What It Is
By ordering a test called a lipid panel for your child, the doctor is taking a look at the different kinds of fats in the blood. While many parents don't think about the level of their child's cholesterol, high levels are known to be contributors to heart disease and strokes. Doctors take a close look at lipid panels in kids because heart disease has been shown to develop in childhood.
A lipid panel measures:
- Total cholesterol, which is the sum of the different types of cholesterol.
- High-density lipoproteins (HDL) cholesterol, commonly called "good" cholesterol. Lipoproteins can be thought of as your child's blood transportation system. High-density lipoproteins carry cholesterol to the liver to be eliminated.
- Low-density lipoproteins (LDL) cholesterol, commonly known as "bad" cholesterol. LDLs that build up in the bloodstream can clog blood vessels and increase the risk of heart disease.
- Triglycerides, which store energy until the body needs it. If the body holds on to too many triglycerides, blood vessels can get clogged and cause health problems.
Why It's Done
The lipid panel checks the lipid levels in blood, which can indicate a person's risk for heart disease or atherosclerosis (a hardening, narrowing, or blockage of the arteries).
Some experts think that high cholesterol in kids is a major under-reported public health problem. So it's important to be aware of your child's cholesterol levels, especially if either parent has high cholesterol.
Lipid levels can be affected by fat in the diet. Your child should avoid eating fatty foods the evening before the test. Unless otherwise instructed by your doctor, your child shouldn't eat or drink anything other than water after midnight the night before the test. Failing to do so could affect the test results.
Your child should also avoid any exercise 12 to 14 hours before the test. Check with your doctor to see if you should discontinue any medications your child is taking until after the test is done.
On the day of the test, it may help to have your child wear a T-shirt or short-sleeved shirt to allow easier access for the technician who will be drawing the blood.
Blood will be taken from a vein. After the skin surface is cleaned with antiseptic, an elastic band (tourniquet) is placed around the upper arm to apply pressure and cause the veins to swell with blood. A needle is inserted into a vein (usually in the arm inside of the elbow or the back of the hand) and blood is withdrawn and collected in an airtight vial or syringe. During the procedure, the elastic band is removed.
Once the blood has been collected, the needle is gently removed and the puncture site covered with cotton or a bandage to stop the bleeding. Collecting blood for this test will only take a few minutes.
What to Expect
Collecting a sample of blood is only temporarily uncomfortable and feels like a slight pinprick. Afterward, there may be some minor bruising, which should go away in a few days.
Getting the Results
Test results should be available within a few days to a week. Your doctor will want to discuss the results and any concerns with you.
Obtaining a blood test such as a lipid panel test is considered safe. However, as with many medical tests, some problems can occur with having blood drawn, like:
- fainting or feeling lightheaded
- hematoma (blood accumulating under the skin causing a lump or bruise)
- pain associated with multiple punctures to locate a vein
Helping Your Child
Having a blood test is relatively painless. Still, many children are afraid of needles. Explaining the test in terms your child can understand might help ease some of the fear.
Allow your child to ask the technician any questions he or she might have. Tell your child to try to relax and stay still during the procedure, as tensing muscles and moving can make it harder and more painful to draw blood. It also may help for your child to look away when the needle is being inserted into the skin.
If You Have Questions
If you have questions about the lipid panel test, speak with your doctor. You also can talk to the technician before the procedure.
