Question 1

Do I really need to fast for 12 hours before a lipid panel?

Accepted Answer

Fasting is not necessary for this profile; however, fasting (12 to 14 hours preferred; eight hours acceptable) prior to collection of the specimen is recommended where the triglyceride value provides a prior diagnostic information. While some organizations now allow non-fasting lipid panels for routine screening, fasting provides the most accurate triglyceride measurements and ensures consistency with established reference ranges.

Question 2

Can medications affect my lipid panel results?

Accepted Answer

Yes, several medications can influence cholesterol and triglyceride levels. Statins and other cholesterol-lowering medications will typically reduce LDL cholesterol levels, while some medications like beta-blockers or diuretics may affect triglyceride levels. It's important to continue taking prescribed medications as directed and inform your healthcare provider about all medications and supplements when interpreting results.

Question 3

What's the difference between 'good' and 'bad' cholesterol?

Accepted Answer

HDL cholesterol moves cholesterol out of your arteries. LDL cholesterol moves cholesterol into your arteries. This is sometimes called the "good" cholesterol because higher levels are associated with a lower risk for cardiovascular events. HDL brings excess cholesterol from other areas of the body and returns it to the liver for recycling. LDL cholesterol can build up in artery walls, contributing to plaque formation.

Question 4

How often should I get a lipid panel if my levels are normal?

Accepted Answer

The American Heart Association recommends all adults ages 20 or older have their cholesterol checked every four to six years if their risk remains low. Per CDC recommendations, you should test your cholesterol levels every 4 to 6 years. However, if you have heart disease, diabetes or a family history of high cholesterol, your provider may recommend you check your cholesterol more frequently.

Question 5

What should I do if my triglycerides are elevated but my cholesterol is normal?

Accepted Answer

Some people who are overweight may get heart disease not because their LDL is high but, rather, because their HDL is low and their triglycerides are high. That relationship can cause heart disease as much or even more than just high LDL cholesterol. Elevated triglycerides may indicate metabolic issues and should be addressed through dietary changes, weight management, and potentially medication, even when other cholesterol levels appear normal.

Question 6

Can I eat normally after my blood is drawn for the lipid panel?

Accepted Answer

Yes, you can resume normal eating immediately after your blood draw. Since you've been fasting for 12 hours before the test, it's important to eat something soon after to maintain stable blood sugar levels. There are no dietary restrictions following the test, and you can return to your regular activities right away.
