High density lipoproteins (HDL) in a biochemical blood test

HDL-Cholesterol - High density lipoproteins (HDL) (sometimes written: HDL - High-density lipoproteins). Now cholesterol (line 6 of the analysis) was decided to be specified. Above it was written that the determination of the serum total cholesterol and triglyceride levels, as well as separate fractions of low density lipoprotein (of LDL - of low density lipoproteins ) and HDL (the HDL - high density lipoproteins) gives an indication of the degree of risk of coronary heart disease.     

Elevated levels of total cholesterol, low density lipoprotein (LDL) and triglycerides are regarded as a risk factor in the development of coronary heart disease, while an increase in serum high density lipoprotein (HDL), on the contrary, reduces the chances of progression of coronary disease.

Low and high density lipoproteins are composed primarily of cholesterol. Cholesterol in the HDL fraction is removed to the liver as it accumulates, where it is utilized and excreted into bile. That is why this fraction is considered "good cholesterol" - through it the blood can get rid of excess cholesterol. 

The cholesterol of the HDL fraction accounts for approximately 25–30% of the total serum cholesterol. In absolute terms, normal serum HDL is on average 30–60 mg / dL. We emphasize again that in coronary heart disease, an increase in serum high density lipoprotein (HDL) is regarded as favorable, and a decrease as an unfavorable sign. The ratio of HDL to total cholesterol is very important: if it is at the level of 18% or lower , it is a risk factor for coronary heart disease.   

The recommended level should be over 40 mg / dL.
