Tests
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.
Tests
A quantitative measurement of the amount of LDL cholesterol present in a sample of serum.
Tests
The determination of the ratio of the amount of intermediate density lipoprotein cholesterol compared to low density lipoprotein cholesterol present in a sample. The measurement may be expressed as a ratio or percentage.
Indicators
Low-density lipoprotein cholesterol — the primary lipid target in cardiovascular prevention.
Tests
The determination of the amount of oxidized low density lipoprotein cholesterol antibody in a biological specimen.
Indicators
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.
Indicators
A lipoprotein that carries cholesterol around the body, for use by various cells. LDL transports cholesterol to the arteries and increased levels are associated with atherosclerosis, and thus myocardial infarctions and strokes. This is why cholesterol inside LDL lipoproteins is called bad cholesterol.
Indicators
A water-soluble vitamin belonging to the vitamin B family, which occurs in many animal and plant tissues, with antihyperlipidemic activity. Niacin is converted to its active form niacinamide, which is a component of the coenzymes nicotinamide adenine dinucleotide (NAD) and its phosphate form, NADP. These coenzymes play an important role in tissue respiration and in glycogen, lipid, amino acid, protein, and purine metabolism. Although the exact mechanism of action by which niacin lowers cholesterol is not fully understood, it may act by inhibiting the synthesis of very low density lipoproteins (VLDL), inhibiting the release of free fatty acids from adipose tissue, increasing lipoprotein lipase activity, and reducing the hepatic synthesis of VLDL-C and LDL-C.
Indicators
Platelet-activating factor acetylhydrolase (441 aa, ~50 kDa) is encoded by the human PLA2G7 gene. This protein is involved in platelet-activating factor metabolism.
