Biochemical blood test and Chol norms in tables and pictures

Blood test

Biochemical blood test helps with the control of metabolism. It is called the most informative analysis. As in any analysis, if the indicators bow to the side, this indicates a pathology. Chol in biochemical blood analysis is an important indicator of lipid metabolism.


  • Characteristics of cholesterol
  • Prerequisites for checking chol
  • Causes of Cholesterol Changes
  • The rules for blood donation for total cholesterol
  • Cholesterol
  • Increased chol level
  • Low cholesterol

This is a colorless liquid of the styrene group.

Chol is a part of:

  • cell structure, being an important part of the WLS,
  • sex hormones,
  • bile acid.
The total cholesterol is good (HDL), bad (LDL) and triglycerides. In the biochemistry of the blood, all are taken into account in the analysis.
Cholesterol indicators

Good cholesterol does not harm the body. It is not deposited in blood vessels, due to its high density, it transfers cholesterol from the cells to the liver (hence the abbreviation: high-density lipoprotein). Its level is not regulated by eating behavior. A high index (within the limits of the norm) of HDL indicates a good lipid metabolism - most of the fats are processed, a low chance of occurrence of atherosclerosis.

LDL, because of its low density, transfers cholesterol from the liver to cells (hence the abbreviation: low-density lipoprotein). However, there are cases when, due to its structure, LDL in the bloodstream breaks away from the "load". The latter forms plaques on the vessels, which prevent blood from moving along the bed of blood vessels. It can be increased or decreased by evading exercises and absorbing fatty foods or vice versa. Triglycerides enter the WLS and serve as a source of energy.

The delivery of blood for cholesterol is carried out in situations:

  1. Presence of atherosclerosis, hypothyroidism and hyperthyroidism, liver problems.
  2. Monitoring the effectiveness of the therapeutic diet.
  3. Preventive analysis.
  4. The presence of genetic and social prerequisites.

In addition to physical and hereditary predispositions to non-normative indicators of total blood cholesterol, taking medications based on steroids and related substances may be a problem caused by social factors:

  1. Wrong diet. The use of fatty foods in large quantities, alcohol abuse or malnutrition.
  2. Passive lifestyle.
  3. Independent (often incorrect) use of hormonal contraceptives.

The data obtained during the analysis are compared with the standard tables. The level of total cholesterol in the blood as a result of biochemistry is ready for the next day.

Blood sampling rules:

  1. Delivery of blood in the morning.
  2. Lack of exercise the day before blood donation.
  3. The lack of fatty foods and alcohol in the diet two days before the tests.
  4. Quitting smoking at least one hour before blood donation.
  5. The maximum restriction from stressful situations.
  6. 12 hours before the procedure, the exclusion of food.

If these rules are violated, the results of the analyzes are distorted and do not reflect the full picture of the study.

The observance of the rules of blood sampling depends on the end result

The concentration of total cholesterol is measured in millimoles per liter of blood.

Throughout life, cholesterol levels change. Differences are due to gender, which is associated with sex hormones.

In women, the total cholesterol index has a smooth rise - a straight line in the level change graphchol, if you draw it, it would be without sharp corners. Only for newborns this indicator has no gender differences.

Men do things differently. In connection with the lack of the function of procreation, their hormonal system does not undergo such changes with respect to sex hormones. Therefore, a rapid, albeit gradual rise in chol level indicators means an emerging pathology. Therefore, it is important for men in prophylactic purposes to take tests for biochemistry of blood every five years.

Age (years) Women (mmol / L) Men (mmol / L)
0 - 5 2.90 8 , 5 5
5 - 10 , 6 , 3 5
10 - 20 , 18 , 8 0
20 - 60 , 6 7 , 6 5
60 - ... , 5 5 , 2 6

Despite the data given in the table, the norm is not higher, mmol / l. LDL is not higher, in men and, in women, and HDL is not lower, 8 mmol / L in women and, 5 mmol / L in men.

When people talk about the dangers of high cholesterol, they mean bad cholesterol. It is the cause of the formation of plaques on the walls of the vessels, because of which the latter lose their elasticity, they clog the lumen of the vessel, preventing the blood from moving to the tissues. It can bring a fatal outcome (stroke, heart attack).

Hand increased cholesterol levels affect all aspects of human life.

Factors affecting cholesterol:

  1. The social factor. It:
  • lifestyle - sedentary, recumbent and other, associated with the restriction of movement;
  • food - eating a lot of high-calorie food, fatty, fried;
  • abuse of coffee;
  • stress.
  1. Physiological natural factor. This is the age and gender.
  2. Diseases. The main pathologies that affect the level of cholesterol include:
  • liver disease (hepatitis, cirrhosis, intoxications associated with liver destruction),
  • kidney,
  • pancreas (diabetes mellitus),
  • problems associated with the endocrine system that regulates sex hormones and lipid metabolism,
  • acute infections promote chol.
  1. Hereditary predisposition.

Factors that reduce elevated LDL:

  1. Changing the diet. Consultation with a nutritionist is advisable. Prevalence of cellulose, a decrease in the number of high-calorie and fatty foods. This includes maintaining optimal weight, sufficient water intake.
  2. Increased physical activity.
  3. Restoring the balance of hormones.
  4. Drug treatment.

It poses a danger due to a decrease in HDL (good chol). With its lowering, LDL will be greater, which will provoke atherosclerosis. However, lowering total cholesterol does not lead to good results, since it maintains muscle tone, promotes the assimilation of fat-soluble vitamins, participates in the synthesis of insulin, preserves the integrity neurons.

Hypocholesteria - a decrease in the normal level of cholesterol, caused by:

  • diets with a sharp weight loss,
  • diets consisting of low-calorie foods or products with missing fats,
  • frequent stress,
  • infections,
  • hyperthyroidism,
  • diseases of blood,
  • liver diseases,
  • hereditary predisposition.

This condition is fraught with:

  • Physiological factors: a decrease in the production of sex hormones, sexual activity up to infertility, weight problems, vitamin Vitamin A, D, E, K deficiency.
  • Pathological factors: hyperthyroidism, diabetes, stroke, osteoporosis
  • Mental factors: depression of different forms.

To regulate the condition and correct hypocholesteria, the same set of methods is used as in the treatment of excess cholesterol. This is a review of the diet, increased physical activity, reduced stress levels and medication. It is important to constantly monitor the level of chol, regularly donating blood for tests.
