What is Cholesterol Test?
A complete cholesterol test is also called a lipid panel or lipid profile.Your doctor can use it to measure the amount of “good” and “bad” cholesterol and triglyceride, a type of fat, in your blood. Cholesterol is a soft, waxy fat that your body needs to function properly. However, too much cholesterol can lead to heart disease, stroke, atherosclerosis, a clogging or hardening of your arteries.

Who Is at Risk of High Cholesterol?
Cholesterol testing is very important if you:
1) Have a family history of high cholesterol or heart disease
2) Are overweight or obese
3) Drink alcohol frequently
4) Smoke cigarettes
5) Lead an inactive lifestyle
6) Have diabetes, kidney disease, poly cystic ovary syndrome, or an under active thyroid gland
All of above things can increase your risk of developing high cholesterol.


What Does a Cholesterol Test Measure?
A complete cholesterol test measures four types of lipids, or fats, in your blood:
Total cholesterol: This is the total amount of cholesterol in your blood.
Low-density lipoprotein (LDL) cholesterol: This is referred to as “bad” cholesterol. Too much of it raises your risk of heart attack, stroke, and atherosclerosis.
High-density lipoprotein (HDL) cholesterol: This is referred to as “good” cholesterol because it helps remove LDL cholesterol from your blood.
Triglyceride: When you eat, your body converts the calories it doesn’t need into triglyceride, which are stored in your fat cells. People who are overweight, diabetic, eat too many sweets, or drink too much alcohol can have high triglyceride levels.

Preparation for a Cholesterol Test
In some cases, your doctor may ask you to fast before having your cholesterol levels tested. If you’re only getting your HDL and total cholesterol levels checked, you may be able to eat beforehand. However, if you’re having a complete lipid profile done, you should avoid eating or drinking anything other than water for nine to 12 hours before your test.

Before your test, you should also tell your doctor about:
Any symptoms or health problems you’re experiencing
Your family history of heart health
All medications and supplements that you’re currently taking
If you’re taking medications that could increase your cholesterol levels, such as birth control pills, your doctor may ask you to stop taking them a few days before your test.


How Is a Cholesterol Test Performed?
To check your cholesterol levels, your doctor will need to get a sample of your blood.You will probably have your blood drawn in the morning, sometimes after fasting since the night before.
A blood test is an outpatient procedure. It takes only a few minutes and is relatively painless. It’s usually performed at a diagnostic lab. In some cases, it can also be performed during a regular doctor visit, at a local pharmacy, or even at home. Walk-in clinic rates can cost anywhere from INR 300 to INR 1000.Cholesterol testing at a local pharmacy can cost around INR 350. An at-home test can cost less. While tests that need to be shipped to a lab can cost more.

There are very few risks associated with having your blood drawn for a cholesterol test. You may feel slightly faint or have some soreness or pain at the site where your blood was drawn. There’s also a very slight risk of infection at the puncture site.

What Do the Test Results Mean?
Cholesterol levels are measured in milligrams (mg) of cholesterol per decilitre (dL) of blood. Ideal results for most adults are:
LDL: 70 to 130 mg/dL (the lower the number, the better)
HDL: more than 40 to 60 mg/dL (the higher the number, the better)
Total cholesterol: less than 200 mg/dL (the lower the number, the better)
Triglyceride: 10 to 150 mg/dL (the lower the number, the better)
If your cholesterol numbers are outside of the normal range, you may be at a higher risk of heart disease, stroke, and atherosclerosis. If your test results are abnormal, your doctor may order a blood glucose test to check for diabetes. Your doctor might also order a thyroid function test to determine if your thyroid is under active.

Can Test Results Be Wrong?
In some cases, cholesterol test results can be wrong. For example, a study published in the Journal of the American College of Cardiology found that one common method for calculating LDL cholesterol levels often produces inaccurate results.
Improper fasting, medications, human error, and a variety of other factors can cause your test to produce false-negative or false-positive results. Testing both your HDL and LDL levels typically produces more accurate results than checking your LDL alone.


Next Steps and Treatment
High cholesterol can be treated with lifestyle changes and medication. Lowering high levels of LDL in your blood can help you avoid problems with your heart and blood vessels.

To help lower your cholesterol levels:
Quit smoking tobacco and limit your alcohol consumption. Avoid high-fat and high-sodium foods, while maintaining a well-balanced diet. Eat a wide variety of vegetables, fruits, whole-grain products, low-fat dairy products, and lean sources of protein. Exercise regularly. Try to do 150 minutes of moderate intensity aerobic activity per week, as well as two sessions of muscle strengthening activities. Your doctor may put you on a “therapeutic lifestyle changes” or TLC diet. Under this meal plan, only 7 percent of your daily calories should come from saturated fat. It also requires you to get less than 200 mg of cholesterol from your food each day.
Some foods help your digestive tract absorb less cholesterol. For example, your doctor may encourage you to eat more.
Oats, barley, and other whole grains
Fruits such as apples, pears, bananas, and oranges
Vegetables such as eggplant and okra
Beans and legumes, such as kidney beans, chickpeas, and lentils
Obesity is also a common risk factor for high cholesterol and heart disease. Your doctor may encourage you to lose weight by cutting calories from your diet and exercising more.
Taking medications such as statins can also help keep your cholesterol in check. These medications help lower your LDL levels.
