Apolipoprotein B100


Alternative Names:

ApoB100; Apoprotein B100

How the test is performed:

A blood sample is needed.

How to prepare for the test:

Your health care provider may tell you not to eat or drink anything for 4 - 6 hours before the test.

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.
