What is HDL-C?

High-Density Lipoproteins are vehicles for transporting cholesterol in the bloodstream. HDL transfers cholesterol away from the vasculature and brings it to the liver, which is why it is referred to as “good cholesterol”.

Why is it included in the Cardiovascular Axis?

HDL-C levels provide another measurement of an individual’s risk of a cardiovascular event. While not as strong an indicator as apoB or LDL, HDL provides valuable context to your cardiovascular health.
