- “Good” is a type of lipoprotein particles that have a high density and protect vessels. They help in the prevention of diseases of the cardiovascular system.
- "Bad" is a type of lipoprotein particles that have a low density and are deposited on the walls of blood vessels. They are one of the main reasons for the development of atherosclerosis.
Often sent for analysis to identify the amount of total cholesterol in the blood, if it has shown poor results, then the content of each lipoprotein particle needs to be clarified. How to donate blood for cholesterol and what does the result depend on? When conducting this test, the patient's age must be taken into account, because in different life spans there are different indicators that are considered normal. So, for children, an acceptable concentration is 2.4 - 5.2 mmol / L. For adults - no more than 5.2 mmol / l.

Types of analyzes
Only a doctor can tell you how to donate blood for cholesterol and what kind of analysis is needed. Types of analyzes:
- General blood test - it is prescribed to determine the total number of particles in the body. The doctor prescribes such an analysis, after examining the patient and collecting an anamnesis.
