What This Test Measures

Your blood sample is analyzed to check levels of several important fats: total cholesterol, high-density lipoprotein (HDL or 'good' cholesterol), low-density lipoprotein (LDL or 'bad' cholesterol), triglycerides, and non-HDL cholesterol. These numbers help doctors evaluate your risk for conditions like heart disease or stroke.

Why It Matters

High levels of certain fats (like LDL cholesterol) can build up in your arteries, narrowing them and increasing the risk of heart problems. This test helps doctors track your progress with treatments or lifestyle changes.

How the Test Works

A small blood sample is drawn from your arm and sent to a lab. The lab uses advanced techniques (like immunoassays or enzymatic methods) to measure each fat component in your blood.

What to Expect Before the Test

No special preparation is needed, but you may be asked to fast for 8–12 hours before testing if triglycerides are included. Wear loose clothing for easy access to your arm.

Reference range

Optimal: <100 mg/dLN/A

Specimen: fluid

Fasting for 12-14 hours preferred. Water is permitted. Avoid alcohol for 24 hours before the test.

Frequently asked questions

Why might my doctor order this test?
Your doctor may recommend this test if you have a family history of high cholesterol, heart disease, or diabetes; if you’re over 20 years old (or younger with risk factors); or if you’re planning to start a medication that could affect your cholesterol levels.
What do my results mean?
Results help identify whether your cholesterol is too high or low. High LDL or triglycerides may require lifestyle changes (like diet or exercise) or medication. Low HDL might need further evaluation with your doctor.
Can I lower my cholesterol naturally?
Yes! Diet (e.g., more fiber, nuts, and fish), exercise, and quitting smoking can help. Ask your doctor about personalized recommendations based on your test results.
