Total cholesterol refers to the sum of all cholesterol in the blood, including high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C). Normally, the total cholesterol level in adults should be between 2.83-5.20 mmol/L. High total cholesterol levels may increase the risk of cardiovascular diseases.
Also known as 'bad cholesterol,' because high levels of it can increase the risk of atherosclerosis and cardiovascular diseases. Normally, the LDL-C level should be below 3.4 mmol/L.
Also known as 'good cholesterol,' because it helps clear cholesterol from the blood, reducing the risk of cardiovascular diseases. Normally, the HDL-C level should be between 0.93-1.93 mmol/L.
Triglycerides are a type of fat in the blood that are transported along with cholesterol. The normal level of triglycerides should be between 0.45-1.69 mmol/L. High triglyceride levels are also associated with an increased risk of cardiovascular diseases.
If any of these four indicators exceed the normal range, it may be diagnosed as abnormal blood lipids.
