No fasting is needed for a cholesterol test. Fasting specimens have traditionally been used for the formal assessment of lipid status. Only water is permitted. Cholesterol is a substance found almost exclusively in animals. Body fluids including blood and all cells contain some cholesterol which is needed for good health. Cholesterol in blood is in complex particles called lipoproteins.
Cholesterol is a waxy, fat-like substance that’s found in your blood and every cell of your body. You need some cholesterol to keep your cells and organs healthy. Your liver makes all the cholesterol your body needs. But you can also get cholesterol from the foods you eat, especially meat, eggs, poultry, and dairy products. Foods that are high in dietary fat can also make your liver produce more cholesterol. There are two main types of cholesterol: low-density lipoprotein LDL, or “bad” cholesterol, and high-density lipoprotein HDL, or “good” cholesterol. A cholesterol test is a blood test that measures the amount of each type of cholesterol and certain fats in your blood. Too much LDL cholesterol in your blood may put you at risk for heart disease and other serious conditions.
The NHS health check is designed to spot the early signs of heart disease, stroke, kidney disease, diabetes and dementia. Learn more about triglycerides and what can raise them. Many health organizations recommend that all adults with no other risk factors for heart disease be tested with an LDL-C test as part of a fasting lipid panel every four to six years. It is the dedication of healthcare workers that will lead us through this crisis. Plaques can narrow or eventually block the opening of blood vessels, leading to hardening of the arteries atherosclerosis and increased risk of numerous health problems, including heart disease and stroke.
