels.  It has very good validity in predicting the degree of coronary artery disease (CAD, plaque). It can be a substitute in some cases for a stress test and/or angiography.

The only downsides is that the CAT scanner uses a good amount of radiation. Also the test is not covered by most insurances, costing ~ $200.
