Are Home Cholesterol Testing Kits Accurate
The answer is yes if the tests are labeled CDC-certified. This means that the contents have been approved by the Cholesterol Reference Method Laboratory Network, a group that works with test makers, laboratories and the Centers for Disease Control and Prevention to make sure tests are accurate.
For home tests, you will still need to fast for 12 hours and to obtain blood for testing. Some kits come with packages for mailing to a lab for results. Other kits have a monitor so you can get the results at home. The cost of such home kits vary.
High Blood Cholesterol Levels
Cholesterol is a type of fat that circulates in your blood. Too much of it increases your risk of heart disease and stroke.
The condition doesn’t have any obvious symptoms so blood tests are required to confirm if a person has high blood cholesterol.
Changes to diet, regular exercise and other lifestyle changes can reduce cholesterol levels In some cases, people with persistent high blood cholesterol may be treated with cholesterol-lowering medication.
Firstly What Is Cholesterol
Cholesterol is an essential type of fat that’s carried in the blood.
All cells in the body need cholesterol it’s an essential part of cell walls in our bodies and has important roles, including to produce some hormones, maintain healthy nerve cells and in the synthesis of vitamin D.
Your body needs a small amount of cholesterol to function, but an imbalance between different types of cholesterol in the blood increases the risk of heart disease, one of the leading chronic diseases in Australia today.
About ¾ of the cholesterol in your body is made in the liver and a small amount may come from the food you eat. Various factors affect blood cholesterol levels including your diet and lifestyle, body weight and genes.

How Can I Lower My Cholesterol
There are two main ways to lower your cholesterol:
- Heart-healthy lifestyle changes, which include:
- Heart-healthy eating. A heart-healthy eating plan limits the amount of saturated and trans fats that you eat. Examples include the Therapeutic Lifestyle Changes diet and the DASH Eating Plan.
- Weight Management. If you are overweight, losing weight can help lower your LDL cholesterol.
- Physical Activity. Everyone should get regular physical activity .
- Managing stress. Research has shown that chronic stress can sometimes raise your LDL cholesterol and lower your HDL cholesterol.
- Quitting smoking.Quitting smoking can raise your HDL cholesterol. Since HDL helps to remove LDL cholesterol from your arteries, having more HDL can help to lower your LDL cholesterol.
- Drug Treatment. If lifestyle changes alone do not lower your cholesterol enough, you may also need to take medicines. There are several types of cholesterol medicines available, including statins. The medicines work in different ways and can have different side effects. Talk to your health care provider about which one is right for you. While you are taking medicines to lower your cholesterol, you should continue with the lifestyle changes.

What Is The Difference Between Good Cholesterol And Bad Cholesterol
Good cholesterol is known as high-density lipoprotein . It removes cholesterol from the bloodstream. Low-density lipoprotein is the bad cholesterol.
If your total cholesterol level is high because of a high LDL level, you may be at higher risk of heart disease or stroke. But, if your total cholesterol level is high only because of a high HDL level, youre probably not at higher risk.
Triglycerides are another type of fat in your blood. When you eat more calories than your body can use, it turns the extra calories into triglycerides.
Changing your lifestyle can improve your cholesterol levels, lower LDL and triglycerides, and raise HDL.
Your ideal cholesterol level will depend on your risk for heart disease.
- Total cholesterol level less than 200 is best, but it depends on your HDL and LDL levels.
- LDL cholesterol levels less than 130 is best, but this depends on your risk for heart disease.
- HDL cholesterol levels 60 or higher reduces your risk for heart disease.
- Triglycerides less than 150 milligrams per deciliter is best.

