Lipid profile tests are diagnostic examinations that assess the levels of cholesterol and triglycerides in the blood. Lipids are essential fats involved in various bodily functions, including energy storage, hormone production, and cell membrane structure. However, abnormal lipid levels can contribute to the development of cardiovascular diseases, such as heart attacks and strokes. Lipid profile tests help evaluate the risk of these conditions and provide insights into overall lipid metabolism. In this article, we will explore the significance of lipid profile tests, the components measured, and their applications in assessing cholesterol and triglyceride levels.
