Who Should Get One And How Often

Everyone should get regular cholesterol checks, although the optimal frequency depends on age and certain health risk factors.

The American Heart Association recommends cholesterol testing for most adults every 46 years , starting at the age of 20 years. This testing will continue as long as they have a low risk of stroke or heart attack. After the age of 40 years, a doctor will calculate a persons risk and may suggest more frequent testing.

Some people have an increased risk of developing high cholesterol and may need additional testing. These individuals include:

  • people with a family history of heart disease or high cholesterol
  • anyone who had high cholesterol levels in a previous test
  • people with type 2 diabetes

lower LDL cholesterol levels than males on average, but their levels may increase after menopause.

Children should also undergo cholesterol tests. The Centers for Disease Control and Prevention recommend testing a childs cholesterol levels once at age 911 years and again between the ages of 17 and 21 years.

Cholesterol testing generally does not take place during puberty because hormones can alter the results of the test.

How Is A Total Cholesterol Test Different From A Direct Ldl Test

A total cholesterol test does not differentiate between good and bad cholesterol, but the bad LDL cholesterol plays an important role in determining cardiovascular disease risk.

In a standard lipid panel, LDL is calculated based on the levels of other fat molecules. However, in some cases, those calculations can be thrown off, especially if a person has high levels of triglycerides. A direct LDL test avoids the need for calculation by measuring LDL specifically.

  • Your family history
  • History of diabetes

Fasting And Cholesterol Tests

For many years, fasting prior to cholesterol tests was recommended in every case. However, increasingly, doctors are reconsidering this recommendation. Research suggests that food intake doesnt affect the accuracy of measurements for total cholesterol, HDL, and LDL.

That said, food before a test can elevate triglyceride levels, so accuracy there does require fasting. Prior to your test, double-check with your doctor about how best to prepare.

Cholesterol tests provide a broader glimpse of your health status. You cant really affect results without making significant, long-term dietary or lifestyle changes . As such, behaviors like steering clear of foods high in cholesterol or saturated fat within a couple of days of your lipid profile wont really affect results.

What Is A1c Testing

A1c test, also referred to as hemoglobin A1c, HbA1c, or glycohemoglobin provides information concerning average blood glucose levels during the past 3 months.

The A1C test is based on the attachment of glucose to hemoglobin, the protein in red blood cells that carries oxygen. Since red blood cells typically live for about 3 months, the A1c value represent a 3 month average. The A1C test result is reported as a percentage. A higher value indicates a higher amount of glucose within the blood stream.

    What Does The Test Result Mean

    In general, healthy lipid levels help to maintain a healthy heart and lower the risk of heart attack or stroke. A healthcare practitioner will take into consideration total cholesterol results and the other components of a lipid profile as well as other risk factors to help determine a person’s overall risk of heart disease, whether treatment is necessary and, if so, which treatment will best help to lower the person’s risk.

    In 2002, the National Cholesterol Education Program Adult Treatment Panel III provided the guidelines for evaluating lipid levels and determining treatment. However, in 2013, the ACC and AHA issued guidelines for adults that made recommendations on who should receive cholesterol-lowing therapy. .

    However, use of the updated guidelines remains controversial. Many still use the older guidelines from the NCEP ATP III to evaluate lipid levels and cardiovascular disease risk:

    For adults, in a routine setting where testing is done to screen for risk, the test results are grouped in three categories of risk:

    For children and adolescents:

    • A cholesterol below 170 mg/dL is acceptable.
    • A result of 170-199 mg/dL is borderline.
    • A total cholesterol reading greater than or equal to 200 mg/dL is considered high.

    For young adults:

    • A cholesterol below 190 mg/dL is acceptable.
    • A result of 190-224 mg/dL is borderline.
    • A total cholesterol greater than or equal to 225 mg/dL is considered high.

    When To Contact A Doctor

    Making sense of cholesterol tests

    People who receive a positive cholesterol test result should consider seeking medical advice. A doctor can help a person interpret their results and suggest the most suitable treatment plan.

