Lipoproteins, HDL, LDL

This is a blood test that measures Lipoproteins in the blood. Lipoproteins are predictors of coronary artery disease. The test on this often is called the Lipid profile. It allows your caregiver to determine if you are at risk for heart disease or other blood vessel problems. Lipoproteins are proteins in the blood that transport cholesterol, triglycerides, and other fats in the blood.

PREPARATION FOR TEST

No food for 12-14 hours prior to testing with only water permitted. Dietary carelessness within a few weeks of the testing will influence the results.

NORMAL FINDINGS

  • HDL

  • Male: greater than 45 mg/dl or greater than 0.75 mmol/L (SI units)

  • Female: greater than 55 mg/dl or greater than 0.91 mmol/L (SI units)

  • LDL: 60-180 mg/dl or less than 3.37 mmol/L (SI units)

  • VLDL: 25% to 50%

Ranges for normal findings may vary among different laboratories and hospitals. You should always check with your doctor after having lab work or other tests done to discuss the meaning of your test results and whether your values are considered within normal limits.

MEANING OF TEST

Your caregiver will go over the test results with you and discuss the importance and meaning of your results, as well as treatment options and the need for additional tests if necessary.

OBTAINING THE TEST RESULTS

It is your responsibility to obtain your test results. Ask the lab or department performing the test when and how you will get your results.
