However, unlike age and sex, this is a completely modifiable risk factor. Therefore, performing a blood lipid test when going to a general health check-up and controlling blood fat levels is a way to prevent diseases, ensure quality of life and prolong life in the future.
1. What is dyslipidemia?
Dyslipidemia is a condition in which plasma concentrations of cholesterol metabolites are higher than normal values. Along with hypertension, ischemic heart disease, diabetes, this is a fairly common chronic metabolic disorder, which increases the process of atherosclerosis, damages target organs such as the heart, brain, kidney.Indeed, many studies show that when there is hyperlipidemia, this is the main cause of increased atherosclerosis and coronary heart disease. At this point, treatment to lower cholesterol levels will significantly reduce the risk of cardiovascular events.
2. What are the blood lipid tests for the general physical examination?
Cholesterol is a blood lipid present in cell membranes and is a precursor to bile acids and steroid hormones. Cholesterol travels in the blood as separate particles containing both lipids and proteins (lipoproteins). Among the metabolic products of cholesterol, the two main types of lipoproteins found in serum are low-molecular-weight lipoproteins (LDL-C) and high-density lipoproteins (HDL-C).LDL-C makes up 60-70% of total serum cholesterol, contains a single apolipoprotein named apo B-100 (apo B). LDL-C is the major atherogenic lipoprotein and has been identified as the primary target in cholesterol-lowering therapy.
HDL-C accounts for 20-30% of total serum cholesterol. The main apolipoproteins of HDL-C are apo A-I and apo A-II. HDL-C levels are negatively correlated with the risk of coronary heart disease. Some evidence suggests that HDL-C has a protective role against atherosclerosis.

Precisely for the above reasons, in clinical practice, a physician's blood lipid test is a quantitative test of total cholesterol, HDL-C, LDL-C and triglyceride levels in standard units of millimol/Lit (mmol). /L) or milligrams/deciliter (mg/dL). However, some test devices can indirectly calculate LDL-C levels through existing parameters, using the following formula:
LDL-C = total cholesterol - HDL-C - triglycerides/2 ,2 (if values are in mmol/L) LDL-C = total cholesterol - HDL-C - triglycerides/5 (if values are in mg/dL)
3. Comment on blood lipid test results like?
Because blood lipid levels are related to meals, the ideal time to do this is when the patient has fasted for 12 hours, usually in the morning after waking up. Any blood draw or when the patient has eaten may result in pseudohyperlipidemia.Abnormal thresholds and disturbance levels for each index in blood lipid testing are presented in the following table:
