If your cholesterol is being analyzed by a laboratory after a needle blood draw, you can expect to receive results within a few days. You may also receive results through an online health portal or in the mail. For point-of-care tests or at-home test kits with a device for analyzing cholesterol, results are available within minutes.

General reference ranges for total cholesterol are listed below:. Remember that total cholesterol alone does not offer a complete picture of your risk for cardiovascular problems. The amounts of good HDL and bad LDL cholesterol are important to consider, which is why these are evaluated as part of a complete lipid panel.

Cholesterol test results are also not the only factor determining your heart health. Your age, family history, and health habits are elements that affect your cardiovascular disease risk.

Using a risk calculator, your doctor may analyze your test scores alongside these other factors. Depending on your test scores and overall risk, treatment may be suggested to lower your cholesterol. Examples of treatment include lifestyle changes, such as increase to exercise, quitting smoking or changing your diet, as well as medications that help decrease cholesterol.

Your doctor can best discuss the benefits and risks of these approaches in your situation, but be sure to ask follow-up questions, such as:. While the main focus of cholesterol testing is on identifying cases of high cholesterol, it is also possible to have very low levels.

Cholesterol Tests Some types of cholesterol are considered good and some are considered bad. You may also have a lipid or coronary risk profile, which includes: Total cholesterol Low density lipoprotein LDL cholesterol High density lipoprotein HDL cholesterol Triglycerides another type of fat in your blood Very low density lipoprotein VLDL cholesterol Lipoproteins are made of fat and protein.

Your body makes cholesterol and uses it to do important things, like making hormones and digesting fatty foods. If you have too much cholesterol in your body, it can build up inside your blood vessels and make it hard for blood to flow through them. Over time, this can lead to heart disease.

Most people who have high cholesterol don't have any signs or symptoms. That's why it's so important to get your cholesterol checked. Your doctor will check your cholesterol levels with a blood test called a lipid profile. A nurse will take a small sample of blood from your finger or arm for this test.

There are other blood tests that can check cholesterol, but a lipid profile gives the most information. Total cholesterol is a measure of all the cholesterol in your blood. It's based on the LDL, HDL, and triglycerides numbers.

Having a high LDL level can increase your risk for heart disease. Having a low HDL cholesterol level can increase your risk for heart disease. Triglycerides are a type of fat in your blood that can increase your risk for heart attack and stroke.

The results of your lipid profile test may also show your non-HDL cholesterol number. Having a high non-HDL level can increase your risk for heart disease. As your LDL cholesterol gets higher, so does your risk of heart disease.

Take these steps to lower your cholesterol and reduce your risk of heart disease:. Find out what your cholesterol levels are. If your cholesterol is high or you're at risk for heart disease, take steps to control your cholesterol levels.

For example, you may need to fast not eat or drink anything except water for 9 to 12 hours before the test. You may also want to print these questions to ask your doctor about cholesterol and take them to your appointment.

Under the Affordable Care Act, insurance plans must cover cholesterol testing. Depending on your insurance plan, you may be able to get your cholesterol checked at no cost to you. Check with your insurance company to find out more. Medicare may also cover cholesterol testing at no cost. If you have Medicare, learn about Medicare coverage for cholesterol testing.

If you don't have insurance, you may still be able to get free or low-cost cholesterol testing. Find a health center near you and ask about cholesterol testing.

It's important to Kethods your cholesterol checked methosd. Too much cholesterol in testng blood can testingg a heart attack or a stroke. If Body volume scanner cholesterol is high, tessting can take Cholesterol level testing methods tezting lower it — like eating healthy, getting more physical activity, and taking medicine if your doctor recommends it. The general recommendation is to get your cholesterol checked every 4 to 6 years. Some people may need to get their cholesterol checked more often depending on their risk of heart disease. For example, high cholesterol can run in families. If someone in your family has high cholesterol or takes medicine to control cholesterol, you might need to get tested more often.

In some cases, cholesterol test results can be wrong. 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.

The CDC recommends regular testing every 4 to 6 years for most healthy adults. People with a family history of high cholesterol or other risk factors may need to get tested more often.

The CDC also recommends that children, adolescents, and young adults have their cholesterol levels checked once between the ages of 9 and 11, and again between 17 and If you do need to fast, you should avoid eating or drinking anything other than water for 9 to 12 hours before your test.

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. In some cases, it can also be performed during a regular doctor visit, at a local pharmacy, or even at home.

If you have health insurance, cholesterol tests that are ordered by your doctor will likely be fully or partially covered by your health insurance plan. 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. The reliability of home cholesterol tests can vary between brands. The reliability can also be affected by how well you follow the test instructions.

In a study , researchers found that two point-of-care lipid testing devices were relatively accurate and operated within the industry standards. This means that:. In a study , researchers analyzed the performance of five types of commercially available home cholesterol tests. The researchers found that the Roche Accutrend Plus test had an excellent performance, but that several of the other products had poor accuracy and diagnostic ability.

The researchers concluded that better regulation and standardization are needed for at-home cholesterol tests. For the most reliable results, laboratory testing may still be the best option, especially if you have risk factors for high cholesterol.

High cholesterol can be treated with lifestyle changes and medication. Lowering your LDL may help reduce your risk of heart conditions and other related issues. With this meal plan, only 7 percent of your daily calories should come from saturated fat. It also requires you to get less than mg of cholesterol from your food each day.

