A cholesterol test is a blood test that measures the amount of cholesterol and triglycerides (a type of fat) in your blood. Cholesterol is a waxy, fat-like substance that's found in your blood and every cell of your body. Your body needs some cholesterol to make hormones , vitamin D , and substances that help you digest foods.

Indicadores
A small non-essential amino acid in humans, Alanine is one of the most widely used for protein construction and is involved in the metabolism of tryptophan and vitamin pyridoxine. Alanine is an important source of energy for muscles and central nervous system, strengthens the immune system, helps in the metabolism of sugars and organic acids, and displays a cholesterol-reducing effect in animals. (NCI04)
Indicadores
Apolipoprotein A-I (267 aa, ~31 kDa) is encoded by the human APOA1 gene. This protein is involved in the transport and metabolism of cholesterol.
Indicadores
An animal sterol found in the body tissues (and blood plasma) of vertebrates. It can be found in large concentrations within the liver, spinal cord, and brain. Cholesterol is an important component of the membranes of cells, providing stability. It is the major precursor for the synthesis of vitamin D, of the various steroid hormones, including cortisol, cortisone, and aldosterone in the adrenal glands, and of the sex hormones progesterone, estrogen, and testosterone. Cholesterol also has an important role for the brain synapses as well as in the immune system. In conditions featuring elevated low density lipoproteins (LDL), cholesterol often forms plaque deposits in the walls of arteries, a condition known as atherosclerosis, which is a major contributor to coronary heart disease and other forms of cardiovascular disease.
Pruebas
The determination of the ratio of total cholesterol compared to high-density lipoprotein type cholesterol present in a sample. The measurement may be expressed as a ratio or percentage.
Indicadores
A family of lipo-soluble steroids important to the absorption, metabolism, and function of calcium and phosphorus and the growth and development of bone and tooth enamel. Found naturally in animal tissues, cholecalciferol (vitamin D3) is formed in the skin when ultraviolet light activates cholesterol conversion into vitamin D3. Ultraviolet irradiation of ergosterol (plant vitamin D) forms ergocalciferol (vitamin D2). (NCI04)
Pruebas
The determination of the ratio of HDL cholesterol compared to LDL cholesterol present in a sample. The measurement may be expressed as a ratio or percentage.
Pruebas
The determination of the ratio of HDL cholesterol compared to total cholesterol present in a sample. The measurement may be expressed as a ratio or percentage.
Pruebas
The determination of the amount of HDL-cholesterol subclass 3 present in a sample.
Indicadores
The smallest and densest lipoproteins, containing a high proportion of protein. They are synthesized in the liver as empty proteins and they pick up cholesterol and increase in size as they circulate through the bloodstream. Because HDL can remove cholesterol from the arteries, and transport it back to the liver for excretion, they are seen as "good" lipoproteins.
Pruebas
The determination of the high density lipoprotein cholesterol and the low density lipoprotein cholesterol present in a sample.
