Definition Return to top
A coronary risk profile is a battery of blood tests to measure your cholesterol and triglyceride levels. The profile can help determine your risk for heart disease.
How the Test is Performed Return to top
Blood is typically drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.
Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm.
Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.
In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.
The blood is sent to a laboratory, where the following are measured:
Additional blood tests, such as C-reactive protein (CRP), may be added to the profile in some laboratories.
How to Prepare for the Test Return to top
You should not eat or drink anything except water for 9-12 hours before having your blood drawn.
How the Test Will Feel Return to top
When the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.

Normal Results Return to top
The ideal values are different for people without coronary artery disease or other risk factors than for those with known coronary artery disease, diabetes, or high blood pressure.
Note: mg/dL = milligrams per deciliter
Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
What Abnormal Results Mean Return to top
Abnormal values may be a sign that you are at increased risk for atherosclerosis and related disorders, including:
Risks Return to top
Veins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.
Other risks associated with having blood drawn are slight but may include:
