 Understanding about lipid blood test profile

Blood fat increases when bad cholesterol increases, reducing bad fat, affecting health, and increasing the risk of complications such as myocardial infarction, a cerebrovascular accident …

Blood fat test like? Blood lipid test (blood lipid test) includes tests aimed at checking the concentration of Cholesterol, LDL-C, Triglyceride HDL-C … in the blood, which are important for patients with heart disease. circuit.

Meaning Of Lipid Blood Indicators

What does a blood fat test include? After performing blood lipid tests, patients need to pay attention to 4 important indicators including Total cholesterol, Triglyceride, LDL-cholesterol (LDL-c), and HDL-cholesterol (HDL-c).

Through these indicators, your doctor will be able to evaluate dyslipidemia or other diseases related to the cholesterol index such as diabetes, atherosclerosis, heart disease.

What do cholesterol test results mean?

Specifically, the significance of the cholesterol test index is as follows:

Triglyceride test

Triglycerides are known to be a form of fat that makes up 95% of the fat in the daily diet. This is also one of the important components of animal fats and vegetable oils.

Therefore, by measuring triglycerides in the blood, doctors can assess the risk of patients with dyslipidemia as follows:

  • Triglyceride index <100 mg / dL (1.7 mmol / L): Triglyceride reading is normal.
  • Triglyceride index ranged from 150 – 199 mg / dL (1.7 – 200 mml / L): Triglyceride results were at a high boundary.
  • Triglyceride index ranged from 200 – 499 mg / dL (2 – 6 mmol / L): Triglyceride result was high.
  • Triglyceride index is higher than 500 mg / dL (6 mmol / L): Triglyceride result is very high.

Based on the results of this index, it is possible to assess the risk of diseases related to cardiovascular disease, diabetes if the patient has a high triglyceride index. From there, the doctor will give the most suitable treatment and advise the patient to change to a more scientific diet.

Get tested for total cholesterol

According to cardiologists recommended, all people aged 20 years and older should take the time to have periodic health checks, especially a total cholesterol test to promptly detect specific diseases as follows:

If the Total Cholesterol Index <200 mg / dL (5.1 mmol / L): The result is completely normal, the risk of coronary artery disease is very low.

If the total cholesterol index ranges from 200 – 239 mg / dL (5.1 – 6.2 mmol / L): This result shows that the patient has been having problems with health. To limit the risk of serious disease progression, it is necessary to focus on changing the lifestyle in a positive direction and should periodically monitor health.

A high total cholesterol indicates a very high risk of coronary artery disease

Total Cholesterol index from 240 mg / dL (6.2 mmol / L) or more: This result shows that the amount of cholesterol in the blood increases quite high. Accordingly, the risk of atherosclerosis is very likely to occur.

According to doctors, the older the person, the higher the amount of blood cholesterol will be. However, this was more common in males than females at the time both genders were under 50 years of age. But according to statistics show that the incidence of this disease in women is higher than that of men at the age of 50 and older.

LDL-cholesterol (LDL-c) test

LDL-cholesterol (LDL-c) test is often prescribed by doctors in case of patients with dyslipidemia, hypertension, atherosclerosis, diabetes, coronary artery disease …

  • Normal LDL-cholesterol: Less than 130 mg / dL (<3.3 mmol / L).
  • Threshold of harm to health when LDL-cholesterol: Higher than 160 mg / dL (> 4.1 mmol / L).
  • The higher the LDL-cholesterol result, the greater the patient's risk of atherosclerosis.

The typical cases when LDL-cholesterol increases such as obesity, atherosclerosis, dyslipidemia.

LDL-c reduction is common in cases such as malabsorption syndrome, hyperthyroidism, cirrhosis, depletion, etc.

When LDL levels rise too high in the blood, they will be deposited in the vessel walls of the heart and brain. If this condition persists, atherosclerosis will form.

These plaques are the cause of narrowing and clogging of the blood vessels, increasing the risk of sudden rupture of a cerebral vascular accident, life-threatening myocardial infarction.

Therefore, the LDL-c test is of great importance and should be closely monitored. The greater the number, the higher the risk. If it reaches the maximum level, it is extremely dangerous.

HDL-cholesterol (HDL-c) test

The HDL-cholesterol (HDL-c) test is usually ordered in the case of atherosclerosis, dyslipidemia, hypertension, or a test done to check your health periodically. people aged 40 and over.

  • Normal HDL-c: Coa more than 50 g / dL (> 1.3 mmol / L).
  • HDL-c index at the threshold of harm to health: Less than 40 mg / dL (<1 mmol / L).
  • An increase in HDL-c indicates a person has a lower risk of atherosclerosis.

When the HDL-c decreases: This is a warning sign that this person is at risk of atherosclerosis, often in the case of people with hypertension, dyslipidemia, angina pains appear. regularly…

How To Prepare For A Blood Lipid Test


Does a blood fat test need a diet? Doctors said, in order for the blood fat test results to not be affected, before that, the patient should not tolerate any food in the body for 8-12 hours.
