How to test triglycerides?
The test is a simple blood test. The normal levels of triglyerides depend on the age and sex of the individual. For triglycerides testing, blood is drawn from a vein in the arm. A vein at the inside of the elbow or on the back of the hand is usually selected. The area where the needle will be inserted is cleaned with antiseptic. A small needle is inserted through the skin and into the vein, allowing a small amount of blood to flow into a collection tube or syringe. Once the blood is
collected, the needle is removed from the puncture site.
Before the blood test, the patient may be required to refrain from eating food for 8-12 hours. Patients should not drink alcohol for 24 hours before the test. Some drugs may affect the test and the patient may be asked to cease taking certain medications before the test. Oral contraceptives, estrogen, and cholestyramine (a drug used to treat high cholesterol) can increase triglyceride levels. Ascorbic acid (vitamin C), asparaginase (an enzyme), and various drugs used to treat high blood lipids, can decrease blood triglyceride levels. These substances should not be taken prior to this test.
After the blood sample has been taken and the needle withdrawn from the puncture site, a cotton ball or gauze pad may be placed over the site and direct pressure applied to reduce bleeding. A piece of surgical tape or gauze adhesive bandage strip may be secured over the site to prevent further bleeding.
The normal range of triglycerides in the blood depends on the age and gender of the patient. Women naturally have higher levels of triglycerides than men. Pregnancy can also increase triglyceride levels. As people age and gain weight, triglyceride levels generally increase. For adults, a normal level is considered to be less than 200 mg/dl (milligrams per deciliter). Levels from 200-400 mg/dL are considered borderline high.
Triglyceride levels ranging from 400-1000 mg/dL are considered high and levels greater than 1000 mg/dL are considered very high. High levels of triglycerides may indicate liver disease (cirrhosis), an under-active thyroid problem, uncontrolled diabetes, an infection of the pancreas (pancreatitis), kidney disease, or a diet too low in protein and too high in carbohydrates.
Extremely low triglycerides levels (less than 10 mg/dL) can also indicate a problem. Low levels may indicate malnutrition (not enough nutrients in the diet), malabsorption (inadequate absorption of nutrients in the intestinal tract), a diet too low in fat, or an over-active thyroid problem.
More information on cholesterol
What is cholesterol? - Cholesterol is a steroid lipid, found in the cell membranes of all body tissues, and transported in the blood plasma, of all animals.
What is LDL cholesterol? - Low-density lipoprotein (or "bad") cholesterol carries the largest amount of cholesterol in the blood and is responsible for depositing cholesterol in the artery walls. An elevated LDL cholesterol level is associated with a greater risk of heart disease.
Why is LDL cholesterol considered "bad"? - When too much LDL cholesterol circulates in the blood, it can slowly build up in the inner walls of the arteries that feed the heart and brain.
What is HDL cholesterol? - High-density lipoprotein (HDL) cholesterol is one of several types of fats and is measured as 'Total Cholesterol'. HDL is thought to pick up cholesterol from body tissues and bring it back to the liver for reprocessing or excretion.
Why is HDL cholesterol considered "good"? - Because HDL clears cholesterol out of the system and high levels of it are associated with a decreased risk of heart disease, HDL is often called "good" cholesterol.
How to raise HDL Cholesterol (good cholesterol)? - Regular aerobic exercise, loss of excess weight (fat), and cessation of cigarette smoking cigarettes will increase HDL cholesterol levels.
How cholesterol is measured and tested? - Cholesterol is measured in units called millimoles per litre of blood, usually shortened to "mmol/litre" or "mmol/l".
What're the cholesterol readings? - Cholesterol readings you receive from your medical provider generally include total cholesterol, LDL cholesterol, and high density lipoproteins cholesterol levels.
How often should my cholesterol be checked? - According to a new set of national guidelines governing cholesterol measurement and treatment, it is recommended that the level be treated every 5 years.
What causes high cholesterol? - High cholesterol is caused by eating a diet that is high in saturated fats and cholesterol. Some people, however, have an inherited disorder in which the body cannot properly metabolize cholesterol.
What are the high cholesterol risk factors? - A diet high in certain types of fats is one factor. Medical problems such as poorly controlled diabetes, an underactive thyroid gland, an overactive pituitary gland, liver disease or kidney failure also may cause high cholesterol levels.
What're the symptoms of high cholesterol? - People with severely elevated cholesterol may have fat deposits in tendons and skin, liver and spleen enlargement, and abdominal pain if pancreatitis develops.
What are triglycerides? - Triglycerides are another type of fat that is associated with adverse health consequences. Many patients with high cholesterol also have high triglycerides.
How to test triglycerides? - For triglycerides testing, blood is drawn from a vein in the arm. A vein at the inside of the elbow or on the back of the hand is usually selected.
How can LDL cholesterol levels be lowered? - Lowering low-density lipoprotein cholesterol involves losing excess weight, exercising regularly, and following a diet that is low in saturated fat and cholesterol.
How to reduce cholesterol with dietary therapy? - A low-fat, low-cholesterol diet is desired to keep your total fat consumption--saturated, polyunsaturated and monounsaturated--to fewer than 30 percent of your daily intake of calories.
What about when I go out to eat? - Avoid fried foods. Entrees covered with sauces, as well as creamy dressing, thick soups and casseroles should be avoided because they are usually rich in fat. Look for items labeled "heart-healthy" on the menu.
What cholesterol medications are available to lower cholesterol? - Cholesterol-reducing drugs include cholestyramine (Questran), colestipol (Colestid), gemfibrozil (Lopid), lovastatin (Mevacor), pravastatin (Pravachol) and simvastatin (Zocor).
What nutritional supplements are available to reduce cholesterol? - Artichoke is particularly helpful in relieving gastrointestinal problems that result from an inability to adequately process fats. Garlic assists the heart for centuries and has been used in herbal medicines for all manner of conditions.
What cholesterol lowering food are there? - Eating more fiber-rich foods may help to lower your blood cholesterol level. Soy products are also linked to reduced cholesterol because of their isoflavone content.