What Is Bad Cholesterol
Cholesterol moves in the body combined with proteins. This combination of cholesterol and proteins is called lipoproteins. The low-density lipoprotein or LDL cholesterol is called bad cholesterol. High levels of this cholesterol increase risk for heart diseases and stroke.
When you have high levels of LDL cholesterol in the body, the LDL cholesterol can accumulate on the walls of the blood vessels forming a plaque. The continuous cholesterol build-up or a plaque narrows the inside of the blood vessels with time. The narrowed blood vessel hampers the blood supply to the concerned organ. Thus, when the plaque is present in the heart, it can cause angina or a heart attack. Plaque build-up in the brain can cause a stroke.
Another type of cholesterol is HDL cholesterol. It is also called good cholesterol as it absorbs cholesterol and carries it back to the liver. The liver then removes the cholesterol from the body. HDL cholesterol, thus, can lower your risk for heart diseases and stroke.
What Reduces Cholesterol Quickly
There is no quick fix for reducing cholesterol. But there are plenty of ways to reduce your cholesterol naturally. Eating a high fiber diet, reducing saturated fat, weight loss , exercise, and smoking cessation are just some of the things within your control. If lifestyle interventions are unsuccessful, medication is always an option.

Normal Range For Cholesterol Levels
Cholesterol is measured in milligrams per deciliter . Below are the healthy levels of cholesterol, based on your gender and age:
Children age 19 and younger
The total cholesterol you want is less than 170mg/dL. You want less than 100mg/dL of LDL. You also want more than 45mg/dL of HDL. If your childs LDL cholesterol levels are higher than an adults, your doctor may prescribe a treatment plan and lifestyle change.
Women over 20
The total cholesterol women want ranges from 125 to 200mg/dL. Their LDL levels should be less than 100mg/dL. They should have 50mg/dL or higher of HDL.
Men over 20
A normal range for mens total cholesterol is 125 to 200mg/dL. Men will want less than 100mg/dL of LDL. You will also want 40mg/dL of HDL cholesterol.
Good Bad And Total Cholesterol: What Does It All Mean
If youve discussed cholesterol with your primary care physician, you know there are different types of cholesterol that affect your body in different ways. However, many people havent been educated about cholesterol. Is there really good cholesterol and bad cholesterol? What is a healthy cholesterol level, and how do you manage cholesterol? Heres some information to help you understand what cholesterol is all about.

How To Increase Your Hdl Cholesterol Levels
High levels of HDL cholesterol, often called good cholesterol, are associated with a reduced risk of coronary artery disease . It appears that HDL particles scour the walls of blood vessels, cleaning out excess cholesterol that otherwise might have been used to make the plaques that cause CAD. The HDL cholesterol is then carried to the liver, where it is processed into bile, and secreted into the intestines and out of the body.
So, the current theory goes, when we measure a persons HDL cholesterol level, we are measuring how vigorously his or her blood vessels are being scrubbed free of excess cholesterol.
How To Lower Cholesterol
If you have high cholesterol, your doctor may recommend lifestyle changes, medications or both.
Here are some ways to manage your cholesterol.
Eat heart-healthy food
What you eat can make a big difference to your cholesterol levels.
Cut back on foods high in saturated fats like:
- pies
- oily fish.
Drink less alcohol
Drinking too much alcohol can increase your LDL cholesterol and triglycerides. So drinking less is a good way to lower your cholesterol.
The Ministry of Health recommends no more than 10 standard drinks per week for women and no more than 15 for men. One standard drink is equal to:
- a standard can of 4% beer
- a small glass of wine
- a small single shot of spirits
If you have high cholesterol or you’ve been diagnosed with a heart condition, you may need to drink less than this.
Quit smoking
Smoking makes your LDL cholesterol stickier and reduces the amount of HDL cholesterol in your blood. It also damages the artery walls. This increases the build-up of plaque in your arteries and can cause risk of heart attack and stroke.
Quitting smoking is a great way to lower your cholesterol levels and reduce your risk of heart disease.
Move more
Sitting less and being more active are great ways to reduce high cholesterol.
This doesnt mean you have to join a gym or take up running it just means you need to move your body more throughout the day. Ideally you should do 30 minutes of activity a day.

