Cholesterol is used to build cells and hormones, but if there is too much cholesterol, it accumulates in the arteries, forming Plaque, which increases the risk of heart disease and stroke. Cholesterol and Triglyceride Tests can help analyze blood, which examines the amount of total fat substances in the blood, such as cholesterol and triglycerides. Cholesterol moves through the blood and attaches to proteins, which are called Lipoprotein, through lipoprotein analysis. Lipoprotein Profile can measure the total amount of cholesterol, LDL cholesterol, HDL cholesterol and triglycerides in the blood. Please refer to the following information.

High-density Lipoprotein (HDL)

Adsorption of fat and removal of fat from the liver helps the body remove fat. HDL is also known as “good cholesterol” and has a lower risk of heart disease if there is more HDL in the body.

Low-density Lipoprotein (LDL)

Adsorbs a lot of fat and a little protein from the liver to other parts of the body. It is normal and healthy to have a certain amount of LDL in the body because some parts of the body require the cholesterol carried by LDL, but LDL is also called “bad cholesterol” because the body contains too much LDL, which can increase the risk of heart disease.

Very low-density Lipoprotein (VLDL)

There are very few proteins and their main function is to transport triglycerides from the liver. Excessive VLDL leads to cholesterol build-up in the arteries, increasing the risk of heart disease and stroke.


It’s a grease that the body uses to store energy, or to produce the energy needed by the muscles. If the amount of triglycerides and LDL is too high, the risk of heart disease is higher, then only LDL is too high.

Why do I need to test cholesterol and triglycerides?

It is generally recommended to do lipoprotein analysis every 5 years because lipoprotein  test analysis can detect the values of cholesterol and triglycerides mentioned above. If there is a problem of treating triglycerides, lipoprotein will more likely be done. Analysis allows physicians to monitor the efficacy. If you are suffering from diabetes, it is important to test for triglycerides regularly as the value of triglycerides will increase if the blood sugar is not well controlled.

In addition, children may have high cholesterol. Be careful to avoid having a heart disease or a family history that increases the risk of heart disease, such as diabetes, hypertension or overweight, it is recommended for Children to be screened. The screening age should be between 2 to 10 years old, under 2 years old is too young to be screened.

Before Testing

If you have diabetes and blood glucose is not controlled, the value of triglycerides may be high, and the amount of triglycerides will change dramatically due to meals, compared to fasting time, only a few hours after eating The amount of triglycerides is increased by 5 to 10 times, and the amount of triglycerides varies greatly every day. Therefore, it is normal to detect the number of triglycerides in fasting on different days.

Some drugs increase the amount of triglycerides in the blood. For example, Corticosteroids, Protease Inhibitors for HIV, Beta Blockers, and Estrogens.

At present, many scholars have begun to study the amount of triglycerides in those who are not fasting. This is because the blood lipid level on weekdays mainly reflects the level after meal rather than fasting level, so samples without fasting may be more representative of” The usual” triglycerides cycle level. However, it is not clear how to analyze the level of non-fasting to measure the risk, so it is recommended to ask your doctor if an empty stomach is required before taking a blood lipid test.

Inspection Process

What are you prepared in advance?

Depending on the test, there are different preparations:

If your doctor requires an empty stomach before the test, stop eating 9 to 12 hours before taking blood. You can only drink water. You can usually take the medicine with water in the morning of the test.
Do not eat fatty foods on the night before the test.
Do not drink alcohol or do intensive exercise before testing.

Many medications may affect your test results, so be sure to inform your doctor about any non-prescription drugs, prescription medicines, herbs or any natural substances you are taking. If you have done radioactivity within 1 week, such as: Thyroid gland or bone scan. If you have any concerns about the test, ask your doctor if you still need to do the test, assess the risk, process, results, etc.

What are the steps for the tests?

The process of taking blood is as follows:

The doctor will wrap the elastic band around the upper arm to block blood flow. As a result, the blood under the elastic band becomes larger, making it easier to pierce the needle into the blood vessels.
The doctor disinfect needles with alcohol.
The doctor will pierce the needle into the blood vessels, which may require more than one needle.
Attaching the tube to the needle and blood flows into the tube.
Once enough blood is pumped, the doctor will remove the elastic band from the arm.
After removing the needle, the doctor places gauze or cotton balls on the needle.
The doctor presses the gauze or cotton ball and then adheres to the bandage.

After Testing

Since the upper arm has an elastic band, it may feel a little tight, subject may not feel the  needle or feel a brief tingling sensation. The bandage and cotton can be removed after 20 to 30 minutes after the test, and the results can be booked with a physician. The physician will explain and analyze the results. Follow the doctor’s instructions. If you have concerns about glycerides testing, please consult your doctor for more information.

Results after the tests

The following are the basic categories of triglycerides, measured in mg/dl, with 1 dl equal to 100 ml:

General fasting: 150 mg/dL
High: 150 to 199 mg/dL
High: 200 to 499 mg/dL
Too high: greater than 500 mg/dL
Fasting values may vary from day to day. The value of triglycerides will change significantly after a meal and may be 5 to 10 times more than on an empty stomach. If the triglycerides on an empty stomach up to 1000 mg/dL, it may cause Pancreatitis should be treated as quickly as possible, reducing triglycerides. If the amount of triglycerides is high, cholesterol can also be high, which is called hyperlipidemia. Hypertriglyceridemia refers to the high level of triglycerides in the blood.

Definitions for cholesterol and triglycerides may vary from laboratory to hospital. Consult a physician if you have any questions about the test results.
