You've probably heard of "cholesterol"? Many of us talk about it, and sometimes we're even afraid of it. What exactly is cholesterol, are it good or bad for our bodies, and how do we know exactly about it? That's why doctors recommend a blood test called a "Lipid Panel." Today, we'll talk about it in detail and very simply.
What is this lipid panel?
Simply put, a lipid panel is a blood test that measures the amount of fat particles, or "lipids," in your blood. This test typically looks primarily at four types of cholesterol and another type of fat called triglycerides.
Think of our blood vessels as pipes that carry water. If the levels of lipids in our blood increase, just as dirt builds up inside the pipes, fats start to build up inside our arteries. What happens then? The blood vessels become clogged and narrow. This greatly increases the risk of developing serious diseases like heart disease, heart attack, and stroke .
That's why doctors use this lipid panel test for children and adults to assess your risk of developing heart disease. It is also called a lipid profile, lipid test, and cholesterol panel.
What are the 5 main things that a lipid panel looks at?
This test mainly looks at five types of lipids in your blood sample:
1. Low-density lipoprotein (LDL) cholesterol:
- This is what is called "bad cholesterol." Because if this LDL cholesterol increases, it gets deposited in the blood vessels and increases the risk of heart disease. It's like the garbage that accumulates in our house.
2. Very low-density lipoprotein (VLDL) cholesterol:
- This is another type of cholesterol. This VLDL is produced from the food we eat. If you donate blood after fasting, the amount is low. If it is high even after fasting, it may mean that your body is not controlling cholesterol properly.
3. High-density lipoprotein (HDL) cholesterol:
- This is what is called "good cholesterol." Do you know why? What this HDL cholesterol does is reduce the accumulation of bad LDL cholesterol in the blood vessels. It's like someone taking out the trash.
4. Total cholesterol:
- This refers to the total amount of all three types of cholesterol in your body: LDL, VLDL, and HDL.
5. Triglycerides:
- This is another type of fat that comes from the foods we eat. Elevated levels of triglycerides in the blood are linked to heart disease and a condition called pancreatic inflammation.
This is what is looked at in a typical lipid panel, but sometimes you can look at things in addition to this.
Why is this lipid panel test done?
Doctors use this test to analyze your blood cholesterol levels, assess the health of your heart and blood vessels, and help diagnose heart-related diseases.
There are several reasons why a doctor might ask you to do a lipid panel:
- As a general test: Find out if your cholesterol levels are at a healthy level or at a dangerous level.
- Monitor your cholesterol levels: If you have had abnormal results from a previous test, or if you have other risk factors for heart disease.
- See how you respond to medications: If you are taking medication to lower your cholesterol, see if the medication is working.
- Diagnose other diseases: This also helps in diagnosing some other medical conditions, such as liver disease.
Why do I need a Lipid Panel blood test?
There may be several reasons why you need this test.
If you have one or more risk factors for cardiovascular disease , your doctor may recommend that you regularly have a lipid panel to monitor your cholesterol levels. These risk factors include:
- If you are a man, you must be over 45 years old, and if you are a woman, you must be over 50 years old.
- If a previous test has shown high cholesterol.
- If you smoke cigarettes.
- If you are obese.
- If you don't exercise enough.
- If you have high blood pressure.
- If you have diabetes or prediabetes.
- If someone in your immediate family, such as your mother, father, or siblings, has had heart disease at a young age.
Imagine, our neighbor, Uncle Nimal, is in his 50s, a little overweight, and has diabetes. His doctor tells him to have a lipid panel at least once a year. That's because he's at high risk of developing heart disease.
Children may also need a lipid panel blood test. Children's cholesterol levels are related to three main factors: heredity, obesity, and diet. Often, children with high cholesterol have at least one parent who also has high cholesterol.
Also, doctors sometimes use a lipid panel to diagnose other medical conditions that can affect your lipid levels. For example:
- Pancreatitis
- Chronic kidney disease
- Hypothyroidism
What happens when you give blood for a test?
