Ldl Cholesterol Test Levels And Normal Range
LDL Cholesterol levels, if maintained at normal levels, can act as a friend as well as a foe. However, if these levels exceed the normal range, it can become a silent danger that increases the risk of heart attacks. Cholesterol exists in every cell in the body. It contains crucial natural functions. Although produced by the body, it can also be inhibited through food. This waxy and fat-like element is oil based and doesnt mix with the blood . Therefore, it is carried around the body in the blood by lipoproteins.
What Is The Difference Between Good And Bad Cholesterol
Cholesterol a waxy substance that builds in the arteries is not completely harmful, despite its reputation for being bad for you. In fact, some of it can even improve your health when consumed in the right amounts.
The physicians at the USC CardioVascular Thoracic Institute at Keck Medicine of USC can measure your good cholesterol and bad cholesterol levels, and help you adopt healthier eating and living habits so you can achieve the best balance of both.
Are Cholesterol Test Kits Reliable
The FDA does regulate some cholesterol tests, but not all. Reliability of kits can vary, and your results may not always be accurate. However, if you feel at-home cholesterol testing is preferable, ask your doctor to recommend a reliable kit. FDA approved home tests kits meet standards for accuracy.
Many test kits only provide total cholesterol levels, or information about HDL or triglycerides. Your LDL is not directly measured but can be calculated. You cant use cholesterol home tests to evaluate your overall heart risk yourself, as many risk factors â such as age, weight, gender, family history, and lifestyle â are used in this determination and should be performed by a doctor.

Why Cholesterol Affects Women Differently
In general, women have higher levels of HDL cholesterol than men because the female sex hormone estrogen seems to boost this good cholesterol. But, like so much else, everything changes at menopause. At this point, many women experience a change in their cholesterol levels total and LDL cholesterol rise and HDL cholesterol falls. This is why women who had favorable cholesterol values during their childbearing years might end up with elevated cholesterol later in life.

You will sit down and the phlebotomist will wrap a rubber band around your upper arm so that the vein in your elbow sticks out. Then they will use a needle to puncture the vein and remove blood. The blood is sent to the lab to be examined.
Youve probably been at health fairs where testing is offered. In that case, the person performing the test takes a drop of blood from your finger. The finger-stick test uses a small blade to poke a hole in the tip of your finger to get the blood.

- Diet: Saturated fat, trans fat and cholesterol in the food you eat increase cholesterol levels. Try to reduce the amount of saturated fat, trans fat and cholesterol in your diet. This will help lower your blood cholesterol level. Saturated and trans fat have the most impact on blood cholesterol.
- Weight: In addition to being a risk factor for heart disease, being overweight can also increase your triglycerides. Losing weight may help lower your triglyceride levels and raise your HDL.
- Exercise: Regular exercise can lower total cholesterol levels. Exercise has the most effect on lowering triglycerides and raising HDL. You should try to be physically active for 30 minutes on most days of the week.
- Age and sex: As we get older, cholesterol levels rise. Before menopause, women tend to have lower total cholesterol levels than men of the same age. After menopause, however, womens LDL levels tend to rise and HDL can drop.
- Heredity: Your genes partly determine how much cholesterol your body makes. High blood cholesterol can run in families.
What Is The Most Important Cholesterol Number

How Does Diet Affect Cholesterol Levels
Your cholesterol level has a lot to do with what foods you choose to put on your plate.
In the United States, Cardiovascular Disease is one of the leading causes of poor health, sometimes accompanied by death.
This happens to be directly associated with poor eating habits.
For instance, consuming too much fat can increase LDL cholesterol. Subsequently, elevating the risk of heart disease.
However, choosing a healthy diet reverses this process, giving you a clean bill on health.
And if these are not enough, there are other foods to sink your teeth into in order to balance your cholesterol level.
Here are some foods to increase HDL and decrease LDL levels.
What About Triglycerides
Triglycerides are another common source of fat found in the bloodstream, which provide a major source of energy. If you consume more energy from foods and beverages than what you need throughout the day, this energy is converted into triglycerides by the liver and stored within fat cells, ready for use later.
If you are consistently eating more energy than you burn, over time it is likely that you will have high triglycerides.
High triglycerides can lower levels of HDL and increase heart disease risk and have been linked to atherosclerosis and inflammation of the pancreas.
The good news is that you can lower your triglycerides rapidly through dietary changes.

