What lipidogram shows

Atherosclerosis and diseases of the cardiovascular system are very dangerous conditions for humans. To assess the risk of their occurrence, you can use a blood test for lipid profile or lipid profile. Today’s article is devoted to what a lipidogram is in a blood test. This study carries very important information about the subject's health. It is recommended to donate blood for this test at least once every 5 years. In fact, this frequency is indicated for a healthy person. People with hereditary predispositions or risk factors for heart and vascular diseases should be tested more often.

Lipidogram, what is it?

Lipidogram is a complex of analyzes that determines the ratio of proteins and fats in the blood. The fact is that an excess of fat or cholesterol can be the reason for the appearance of fat deposits in the walls of blood vessels, which would entail a number of dangerous diseases.

Lipid profile includes an analysis of triglyceride levels, high and low and very low density lipoproteins( respectively, HDL, LDL, VLDL), total cholesterol( cholesterol or cholesterol).Also, the analysis of blood lipidogram includes the coefficient of atherogenicity, which is calculated by the above parameters. Consider all the lipid profile briefly separately. Each of them was devoted to a separate detailed article that you can find on our website.

Total cholesterol

Claiming that cholesterol is bad for the body is fundamentally wrong. Cholesterol( or cholesterol) is involved in the formation of cellular structure, hormones( including sex), in the production of bile acids, which are very important for normal digestion, etc. Cholesterol appears in the body as a result of production by the liver and with food.

By blood, cholesterol does not circulate in its pure form, because it does not dissolve in water. In the blood, you can see complex compounds, including cholesterol - lipoproteins. This implies the following indicator that is included in the lipidogram.

Lipoproteins

Above, we have already listed that lipoproteins are classified into three groups depending on density. Between themselves, they differ not only in density, but also in structure, function, and even impact on the vascular system.

  • Very low density lipoproteins

They have the largest diameter and the lowest protein content. In the body, they carry out the function of transporting lipids. Excess VLDL is more dangerous for the body, because the more significant the excess from the norm, the greater the risk of atherosclerosis can be diagnosed. In the blood, these compounds are hydrolyzed and transformed into low-density lipoproteins.

  • Low Density Lipoproteins

Conditionally called “bad” cholesterol. With an excess, they settle on the walls of blood vessels, creating the risk of narrowing of the lumen. It is especially important to know what a lipidogram shows for low density lipoproteins. This indicator is even more important than the level of total cholesterol in assessing the health of the heart and blood vessels. Changes in the level of LDL is most often associated with nutrition, physical activity and medications taken. Less often the deviation can be provoked by hereditary predisposition.

  • High-density lipoproteins

Conditionally called "good" cholesterol, because not only can they not linger in the walls of blood vessels, HDL also sends excess fat to further processing to the liver. Thus, their main function is to reduce the risk of atherosclerotic diseases. An excess of HDL is not dangerous. That is why the total cholesterol level is not as important for diagnosis as the amount of LDL and VLDL.The correct interpretation of the blood lipidogram determines the exact diagnosis and correctly prescribed treatment.

Triglycerides

These are esters of glycerol and fatty acids. They represent the body's energy supply, which is consumed immediately or “left for later” in the form of fatty deposits. For the most part, they are concentrated in various tissues, and are transported by blood as part of very low density lipoproteins. Increased triglyceride levels accompany diseases such as diabetes, hypertension, obesity, etc. Read more here.

It is very important to monitor the level of triglycerides and other indicators for overweight people, for this it is enough to donate blood for lipidogram.

Atherogenic Coefficient

This is a calculated figure that equals:

CA =( LDL + VLDL) / HDL /

The numerators indicate representatives of “bad” cholesterol, and the denominators indicate “good”.Accordingly, the more this coefficient exceeds the norm, the worse the condition of the cardiovascular system.

Pay attention to the article: "The rate and causes of deviation of atherogenicity."

Preparation for analysis

As well as other blood tests, this study involves some preparation:

  • No food intake 12 hours prior to analysis;
  • Lack of exercise and emotional stress half an hour before analysis;
  • Abstaining from smoking half an hour before the analysis;
  • Reception on the eve of the same food you are used to, but without especially fatty foods.

Blood is taken from a vein; in preparation for a lipid profile, it should also be borne in mind that taking certain medications, pregnancy, a long-term diet, or existing diseases may affect the result. Therefore it is important to report all these factors to the doctor when deciphering the analysis.

The rate of indicators in adults

Of course, in order to evaluate the blood indices obtained, it is necessary to know the rate for each of them. It is best to clarify these data in the laboratory in which you donated blood, because they may have minor errors due to the equipment. The optimal values ​​also depend on the gender and age of the patient. On average, the rate for each lipid profile is as follows:

  • CA: 2.1-3.6;
  • Triglycerides: & lt; 2.25 mmol / L;
  • Total cholesterol: & lt; 5.3 mmol / l;
  • HDL: 1.02-1.56 mmol / l;
  • LDL: & lt; 3.2 mmol / l;
  • VLDL: & lt; 1.62 mmol / L.