    Doctors may recommend making lifestyle changes, such as getting more exercise, reaching or maintaining a moderate weight, and following a balanced diet.

    What Does A Cholesterol Test Measure

    A complete cholesterol test measures the levels of lipids, or fats, in your blood. It primarily measures your:

    • High-density lipoprotein cholesterol.HDL cholesterol is referred to as good cholesterol because it helps remove LDL cholesterol from your blood.
    • Low-density lipoprotein cholesterol.LDL cholesterol is referred to as bad cholesterol. Too much of it can cause cholesterol to build up on the walls of your arteries. This raises your risk of heart attack, stroke, and atherosclerosis.
    • Triglycerides. When you eat, your body breaks down fats in your food into smaller molecules called triglycerides. High levels of triglycerides in your blood increase your risk of developing cardiovascular disease. Having obesity or unmanaged diabetes, drinking too much alcohol, and eating a high calorie diet can all contribute to high triglyceride levels.
    • Very low-density lipoprotein . Your blood also contains another type of cholesterol linked to an

    In the United States, cholesterol and triglyceride levels are measured in milligrams of cholesterol per deciliter of blood.

    Can I Stay With My Child During A Lipid Panel

    Parents usually can stay with their child during a blood test. Encourage your child to relax and stay still because tensing muscles can make it harder to draw blood. Your child might want to look away when the needle is inserted and the blood is collected. Help your child to relax by taking slow deep breaths or singing a favorite song.

    Can Test Results Be Wrong

    In some cases, cholesterol test results can be wrong. For example, a recent study found that the assumption that VLDL levels are 20 percent of triglyceride levels is less accurate when triglyceride levels exceed 400 mg/dL

    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.

    Cholesterol testing is very important if you:

    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 21.

    Getting A Cholesterol Test

    What cholesterol is and what cholesterol blood tests show

    We recommend that all adults should get a cholesterol check, no matter what your age or how healthy you feel.

    High cholesterol doesn’t usually have any signs or symptoms, and it can be caused by your genes, so we advise getting a check even if you are young, fit and feel healthy.

    High cholesterol can lead to heart attacks and strokes. A cholesterol test, along with other simple tests including a blood pressure test, BMI and waist measurement, will give you a good idea of your heart health and show you if you need to make any lifestyle changes or need treatment.

    A cholesterol check involves a simple blood test. Your healthcare professional should also check another blood fat called triglycerides, as these also affect your heart health.

    How Is A Total Cholesterol Test Different From An Hdl Test

    HDL is a type of cholesterol that is often referred to as good cholesterol. While HDL is included in total cholesterol, an HDL test measures the amount of this specific kind of cholesterol in the blood.

    Total cholesterol and HDL are minimally affected by recent food consumption, so non-fasting cholesterol tests frequently include these two measurements. In some people, these measurements are sufficient to calculate a persons level of bad cholesterol.

    What Is An At

    Much like a cholesterol test you might take at a healthcare facility, at-home cholesterol test kits usually works by taking a sample of your blood. This blood test is used to measure the following:

    • HDL cholesterol â Also known as âgood cholesterol,â high-density lipoprotein cholesterol consists of the lipids primarily responsible for transporting excess LDL cholesterol to the liver.
    • LDL cholesterol â Low-density lipoprotein cholesterol is sometimes called âbad cholesterol.â Thatâs because too much LDL cholesterol can result in arterial blockage, leading to a high risk of heart attacks, strokes, and heart disease.
    • Total cholesterol â Total cholesterol is the total measure of HDL and LDL cholesterol present in the body.
    • Triglycerides â Triglycerides are excess calories that your body has converted into fats and stored in fat cells. Having high triglyceride levels may lead to health issues, from obesity to diabetes.

    How much information the test kit provides depends on the type of test you choose. Some may only give a reading of your total cholesterol, while others may give a breakdown of HDL, LDL, and triglycerides. Understanding the difference between LDL vs HDL cholesterol as well as comparing the different kinds of tests available, can help you determine which will provide the information you needâand in a way that works for you.
