What Blood Test to Check Cholesterol Levels? A Guide

The primary blood test to check cholesterol is the lipid panel (also called a lipid profile or complete cholesterol test). This panel measures total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), and triglycerides. The lipid panel gives you a comprehensive snapshot of your cardiovascular risk and is the standard recommended by the American Heart Association for adults aged 20 and older. Today, advances in testing have made it easier than ever to order a cholesterol test online from a trusted lab without a doctor visit.

Why a Cholesterol Blood Test Matters

High cholesterol often has no symptoms, but it can lead to plaque buildup in arteries, increasing the risk of heart attack and stroke. Regular testing helps catch problems early. The U.S. Preventive Services Task Force recommends screening every 4–6 years for most adults, and more frequently for those with risk factors like diabetes, family history, or smoking.

What Is Included in a Standard Lipid Panel?

A standard lipid panel includes four key measurements:

• Total Cholesterol – The sum of all cholesterol in your blood.
• LDL Cholesterol – The “bad” cholesterol that can clog arteries.
• HDL Cholesterol – The “good” cholesterol that helps remove LDL.
• Triglycerides – A type of fat in the blood linked to diet and metabolism.

Advanced Cholesterol Tests for More Insight

While the lipid panel is sufficient for most people, advanced tests can provide additional detail, especially for those with intermediate risk or family history of early heart disease.

Apolipoprotein B (ApoB)

ApoB is a protein that carries all atherogenic particles, including LDL. It is considered a more accurate marker of cardiovascular risk than LDL alone. The American College of Cardiology now recommends ApoB testing in certain high-risk patients.

Lipoprotein(a) [Lp(a)]

Lp(a) is a genetic variant of LDL that increases clotting risk. It is not affected by lifestyle changes, but knowing your level helps tailor treatment. The current guidelines suggest testing Lp(a) at least once in every adult.

LDL Particle Number (LDL-P)

LDL-P measures the number of LDL particles, not just the amount of cholesterol they carry. It can identify risk even when LDL cholesterol is normal. This test is especially useful for people with diabetes or metabolic syndrome.

How to Prepare for Your Cholesterol Test

Most lipid panel tests require a 9–12 hour fast (water only) for accurate triglyceride and LDL results. However, some labs now offer non-fasting lipid panels that are acceptable for screening. Always follow the instructions provided with your test kit.

When to Consider a Blood Test for Cholesterol

You should consider a cholesterol blood test if you:

• Are 20 years or older and haven’t been tested in the last 4 years
• Have a family history of high cholesterol or heart disease
• Have high blood pressure, diabetes, or obesity
• Smoke or have a sedentary lifestyle
• Are starting or adjusting cholesterol-lowering medication
