Why the test is performed

Most often, this test is done to help determine the cause or specific type of hyperlipidemia .

Normal Values

The normal range is 50 - 150 mg/dL.

Normal value ranges may vary slightly among different laboratories. Some laboratories use different measurements or may test different specimens. Talk to your doctor about the meaning of your specific test results.

What abnormal results mean

An abnormal result may mean you have high lipid levels (hyperlipidemia).

Other disorders that may be associated with high apoB100 levels include angina pectoris and heart attack .

What the risks are

  • Excessive bleeding
  • Fainting or feeling light-headed
  • Hematoma (blood accumulating under the skin)
  • Infection (a slight risk any time the skin is broken)
  • Multiple punctures to locate veins

Special considerations

Apolipoprotein measurements may provide more detail about your risk for heart disease, but the added value of this test beyond a lipid panel is unknown.
