A
How to Prepare for the Test
You will be asked not to eat anything for 12 hours before the test.
Do not smoke before the test.
How the Test will Feel
A needle is inserted to draw blood. You may feel slight pain, or only a prick or stinging sensation. Afterward, there may be some throbbing.
Why the Test is Performed
High levels of lipo蛋白质 can increase the risk for heart disease. The test is done to check your risk for
It is not yet clear if this measurement leads to improved benefits for patients. Therefore, many insurance companies do not pay for it.
The American Heart Association and American College of Cardiology do not recommend the test for most adults who do not have symptoms. It may be useful for people at higher risk because of a strong family history of cardiovascular disease.
正常的结果
Normal values are below 30 mg/dL (milligrams per deciliter), or 1.7更易与L.
Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
The example above shows the common measurements for results of these tests. Some laboratories use different measurements or may test different specimens.
What Abnormal Results Mean
Higher than normal values of Lp (a) are associated with a high risk for 动脉粥样硬化, 中风, 心脏病发作.
注意事项
Lp (a) measurements may provide more detail about your risk for heart disease, but the added value of this test beyond a standard lipid panel is unknown.
