Total cholesterol (TC): The normal range is 5.23-5.69 mmol/L. If it exceeds 5.72 mmol/L, it can be regarded as elevated blood lipids.
Triglyceride (TG): The normal range varies greatly, between 0.56-1.7 mmol/L. If it exceeds 1.7 mmol/L, it means elevated triglycerides, which is a risk factor for atherosclerosis and coronary heart disease. If it is lower than 0.56 mmol/L, it is called hypoTGemia.
The main components of blood lipids are triglycerides and cholesterol. Triglycerides are involved in energy metabolism in the human body, while cholesterol is mainly used to synthesize cell plasma membrane, steroid hormones and bile acids.
High-density lipoprotein cholesterol (HDL-C): The normal range is greater than 1.00 mmol/L. There are many influencing factors, such as age, gender, race, diet, obesity, drinking and smoking, exercise, drugs, etc.
Low-density lipoprotein cholesterol (LDL-C): The range is less than 3.12 mmol/L. The treatment target for LDL-C in patients with hyperlipidemia is below 2.6 mmol/L. Increased levels are common in familial hypercholesterolemia, type IIa hyperlipoproteinemia, etc.
Lipoprotein (a) [Lp(a)]: The concentration in the serum of healthy adults is less than 300 mg/L. Increased concentration can be seen in ischemic cardiovascular and cerebrovascular diseases, myocardial infarction, surgery, acute trauma and inflammation, nephrotic syndrome and uremia, malignant tumors except liver cancer, etc. Reduced concentrations may occur in liver disease, since lipoproteins are synthesized in the liver.

The dangers of high blood lipids:
Among the four indicators of blood lipid examination items, the one most closely related to cardiovascular disease is low-density lipids Protein cholesterol, also known as "bad cholesterol", accounts for about 60% of total cholesterol. In some cases, it can burrow into the arterial endothelium, form plaques, block blood vessels, and cause angina pectoris, cerebral infarction, and cholesterol embolism nephropathy.
Unstable plaques are like "time bombs" that "explode" and rupture under certain triggers, such as strenuous activity, emotional excitement, or smoking, forming acute thrombosis, leading to acute myocardial infarction, sudden death, etc. Research shows that without the involvement of "bad cholesterol," other risk factors are less likely to lead to atherosclerosis and subsequent serious disease.
However, the increase in "bad cholesterol" often has no symptoms, and many patients are still in the dark until they are admitted to the hospital due to illness.
