What is a lipid profile?
A complete cholesterol test also known as a lipid panel or lipid profile test is a blood test which will help to know the quantity of cholesterol and triglycerides in your blood.
A lipid profile can help determine your risk of the buildup of fatty deposits (also called lipids) in your arteries which can cause narrowed or blocked arteries throughout your body (known as atherosclerosis).
The lipid profile test helps evaluate cardiovascular health by analyzing cholesterol within the blood. An excessive amount of cholesterol can build up within the blood vessels and arteries, damaging them and heightening the danger of a developing heart condition, stroke, and heart attack.
What are triglycerides?
Now, you know the lipid profile test is done to test the number of triglycerides in the blood, but what are triglycerides?
Triglycerides are actually lipid compounds made of glycerol consisting of three fatty acid chains of varying length and composition. These fatty acid chains are often saturated or unsaturated, and therefore the chemical composition of every chain is different. Each chain is made of carbon and hydrogen atoms with different single or double-bonded chains, as per the degree of saturation or unsaturation. Triglycerides are formed of very mixed types of chains, making the structural comparison very diverse in nature.
When should a lipid profile be checked?
The Lipid Profile Test can be prescribed by your doctor for several reasons:-
Screening: This is often routine testing to work out if your cholesterol is normal or falls into a borderline-, intermediate-, or high-risk category.
Monitoring: If you got irregular or abnormal results on previous tests or have other risk factors related to heart problems, lipid profile tests can help monitor the cholesterol in your blood.
Measuring response to treatment: If you've been advised to make lifestyle changes or prescribed cholesterol medications, your doctor will advise regular lipid profile tests to evaluate your response to the given treatment.
Diagnosis: Prescribing lipid profile tests can also be a part of the diagnosis of certain other medical conditions, for example, diseases that affect the liver. So, if your doctor notices symptoms that point to these diseases, they will prescribe a lipid profile test to diagnose the problem.
Which tests are included in the lipid profile?
The Lipid Profile test result consists of
HDL Cholesterol - High-Density Lipoprotein (HDL) cholesterol also known as the "good" cholesterol because it helps remove other sorts of bad cholesterol from your bloodstream. Higher levels of HDL cholesterol are related to a lower risk of heart problems.
LDL Cholesterol - Low-Density Lipoprotein cholesterol also referred to as the "bad" cholesterol can build up within the walls of your blood vessels and narrow the blood passage. A clot can form and get stuck within the narrowed space, causing an attack or stroke.
Total Cholesterol - Total cholesterol, as the name suggests, is the total amount of cholesterol in your blood. It includes LDL (LDL, or "bad") cholesterol and HDL (HDL, or "good") cholesterol.
Triglycerides - These types of fatty acid compounds, when in excess can lead to cardiovascular disease and pancreatic inflammation.
VLDL Cholesterol - Very-low-density lipoprotein cholesterol is made within the liver and released into the blood vessels to provide triglycerides to body tissues. VLDL cholesterol in high levels is linked to increases in the number of lipid deposits on the walls of arteries, which narrows the passage and restricts blood flow.
Chol / HDL Ratio - When the number of your total cholesterol is divided by the number of HDL cholesterol, the result is known as the cholesterol ratio. Higher the ratio, the higher the chances of developing heart disease.
What are normal cholesterol levels?
Cholesterol levels are measured in milligrams per deciliter (mg/dL) unit.
These are the healthy levels of cholesterol, based on age and gender:
For Age 19 or less:
Total Cholesterol
Less than 170mg/dL
Non-HDL
Less than 120mg/dL
LDL
Less than 100mg/dL
HDL
More than 45mg/dL
Men Aged 20 or more:
Total Cholesterol
125 to 200mg/dL
Non-HDL
Less than 130mg/dL
LDL
Less than 100mg/dL
HDL
40mg/dL or higher
Women aged 20 or more:
Total Cholesterol
125 to 200mg/dL
Non-HDL
Less than 130mg/dL
LDL
Less than 100mg/dL
HDL
50mg/dL or higher
Symptoms of high cholesterol?
There are not usually any specific symptoms of high cholesterol which makes it all the more important to get checked. It is a hidden risk factor that suggests it happens without us knowing until it's too late.
Still, some people experience symptoms (but only when it's time to rush to the doctor) like
- Nausea
- Angina
- Chest pain
- Extreme fatigue
- Shortness of breath
- Pain in the jaw/neck/upper abdomen/ back
- Numbness or coldness in your extremities
People who smoke, have high blood pressure, are physically inactive, eat unhealthy food, are obese, have diabetes, or have a family history of premature coronary heart disease (before 55 for men and before 65 for women) are more at risk of high cholesterol levels.
Care required before and during the test
For laboratory lipid profile tests, you might have to fast for around 9-12 hours before your blood is taken, which means not eating anything and drinking nothing but water before the test.
In some cases, lipid profile tests can be conducted without fasting, but you ought to ask your doctor beforehand about the fast and always follow any pre-test instructions you're given.
One can reduce the risk by following a healthy low-salt diet that emphasizes fruits, vegetables and whole grains, staying physically active by exercising on most days of the week for at least 30 minutes, limiting the number of animal fats and consuming good fats in moderation, drinking less alcohol or better none at all, quitting smoking and maintaining a healthy weight.
