Cholesterol-LDL stands for cholesterol-low density lipoprotein. An LDL is often referred to as bad cholesterol. Because high LDL results in a build-up of cholesterol in your arteries, which can lead to heart attacks and strokes.
If you have high levels of good cholesterol, called high-density lipoprotein (HDL), it might decrease your risk of developing heart disease. HDL helps to transport LDL cholesterol to your liver to be broken down, which helps avoid damage to your heart.
The other names are serum DLDL, and LDL-C test.
There is only one parameter.
A Cholesterol LDL test analyses the levels of cholesterol LDL in the blood. A low-density lipoprotein carries cholesterol in the blood. It mainly consists of cholesterol and similar substances, and a small amount of protein.
It is very important to monitor and maintain optimum levels of lipids to stay healthy. Intake of foods that are high in saturated fats and trans unsaturated fats may raise the levels of cholesterol in the blood. Extra cholesterol is deposited in plaques on the walls of blood vessels. It may result in atherosclerosis ( hardening of the arteries). It may also increase the risk of several other health problems, such as heart disease and stroke.
A Cholesterol-LDL test helps in determining the risk of heart disease in an individual. It also helps in planning out the treatment, considering known risk factors as well. Treatment might involve changes in lifestyle, such as diet and exercise, or lipid-lowering medications such as statins.
Reasons for LDL test:
It is done as a part of routine health checkups.
It is done as a part of the lipid profile along with cholesterol, triglycerides, and HDL.
It can diagnose cases of heart disease.
In cases of risk factors for heart disease like cigarette smoking, hypertension, diabetes mellitus, or a family history of heart disease.
It is done as a screening test for adults.
In case a person is taking lipid-lowering medication.
No special preparation is required. Fasting is required for this test.
What is the price of a LDL Cholesterol test?
This test requires a blood sample.
A healthcare provider, who is also called a phlebotomist, usually performs blood draws, including those for LDL cholesterol tests, but any healthcare provider trained in drawing blood can perform this task. Samples are sent to a lab where a medical laboratory scientist prepares the samples and performs the tests on analysers or manually.
You may expect to experience the following during the blood test or a blood draw:
You have to sit comfortably on the chair, and a healthcare provider will check your arms for an easily accessible vein. It is an inner part of your arm on the other side of your elbow.
Once the phlebotomist has located a vein, they will disinfect the area with an alcohol swab.
They will insert a needle into your vein to draw a blood sample. They may feel like a small pinch.
After they insert the needle, the required amount of blood is drawn into a test tube.
When they have drawn enough blood for the test, they’ll remove the needle and hold a cotton ball or gauze on the pricked site to stop any bleeding.
They apply a band-aid over the pricked site, and the blood collection is finished.
This process takes less than five minutes.
Once the phlebotomist has collected the blood sample, it will be sent to the laboratory for processing. When the reports are ready, your healthcare provider will share the results with you.
These blood tests are very common, and they don’t carry any significant risks. You can have a slight pain like an ant bite when the needle gets inserted, and a small bruise might develop there.
This report is available via email or WhatsApp within 6 hours after the collection of the blood sample.
Cholesterol - LDL values are most commonly analysed in milligrams per decilitre (mg/dL). Because high values of LDL may indicate a greater risk of heart disease and stroke, a low amount of LDL cholesterol is preferred. LDL values are categorised into the following segments:
LDL values are not interpreted alone, but rather as part of your overall health. Accordingly, cholesterol LDL results ranging between 70 mg/dL and 189 mg/dL can be considered high if you have diabetes, heart disease, a history of a stroke, poor circulation of blood to your legs, or other conditions.
Increasing physical activity, changing dietary habits, and medication might all be recommended to lower LDL cholesterol levels. Lowering LDL cholesterol might help to decrease your risk of heart disease, stroke, or other cardiovascular conditions.
What are normal LDL Cholesterol test results?
Normal ranges might vary slightly among different laboratories. Some of the labs use different measurements or may test different samples. Speak to the doctor about the meaning of your specific test results.

Frequently Asked Questions on LDL Cholesterol Test
When your body has high LDL cholesterol in your blood, it means the extra LDL cholesterol, along with other substances, forms plaque. This plaque builds up in your arteries and the condition is called atherosclerosis. As your blood vessels narrow, the narrowing blocks the blood flow to your heart and other organs.
Foods that increase the level of LDL cholesterol in the body include:
Red meat, such as beef, pork, and lamb are generally high in saturated fats.
Deep-fried fast foods
Processed meats or deli-style meats
Takeaways foods such as hamburgers and pizzas
Ghee, lard, and copha.
A chicken's eggs are an affordable source of protein and other nutrients. They are also naturally high in cholesterol. But the cholesterol in eggs does not seem to raise cholesterol levels the way some other foods, such as those high in trans fats and saturated fats do.
