A lipid panel is a blood test that measures the levels of different types of fats in the bloodstream. It typically includes measurements of cholesterol (both low-density lipoprotein, or LDL, and high-density lipoprotein, or HDL) and triglycerides. This test helps assess an individual's risk for heart disease and other cardiovascular conditions. Doctors often recommend a lipid panel as part of routine health check-ups, especially for those with risk factors like obesity, diabetes, or a family history of heart disease. The results can guide lifestyle changes or medication to improve heart health and reduce risks.
