LDL-C

Cholesterol is a waxy, fat-like substance that's found in your blood and every cell of your body. Your body needs some cholesterol to make hormones, vitamin D, and substances that help you digest foods.

A cholesterol test gives you and your health care provider important information about your risk of developing heart disease. If your test shows you have high cholesterol, you can take steps to lower it. This may decrease your risk of developing heart problems in the future.