This is very simple. There is nothing to be afraid of.
1. You will be seated in a chair. Then the phlebotomist will look at your arms and find an easy vein to draw blood from. Most often, the blood is drawn from the inside of your arm, below the elbow.
2. After finding the vein, clean the area thoroughly and kill the germs.
3. Then a small needle is inserted into the vein and a blood sample is taken. At this point, you may feel like you are being bitten by a small ant.
4. After inserting the needle, a small amount of blood will collect in a test tube.
5. After the blood sample is collected, the needle is removed and a piece of cotton or gauze is placed and pressed to stop the bleeding.
6. It's like putting a plaster on and the job is done.
All of this takes less than five minutes.
Do I need to fast before the test?
In most cases, yes, you will need to fast for about 10 to 12 hours before having this lipid panel blood test. Fasting means not eating or drinking anything except water. However, in some special cases, this test can be done without fasting.
Therefore, the most important thing is to ask your doctor before the test whether you need to fast or not. Follow the doctor's instructions exactly. If the doctor tells you to fast, tell the doctor if you accidentally eat anything. Because not fasting can reduce the accuracy of the test results.
What's in the test report? What are the normal values?
After the blood sample is sent to the lab and tested, your doctor will tell you the results. A lipid panel report typically includes information like this:
- The name of the blood test, or what was measured in your blood.
- The number or measurement of your blood test result.
- That is the normal measurement range for the test.
- Is your result normal, abnormal, or high or low?
Here are the healthy levels (measured in milligrams per deciliter of blood – mg/dL) of the four main things typically looked at in a lipid panel:
- Total cholesterol: Less than 200 mg/dL.
- Good cholesterol (HDL cholesterol): more than 60 mg/dL.
- Bad cholesterol (LDL cholesterol): less than 100 mg/dL (less than 70 mg/dL for people with diabetes).
- Triglycerides: Less than 150 mg/dL.
If your results are above or below this target range, they can be classified as "borderline," "intermediate," or "high risk" for heart disease. In general, higher than normal levels of total cholesterol, LDL, and triglycerides, and lower than normal levels of HDL, increase your risk of heart disease.
It is very rare for cholesterol levels to be abnormally low. If they do occur, the cause is usually a medical condition that leads to malnutrition.
Should I be worried if the results are abnormal?
No. It doesn't necessarily mean you have a disease or need treatment.
The healthy cholesterol range for you depends on many factors. Your doctor will consider these things when analyzing your lipid panel results:
- your age.
- Overall health status.
- Medical history.
- Current medication.
- Other risk factors for heart disease.
Many doctors use these factors and a special risk calculator to determine whether you need further testing or treatment. If you have questions about the results, don't be afraid to talk to your doctor.
What to do next if abnormal results occur?
Because there are many factors that contribute to heart disease and everyone is different, there is no single way to treat abnormal levels of cholesterol and/or triglycerides.
If your lipid panel results are abnormal, your doctor may recommend one or more of the following:
- Continue to monitor lipid levels.
- Making changes to your daily lifestyle. For example, changing the foods you eat, exercising more.
- Starting cholesterol-lowering medication.
How often should this test be done?
Your doctor will tell you when you need a lipid panel. It mainly depends on whether you have any risk factors for heart disease. It also depends on your age and medical history. Even young children may need this test if they have any risk factors.
The best thing to do is to talk to your doctor, give him or her your complete health information, and see what he or she recommends.
Finally, things to remember
It's normal to feel scared when you see an abnormal test result. But remember, an abnormal lipid panel result doesn't necessarily mean you need treatment. Cholesterol and triglyceride levels have a big impact on your overall health, but many other factors affect your risk of heart disease.
Your doctor will consider many factors, including your health and past medical history, to decide what to do next. Together, the two of you will develop a plan that works best for you. So don't be afraid to talk to your doctor about anything.
So, I hope you now have a better understanding of what a lipid panel is. It is very important to be aware of these tests to stay healthy!