Good And Bad Cholesterol
There’s only one kind of cholesterol but it is carried around the body by different carriers called lipoproteins, notably:
- Low density lipoprotein
- High density lipoprotein
In simple terms, cholesterol carried by LDLs is considered bad because when theres too much of it circulating in your blood it contributes to plaque build-up that clogs arteries and makes them less flexible . If you have high blood cholesterol your goal will be to reduce LDL levels in your blood.
On the other hand, cholesterol carried by HDLs is considered good because it carries cholesterol away from the arteries and back to the liver, where it is broken down and passed from the body. Any lifestyle changes or treatment for high blood cholesterol will aim to ensure HDL levels are increased or maintained at healthy levels.
When blood cholesterol tests are done, the level of triglycerides in your blood is also measured. Triglycerides are the most common type of fat that exists in food and in the body. When calories ingested in a meal are not used immediately by the body, they are converted to triglycerides and are transported to the fat cells to be stored. It is thought that elevated triglyceride levels may increase the risk of developing heart disease, particularly when associated with high LDL-cholesterol levels.
Healthy Cholesterol Numbers By Age
Its not just about how much HDL a person has. There are several other measurements clinicians use to assess a persons cholesterol and corresponding health risks.
Non-HDL levels are a persons total cholesterol minus their HDL level. This is not, however, equal to a persons LDL level. As mentioned, there are a few other types of cholesterol besides HDL and LDL. Though they play a more minor role in heart health, they are still important to measure when it comes to risk assessment. According to the Mayo Clinic, a non-HDL measurement appears to be a better risk predictor than simply measuring LDL levels.
Cholesterol is measured in milligrams per deciliter . The following are healthy cholesterol numbers by age for men and women, according to the U.S. National Library of Medicine:
Cholesterol Levels by Age Chart
|
Anyone age 19 and younger |
Men age 20 or older |
Women age 20 or older |
|
Total Cholesterol |
||
|
50 mg/dL or higher |
As you can see, the difference between healthy cholesterol levels for men and women over 20 years old comes down to HDL cholesterol: Women have a slightly higher range for healthy HDL.
Cholesterol levels do tend to increase as a person gets older. But healthy cholesterol levels remain the same.

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.
How Is The Total Cholesterol Or Blood Cholesterol Test Done
A blood test is a routine test. A phlebotomist is the person whose job it is to draw blood. Blood is usually drawn from the vein in your arm. 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.

What Does The Test Measure
An HDL cholesterol test analyzes a sample of blood to see how much cholesterol is present within high-density lipoprotein particles. Cholesterol is a waxy substance that is important for basic cell function. Cholesterol is transported through the body in the blood within lipoproteins, which are made up of fat and protein.
There are multiple kinds of lipoproteins that can carry cholesterol including high-density lipoproteins, low-density lipoproteins , and very low-density lipoproteins .
Cholesterol in LDL and VLDL particles can build up in the arteries and cause cardiovascular problems. In contrast, HDL particles transport cholesterol to the liver so that it can be eliminated from the body. Through this and other functions, HDL cholesterol helps protect against hardening and blockages of the arteries.
In practice, virtually all HDL cholesterol tests also measure total cholesterol, which is the sum of cholesterol found in all the different kinds of lipoproteins. By subtracting HDL cholesterol from total cholesterol, the doctor can determine the amount of non-HDL cholesterol that is present. In addition, tests like a lipid panel use a mathematical formula to calculate the amount of LDL cholesterol in your blood sample.

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.
can help you begin to assess your risk, but we strongly advise you discuss your risk with your GP as this tool does have limitations it doesn’t take your family history into account, for example.

Can You Get Rid Of Cholesterol Deposits
Researchers are working on ways to eliminate plaque from coronary arteries. One method that has been proposed involves using combinations of medicines in healthy people aged 25 to 55 years. It is suggested that getting the levels of cholesterol down very low will allow arteries to clear up and heal up.
Several researchers believe that the way to reverse heart disease, and to prevent it in the first place, is found in a whole food, plant-based diet. Studies have been done that have shown that limiting nutrition to whole foods that are plant-based have been successful in reducing blood cholesterol and even, in some cases, lessening plaque buildup.
What Are The Types Of Cholesterol
Cholesterol moves throughout the body carried by lipoproteins in the blood. These lipoproteins include:
- Low-density lipoprotein is one of the two main lipoproteins. LDL is often called the bad cholesterol.
- High-density lipoprotein is the other main lipoprotein. HDL is often called the good cholesterol.
- Very-low-density lipoproteins are particles in the blood that carry triglycerides.
