Total Cholesterol:- Total cholesterol - a measure of the total amount of cholesterol in your blood. It includes both low-density lipoprotein (LDL) cholesterol and high-density lipoprotein (HDL) cholesterol. LDL (bad) cholesterol - the main source of cholesterol buildup and blockage in the arteries. LDL;- LDL (low-density lipoprotein), sometimes called bad cholesterol, makes up most of your bodys cholesterol. High levels of LDL cholesterol raise your risk for heart disease and stroke. VLDL:-Very-low-density lipoprotein (VLDL) cholesterol is produced in the liver and released into the bloodstream to supply body tissues with a type of fat (triglycerides). There are several types of cholesterol, each made up of lipoproteins and fats. Triglycerides (TG):- A triglycerides test is a blood test that measures the amount of a fat in your blood called triglycerides. High triglycerides may increase your risk for a heart attack or stroke. A triglycerides test can help you decide if you need to take action to lower your risk. Your body uses triglycerides for energy.TC/HDL Ratio :-Your total-cholesterol-to-HDL ratio can be figured out by dividing your total cholesterol number by your HDL cholesterol number. Together, these numbers provide more information about your coronary heart disease risk than knowing only 1 of the numbers. In general: The higher the ratio, the higher the risk. LDL/ HDL Ratio:- LDL cholesterol moves cholesterol into your arteries. HDL cholesterol moves cholesterol out of your arteries. A high HDL cholesterol number lowers your risk for coronary heart disease. A high LDL cholesterol number raises your risk for coronary heart disease.
