Triglycerides, cholesterol, and other lipids are transported via the liver-produced lipoprotein known as VLDL (Very Low-Density Lipoprotein). Because elevated levels of VLDL can lead to the accumulation of plaque in the arteries, raising the risk of cardiovascular disease, it is regarded as a “bad” cholesterol. LDL (low-density lipoprotein) particles are smaller and less dense than VLDL particles. They go through metabolic alterations and become LDL in the end. Blood testing is a crucial tool for tracking low-density lipoprotein (VLDL) levels, which in turn helps determine cardiovascular risk and direct cholesterol-lowering treatment plans. The addition of “(HHD)” indicates the unique context or version of the exam, potentially referring to a specific medical facility or healthcare professional.
