A lipid profile or lipid panel is a panel of blood tests used to find abnormalities in blood lipid ( such as cholesterol and triglycerides) concentrations. [not verified in body] The results of this test can identify certain genetic diseases and can determine approximate risks for cardiovascular disease, certain forms of pancreatitis, and other diseases.
The Liebermann–Burchard or acetic anhydride test is used for the detection of cholesterol. The formation of a green or green-blue colour after a few minutes is positive. Lieberman–Burchard is a reagent used in a colourimetric test to detect cholesterol, which gives a deep green colour. This colour begins as a purplish, pink colour and ...
In addition to plaque formation, LDL-C molecules can undergo oxidation. [1] Oxidation can cause further accumulation of cholesterol and the release of inflammatory cytokines, which damages the blood vessels. [1] [7] Due to the damaging effects of LDL-C, high levels increase the risk for cardiovascular disease and indicate dyslipidemia. [1]
A blood sample after 12-hours of fasting is taken by a healthcare professional from an arm vein to measure a lipid profile for a) total cholesterol, b) HDL cholesterol, c) LDL cholesterol, and d) triglycerides. [3] [105] Results may be expressed as "calculated", indicating a calculation of total cholesterol, HDL, and triglycerides. [3]
Hyperlipidemia is abnormally high levels of any or all lipids (e.g. fats, triglycerides, cholesterol, phospholipids) or lipoproteins in the blood. [2] The term hyperlipidemia refers to the laboratory finding itself and is also used as an umbrella term covering any of various acquired or genetic disorders that result in that finding. [3]
Blood lipids (or blood fats) are lipids in the blood, either free or bound to other molecules. They are mostly transported in a phospholipid capsule , and the type of protein embedded in this outer shell determines the fate of the particle and its influence on metabolism .
Chylomicron structure ApoA, ApoB, ApoC, ApoE (apolipoproteins); T (triacylglycerol); C (cholesterol); green (phospholipids). Chylomicrons transport lipids absorbed from the intestine to adipose, cardiac, and skeletal muscle tissue, where their triglyceride components are hydrolyzed by the activity of the lipoprotein lipase, allowing the released free fatty acids to be absorbed by the tissues.
Studies report that this comprehensive test is able to identify more than twice the number of patients with lipid abnormalities than the standard lipid panel (cholesterol and triglyceride test). The VAP test directly measures and routinely reports all five lipoprotein classes and sub-classes, including LDL, HDL, intermediate-density lipoprotein ...