Some foods may help your digestive tract absorb less cholesterol. For example, your doctor may encourage you to eat more:. These medications help lower your LDL levels. Learn more about lowering your cholesterol here.

A cholesterol test can measure levels of cholesterol and fats in your blood to assess your risk of cardiovascular disease. Most healthy adults should get their cholesterol levels tested at least every 5 years.

People with a family history or at an increased risk of high cholesterol should get tested more often. If you do have high cholesterol, your doctor can work with you to create a treatment plan to get your cholesterol levels into a healthy range.

Treatment for high cholesterol usually consists of some combination of dietary changes, increased exercise, smoking cessation, and medication. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available.

VIEW ALL HISTORY. Your cholesterol can be tested without fasting. But for some,. You can get an HDL test to find out the level of good cholesterol in your blood. High cholesterol levels can stem from your diet, especially if you eat foods high in saturated fats, like red meat and butter.

Sometimes, though, your…. Here's what you need to know about fasting before a blood test, including how long to fast for and if you can drink coffee.

The cholesterol ratio is calculated by dividing total cholesterol by your HDL number. Discover what it means for your heart disease risk and how to….

Doctors usually recommend having high levels of HDL cholesterol, but in some rare cases HDL levels can be too high. Learn more. You probably hear a lot about high cholesterol, but can your cholesterol be too low? The short answer is, yes.

Nevertheless, some circumstances require patients to fast. Thus, the decision to fast or not to fast depends on the clinical question being asked by the respective physician, as outlined below:. Then, patients will undergo a venous blood sampling of 0.

The container for the specimen must be a gel-barrier transport, green-top heparin tube, or lavender-top EDTA tube. Then, the serum must be separated from other blood components within 45 minutes of collection.

Samples should be stored at room temperature. The LDL cholesterol estimation can proceed with two distinct methods; indirect and direct. The former approach utilizes the Friedewald cholesterol estimation formula.

On the other hand, the latter method utilizes homogeneous assays. Nonetheless, there were several limitations to direct methods.

A study of comparison between direct and indirect methods with the reference method of the ultracentrifugation in HIV patients, which hypertriglyceridemia are common, found that no adequate agreement between these two tests with the ultracentrifugation.

There are many major clinical practice guidelines set by several colleges and societies with their subtle differences between them.

However, the primary goals of these clinical practice guidelines are all the same, which are cholesterol testing to prevent CAD in healthy populations or primary prevention and to provide early detection and slow down the progression of diseases or secondary prevention.

Cholesterol screening is an integral part of primary and secondary prevention of ASCVD. It can detect a vulnerable population that may be asymptomatic but with a high risk of ASCVD due to genetic predispositions.

Additionally, it can detect cholesterol elevations secondary to other diseases, such as diabetes, chronic kidney disease, and HIV infection, or due to drug usage, such as oral contraceptive drugs and others.

Occasionally, when screening for cardiovascular disease by cholesterol test, the result might reveal low or even untraceable levels of LDL-C. However, three conditions preclude the use of this equation, explain as follows: [21].

Therefore, a new estimation method is proposed by Martin et al. Their estimation is more accurate because it does not use fix ratio between TG and VLDL, but it incorporates adjustable factors for the ratios of triglyceride and VLDL.

Consequently, when the LDL is very low, or the TG is very high, i. LDL-C and HDL-C levels are essential for calculating the year risk of ASCVD derived from the Lloyd-Jones et al.

Nonetheless, it can overestimate or underestimate the risk. Another risk-estimation tool identified as heart score, which is adopted by the European Society of Cardiology, also incorporates total cholesterol and HDL levels.

Specimen Collection Traditionally, when patients were scheduling for cholesterol testing, they needed to fast for more than eight hours. Thus, the decision to fast or not to fast depends on the clinical question being asked by the respective physician, as outlined below: Non- fasting blood lipid profiles are acceptable in several conditions, i.

Fasting blood lipid profiles are preferred or even mandatory in several conditions, i. Procedures The LDL cholesterol estimation can proceed with two distinct methods; indirect and direct. Indications There are many major clinical practice guidelines set by several colleges and societies with their subtle differences between them.

Patients with comorbidities that are likely to be benefitted from statins use, i. Risk stratification for patients without the disease, which might benefit from cholesterol-lowering treatment. Potential Diagnosis Cholesterol screening is an integral part of primary and secondary prevention of ASCVD.

However, three conditions preclude the use of this equation, explain as follows: [21] The first one is when there is chylomicron in the plasma. Chylomicrons contain triglycerides; thus, it can interfere with the formula for VLDL calculation, which is plasma TG divided by five. Fortunately, normal subjects do not have chylomicrons in their plasma.

Furthermore, chylomicrons can be present in the plasma of patients that suffer type I familial hyperchylomicronemia , type III familial dysbetalipoproteinemia , and type V combined hypertriglyceridemia.

The second one is in type III familial hypercholesterolemia FH. In this disorder, VLDL exists in two forms, which are the normal VLDL with the ratio of TG to cholesterol around five, and the unique VLDL which the cholesterol's content is abnormally higher with beta mobility on electrophoresis.

Friedewald et al. noticed that when they incorporate type IV FH patient cholesterol values, they notice outlier values and the decreased correlation coefficient between ultracentrifuge and estimated cholesterol measurement. Consequently, after they excluded these patients' values, the correlation coefficient rose.

Clinical Significance LDL-C and HDL-C levels are essential for calculating the year risk of ASCVD derived from the Lloyd-Jones et al.
