What does the LDL Direct test evaluate?

The LDL Direct test specifically evaluates Low-Density Lipoprotein (LDL) cholesterol levels in the blood. LDL cholesterol is commonly referred to as "bad" cholesterol because high levels can lead to the build-up of plaque in the arteries, which increases the risk of cardiovascular diseases such as heart attack and stroke. The LDL Direct test provides a direct measurement of this type of cholesterol, enabling healthcare providers to assess an individual's risk for heart disease and make informed decisions regarding treatment or lifestyle changes.

Overall cholesterol levels refer to the total amount of cholesterol in the blood, which includes LDL, High-Density Lipoprotein (HDL), and other lipid components, but does not specifically target LDL levels. Similarly, the HDL test measures High-Density Lipoprotein levels, known as "good" cholesterol, which helps remove cholesterol from the arteries, while triglyceride levels are a different type of fat in the blood that can also influence heart health. Thus, only the LDL Direct test focuses specifically on the measurement of LDL cholesterol.