What Do Hdl And Ldl Mean
LDL and HDL are the two main types of cholesterol that make up your total cholesterol.
- HDL , or good cholesterol, may protect the body against narrowing blood vessels
- LDL , or bad cholesterol, may make arterial narrowing worse
There is a third type of cholesterol called VLDL , which is another type of bad cholesterol produced in the liver, and contains a high amount of triglycerides.
Why Is High Cholesterol A Problem
Too much cholesterol in the bloodstream can harden arteries and promote fatty deposits within these arteries, potentially leading to dangerous blockages and narrowing over time called atherosclerosis.
If the blood vessels leading to your heart become too clogged, blood supply to your heart is reduced, which can lead to symptoms such as angina . If the artery becomes completely blocked, it can lead to a heart attack and stroke, which can be life threatening.
In 2017, the Australian Bureau of Statistics reported 43, 477 deaths in Australia from heart disease. This is approximately 30 per cent of all deaths in Australia, and most deaths are occurring in those aged 65 years and over.
However, heart disease takes years to develop, so you can take steps to reduce your risk.If you discover you have high cholesterol, have family members with high cholesterol, or are not sure if you’re at risk, it is advisable you seek your doctor’s advice.
Other risk factors for heart disease include increased age, ethnicity, family history, inactivity, smoking, high blood pressure, type 2 diabetes and obesity.If these risk factors are present in your life, it’s even more important to keep your blood cholesterol levels in check and seek your doctor’s advice.

An HDL cholesterol test and LDL cholesterol test measure different types of cholesterol. The two types of cholesterol are transported in the blood in distinct kinds of particles.
In common descriptions, HDL cholesterol is known as good cholesterol while LDL cholesterol is bad cholesterol. The amount of HDL cholesterol compared to LDL cholesterol can be an important consideration in cardiovascular health.
Measuring HDL cholesterol is more straightforward than measuring LDL cholesterol. For this reason, levels of LDL cholesterol are most often calculated using a formula based on levels of total cholesterol, HDL cholesterol, and triglycerides. In some situations, though, a doctor may prescribe a direct LDL test.

This can be done through diet and some lifestyle changes as well. These lifestyle changes can be adopted at any age.
Whats Your Cholesterol Level Anyway
A standard lipid blood test usually measures the concentration of total cholesterol, HDL cholesterol, and triglycerides levels. The LDL-cholesterol level is typically estimated from these numbers using a well-established formula that has been more recently revised and improved by researchers at Johns Hopkins.
So what are your target numbers? According to Michos, an ideal LDL cholesterol level should be less than 70 mg/dl, and a womans HDL cholesterol level ideally should be close to 50 mg/dl. Triglycerides should be less than 150 mg/dl. As Michos notes, total cholesterol levels well below 200 mg/dl are best.

Symptoms Of High Cholesterol
Often, there are no specific symptoms of high cholesterol. You could have high cholesterol and not know it.
If you have high cholesterol, your body may store the extra cholesterol in your arteries. These are blood vessels that carry blood from your heart to the rest of your body. A buildup of cholesterol in your arteries is known as plaque. Over time, plaque can become hard and make your arteries narrow. Large deposits of plaque can completely block an artery. Cholesterol plaques can also break apart, leading to formation of a blood clot that blocks the flow of blood.
A blocked artery to the heart can cause a heart attack. A blocked artery to your brain can cause a stroke.
Many people dont discover that they have high cholesterol until they suffer one of these life-threatening events. Some people find out through routine check-ups that include blood tests.
What Do Your Cholesterol Results Mean
When you have a cholesterol test, it is really important that your healthcare professional explains the results to you to prevent unnecessary worry and confusion.
Its not just your total cholesterol thats important and your results will include different types of cholesterol. If you are only given your total cholesterol, ask for a break-down of the other numbers. Its possible to have a healthy total cholesterol number but an unhealthy balance of the different types of cholesterol.
As a minimum, you should be given your total cholesterol and HDL numbers, then you can work out your ratio of total cholesterol to HDL cholesterol .
You might also have your triglycerides tested, these are another type of blood fat which are linked to heart disease.
Ask for a print out of your results if you are not able to speak to your GP, nurse or pharmacist.
Your results should include:
- Total cholesterol
This is sometimes written as ‘serum cholesterol’ or ‘TC’ and refers to your overall level of cholesterol.
- Non-HDL cholesterol
Your non-HDL cholesterol is your total cholesterol minus your HDL cholesterol. Its all the ‘bad’ cholesterol added together, including your LDL cholesterol. Ideally it should be as low as possible.
- HDL cholesterol
- TC:HDL ratio
You might be given a TC:HDL ratio, which is the ratio of HDL compared to the total cholesterol. If not, you can work it out from your HDL and total cholesterol numbers. This should be as low as possible. Above 6 is considered high.
