Lipid Profile, Non Fasting
Understanding Lipid Profile, Non Fasting
What is Lipid Profile, Non Fasting?
A lipid profile (non-fasting) is a group of tests used to measure the amount of cholesterol (fats) in your blood. This profile measures triglycerides, high-density lipoprotein (HDL) and low-density lipoprotein (LDL) cholesterol, non-HDL cholesterol, very low-density lipoprotein (VLDL), total cholesterol, LDL/HDL ratio and total cholesterol/HDL ratio. This profile helps to predict your risk for heart diseases such as heart attack or stroke. You may need this profile as a routine test to determine if your cholesterol levels are normal or if you have a family history of heart disease. A balanced diet, regular exercise, and an active lifestyle help maintain a healthy weight and lower the risk of heart disease.
Note: The Lipid Association of India (LAI) recommends both fasting and non-fasting lipid profile test for managing abnormally elevated cholesterol or fats (lipids) in the blood. However, a non-fasting lipid profile is required to determine the levels of triglyceride fats in the blood post meals.
What does Lipid Profile, Non Fasting measure?Contains 8 tests
Cholesterol - Total
A Cholesterol - Total test measures the total amount of cholesterol (fats) in your blood. Cholesterol is mainly synthesized in the liver and partially in the intestines. It acts as a building block for cell membranes, serves as a precursor to vital hormones, and helps in the production of bile acids that help digest fats. Cholesterol is transported through the blood by two kinds of proteins: low-density lipoprotein (LDL) and high-density lipoprotein (HDL). An optimal amount of these proteins is necessary for proper body functioning.

A Triglycerides test measures the amount of triglycerides in the blood and helps evaluate your risk of developing cardiovascular diseases. Triglycerides are a type of fat (lipid) that your body uses as a source of energy. When you consume more calories than your body needs, the excess calories are converted into triglycerides and stored in fat cells for later use. High triglyceride levels can contribute to the hardening and narrowing of arteries, increasing the risk of heart attack, stroke, and other related conditions.

Cholesterol - HDL
A Cholesterol - HDL test measures the concentration of high-density lipoprotein (HDL) cholesterol in the blood. HDL cholesterol plays a crucial role in maintaining cardiovascular health, as it helps transport excess low-density lipoprotein (LDL) cholesterol from the bloodstream back to the liver for excretion. This process prevents the buildup of plaque on the blood vessel walls, which can cause them to become narrow and less flexible. Higher levels of HDL cholesterol are generally associated with a lower risk of heart problems, such as heart attacks and strokes. By measuring HDL cholesterol levels, your doctor can assess your risk of developing cardiovascular diseases and can recommend appropriate preventive or treatment strategies, including lifestyle modifications and medications.

Cholesterol - LDL
A Cholesterol - LDL test measures the concentration of low-density lipoprotein (LDL) cholesterol in the blood. LDL cholesterol plays an important role in your body. It carries cholesterol from your liver to other parts of the body where it's needed for things like building cell walls and making hormones. However, it is often referred to as "bad" cholesterol because when present in excess in your blood, it can stick to your blood vessel walls leading to the formation of plaque, making them narrow and less flexible. When this happens, it's harder for the blood to flow, which can lead to heart problems, like heart attacks and strokes. By measuring LDL cholesterol levels, your doctor can assess your risk of developing cardiovascular diseases and can recommend appropriate preventive or treatment strategies.

Very Low Density Lipoprotein
A Very Low Density Lipoprotein test measures the concentration of very-low-density lipoprotein (VLDL) cholesterol in the blood. VLDL cholesterol plays a vital role in the body's metabolic processes. It is produced by the liver and is used to transport triglycerides, a type of fat, from the liver to various tissues throughout the body, where they are either utilized for energy or stored for later use. Though VLDL cholesterol is essential for the body's normal functioning, it is harmful if present in excess amounts. By measuring VLDL cholesterol levels, your doctor can assess your risk of developing cardiovascular diseases and recommend appropriate preventive or treatment strategies.

Total Cholesterol/HDL Cholesterol Ratio
An LDL/HDL Ratio test measures the ratio of low-density lipoproteins (LDL) to high-density lipoproteins (HDL) in your blood. These two types of lipoproteins carry cholesterol throughout the body. LDL, often referred to as the 'bad' cholesterol, carries cholesterol to the cells that need it. However, if there is too much LDL cholesterol in the blood, it can combine with other substances and form plaque in the arteries, leading to cardiovascular diseases. On the other hand, HDL, often referred to as the 'good' cholesterol, helps remove other forms of cholesterol, including LDL, from the bloodstream. It transports cholesterol back to the liver, where it is broken down and eliminated from the body, thus reducing the risk of cholesterol buildup and heart disease. The LDL/HDL ratio is a significant indicator of cardiovascular health. A high ratio indicates a higher amount of 'bad' cholesterol relative to 'good' cholesterol, implying a higher risk of developing heart disease. Conversely, a lower ratio implies a higher amount of 'good' cholesterol relative to 'bad' cholesterol, indicating a lower risk.

Non HDL Cholesterol
A Non HDL Cholesterol test looks for the “bad” cholesterol particles that are likely to contribute to heart problems. These bad particles include LDL (low-density lipoprotein) cholesterol, VLDL (very-low-density lipoprotein) cholesterol, and remnants of other cholesterol-carrying molecules. Cholesterol is a waxy substance that circulates in your bloodstream and is essential for various bodily functions. However, too much of “bad” types of cholesterol can build up in your arteries and increase the risk of heart conditions. LDL and VLDL cholesterol particles are often referred to as the "bad" cholesterol because they can stick to the walls of your arteries and form plaque, narrowing the arteries and restricting blood flow to your heart. By measuring non-HDL cholesterol, your doctor can assess your risk of heart disease and determine if any interventions or lifestyle changes are needed to protect your heart.
