You don’t need to be a clinical laboratory scientist to know that there is a connection between HDL- and LDL-cholesterol levels and cardiovascular risk. We are frequently confronted with these terms and the importance of reducing our “bad” cholesterol. Cholesterol screening is encouraged, but the traditional markers may fail to identify patients who are at high risk for cardiovascular disease. However, more accurate methods for determining risk are emerging. This course will acquaint you with several of these emerging cardiovascular risk markers that you may in the near future see added in your laboratory’s test menu.
