A lipid panel is a blood test that measures the levels of different types of fats in the bloodstream, primarily focusing on cholesterol and triglycerides. It typically includes measurements of low-density lipoprotein (LDL), often referred to as "bad" cholesterol, and high-density lipoprotein (HDL), known as "good" cholesterol. This test helps assess an individual's risk for heart disease and other cardiovascular conditions. Doctors usually recommend a lipid panel as part of routine health check-ups or if a patient has risk factors such as obesity, diabetes, or a family history of heart disease. The results can guide lifestyle changes or medication to improve heart health.
