HDL-C
Also written as: HDL-C — high-density lipoprotein cholesterol
High-density lipoprotein cholesterol, often called 'good cholesterol' due to its protective cardiovascular effects.
Full Definition
High-density lipoprotein cholesterol (HDL-C) is a measure of cholesterol carried by high-density lipoproteins in the blood. HDL particles transport cholesterol from peripheral tissues back to the liver for disposal, a process known as reverse cholesterol transport. Higher HDL-C levels are generally associated with lower cardiovascular risk, though recent studies have questioned whether raising HDL-C therapeutically provides cardiovascular benefits. Normal HDL-C levels are considered above 40 mg/dL in men and above 50 mg/dL in women.
Usage
Usage note: Always hyphenate. Use HDL-C rather than HDL when referring specifically to cholesterol content.
