A simple blood test to measure the level of triglycerides in the blood.
Triglycerides are the major form of fat stored by the body. Elevated triglyceride levels are considered to be a risk factor for atherosclerosis (hardening of the arteries) and coronary heart disease, because many of the triglyceride-containing lipoproteins that transport fat in the bloodstream also transport cholesterol, a known contributor to atherosclerosis.
Triglyceride levels are influenced by recent fat and alcohol intake, so you should fast from food for at least 12 hours and abstain from alcohol for at least 24 hours before being tested. Triglycerides are often measured as part of a lipoprotein panel or lipid panel in which cholesterol, HDL (high-density lipoprotein) and LDL (low-density lipoprotein) are also measured.
Mild to moderate triglyceride increases occur in many conditions, including alcohol abuse, obstruction of the bile ducts, and diabetes. High levels of triglycerides (greater than 200 mg/dl) are associated with a heightened risk of coronary heart disease. Markedly high triglyceride levels (greater than 500mg/dl) can cause inflammation of the pancreas (pancreatitis).

The major form of fat stored by the body. A triglyceride consists of three molecules of fatty acid combined with a molecule of the alcohol glycerol. Triglycerides serve as the backbone of many types of lipids (fats). Triglycerides come from the food we eat as well as from being produced by the body. Triglyceride levels […]
A hormone that is made by the thyroid gland. Triiodothyronine has three iodine molecules attached to its molecular structure. It is the most powerful thyroid hormone, and it affects almost every process in the body, including body temperature, growth, and heart rate. Also known as T3 and liothyronine.
In obstetrics, one of the three divisions of three months each during pregnancy, in which different phases of fetal development take place. The first trimester is a time of basic cell differentiation. The second trimester is a period of rapid growth and maturation of body systems. A second-trimester fetus that is born prematurely may be […]
a compound produced by bacteria in the stomach that appears to correlate with risk of heart disease, according to preliminary studies. TMAO is produced in the body from egg yolks and red meat. Researchers believe that it affects the body’s metabolism of cholesterol, leading to enhanced development of plaque on blood vessel walls, and can […]
- Trimethylaminuria (TMA)
An inborn error of metabolism associated with an offensive body odor, the smell of rotting fish, due to the excessive excretion of TMA in urine, sweat, and breath. Persons with TMA may experience tachycardia (fast heart rate) and severe hypertension (high blood pressure) after eating cheese (which contains tyramine) and after using nasal sprays containing […]
