Lipid Panel with Non-HDL Cholesterol
Does this test have other names?
What is this test?
This blood test checks the levels of cholesterol in your body. A lipid panel will
show the levels of your total cholesterol, your LDL ("bad") cholesterol, and your
HDL ("good") cholesterol. In general, the higher your total and LDL cholesterol levels,
the higher your risk for coronary heart disease. But some heart attacks happen in
people who don't have a high LDL level.
Some researchers believe that measuring your non-HDL cholesterol levels gives a better
assessment of the risk for heart disease than measuring only LDL. This is especially
true if you have high triglycerides. Your non-HDL cholesterol level is found by subtracting
your HDL cholesterol from your total cholesterol.
Why do I need this test?
You may need this test to see if you have high cholesterol. High cholesterol is one
of the things that can tell you how likely you are to get heart disease, so it's important
to know your cholesterol numbers. When your LDL cholesterol level is high and HDL
cholesterol is low, you may be at risk for a heart attack or stroke.
Here's a breakdown of LDL cholesterol levels and health:
Less than 70 milligrams per deciliter (mg/dL) – if you're at very high risk for a
heart attack or had a heart attack
Less than 100 mg/dL – normal/optimal
100 to 129 mg/dL – near or above the optimal
130 to 159 mg/dL – borderline high
160 to 189 mg/dL – high
190 mg/dL and above – very high
Here's a breakdown of total cholesterol levels and health:
Less than 200 mg/dL – desirable
200 to 240 mg/dL – borderline high
240 mg/dL and above – high
Ideally, HDL cholesterol should be above 40 mg/dL for men and above 50 mg/dL for women.
The higher your HDL level, the better.
The test for non-HDL cholesterol isn't usually part of screening for your total cholesterol.
But if you have high blood pressure, diabetes, or other risk factors for heart disease,
your chances of having a heart attack are higher than normal. In these cases, your
provider may calculate your non-HDL cholesterol, too.
Your provider may also order this test if a blood test shows you have high levels
of triglycerides, another type of fat in the blood. A high non-HDL cholesterol level
alone isn't a warning sign that something is wrong with your arteries or heart, but
if your triglycerides measure more than 200 mg/dL, your provider may prescribe medicine
to help lower both your LDL and your non-HDL cholesterol.
What other tests might I have along with this test?
If your provider suspects you have heart disease, you may also get these tests:
Electrocardiogram (ECG). This tests your heart's electrical impulses to see if your heart is beating normally.
Stress test. This test is done while you have an ECG. You may have to walk or run on a treadmill.
Echocardiogram. This is a picture of your heart made from sound waves.
Cardiac catheterization. A tube is put into your blood vessel and dye is injected. Clogs in the arteries of
your heart will then show up on an X-ray.
People with a history of artery disease, stroke, kidney disease, or diabetes are also
at higher risk for heart disease, so tests may be done to look for these problems,
What do my test results mean?
Test results may vary depending on your age, gender, health history, the method used
for the test, and other things. Your test results may not mean you have a problem.
Ask your healthcare provider what your test results mean for you.
Although no clear standards exist for non-HDL levels, most medical experts believe
that lowering LDL and non-HDL cholesterol at the same time will cut your heart disease
According to cholesterol guidelines, your non-HDL cholesterol level goal should be
30 mg/dL higher than your LDL cholesterol level goal. For example, if you are aiming
for an LDL cholesterol of 100 mg/dL, then your goal for non-HDL should be 130 mg/dL.
If you have diabetes, smoke, have a family history of heart disease, or have other
risk factors, your cholesterol levels may need to be much lower. Talk with your healthcare
provider about where your cholesterol levels should be.
How is this test done?
The test is done with a blood sample. A needle is used to draw blood from a vein in
your arm or hand.
Does this test pose any risks?
Having a blood test with a needle carries some risks. These include bleeding, infection,
bruising, and feeling lightheaded. When the needle pricks your arm or hand, you may
feel a slight sting or pain. Afterward, the site may be sore.
What might affect my test results?
What you eat, how often you exercise, and whether you smoke can affect your cholesterol
levels. So can certain medicines.
How do I get ready for this test?
A lipid test can be done with or without fasting. But if your triglycerides are going
to be measured, you may need to fast. This means you can have nothing but water for
9 to 12 hours before the test. Tell your healthcare provider about all medicines,
herbs, vitamins, and supplements you are taking. This includes medicines that don't
need a prescription and any illicit drugs you may use.
