This group of tests provides an overall assessment of an lipids. Lipids are a group of fats and fat-like substances that are important constituents of cells and sources of energy. A lipid panel measures the level of specific lipids in the blood.
Lipid panel includes:
- Total cholesterol – measures all the cholesterol in all the lipoprotein particles
- High-density lipoprotein cholesterol (HDL-C) – measures the cholesterol in HDL particles; often called “good cholesterol” because HDL-C takes up excess cholesterol and carries it to the liver for removal.
- Low-density lipoprotein cholesterol (LDL-C) – calculates or measures the cholesterol in LDL particles; often called “bad cholesterol” because it deposits excess cholesterol in walls of blood vessels, which can contribute to atherosclerosis. Usually, the amount of LDL-C is calculated using the results of total cholesterol, HDL-C, and triglycerides.
- Triglycerides – measures all the triglycerides in all the lipoprotein particles; most is in the very low-density lipoproteins (VLDL).
- Very low-density lipoprotein cholesterol (VLDL-C) – calculated from triglycerides/5; this formula is based on the typical composition of VLDL particles.
- Non-HDL-C – calculated from total cholesterol minus HDL-C
- Cholesterol/HDL ratio – calculated ratio of total cholesterol to HDL-C
