An ApoB (apolipoprotein B) test counts the particles that carry cholesterol into your artery walls. Every LDL, VLDL and IDL particle carries exactly one ApoB, so the result shows how many potentially harmful particles you have, which a standard cholesterol test can miss. At Passion Health, ApoB is $60 on its own or included in the $149 Full Blood Work.
What does an ApoB test measure?
Cholesterol travels through the blood inside particles called lipoproteins. LDL, VLDL, IDL and Lp(a) particles each carry one molecule of apolipoprotein B, so an ApoB result works as a particle count. It's the particles, not just the cholesterol inside them, that enter the artery wall and build plaque.
A routine lipid panel measures how much cholesterol those particles hold (LDL-C). Two people with the same LDL-C can have very different particle counts. People with high triglycerides, type 2 diabetes, insulin resistance or extra weight around the middle often carry many small particles, so their ApoB runs higher than their LDL-C suggests.
Who should get an ApoB test?
The 2026 ACC/AHA dyslipidemia guideline says ApoB can improve heart-risk assessment, help decide whether to start cholesterol-lowering treatment, and help identify inherited lipid disorders. It adds the most when you:
- Have type 2 diabetes, prediabetes or insulin resistance.
- Have triglycerides above 200 mg/dL, or an LDL-C that's already below 70 mg/dL on treatment.
- Are already treated and have reached your LDL-C and non-HDL-C goals; ApoB shows whether risk remains.
- Have heart disease, or a mix of heart, kidney and metabolic conditions (cardiovascular-kidney-metabolic syndrome).
The guideline also names a family history of early heart disease and South Asian ancestry as risk-enhancing factors, which your clinician weighs alongside your ApoB.
What is a good ApoB level?
There isn't one normal value for everyone. The 2026 ACC/AHA guideline sets ApoB goals by overall risk, alongside matching LDL-C goals:
| Your situation | ApoB goal | LDL-C goal |
|---|---|---|
| No heart disease, 10-year risk 3% to under 10% (borderline or intermediate) | Under 90 mg/dL | Under 100 mg/dL |
| No heart disease, 10-year risk 10% or higher, or heart disease that isn't very high risk | Under 70 mg/dL | Under 70 mg/dL |
| Heart disease at very high risk | Under 55 mg/dL | Under 55 mg/dL |
At low risk (under 3%), the guideline doesn't set a treatment goal; healthy habits are the focus. Your 10-year risk comes from the American Heart Association's PREVENT equations, which the 2026 guideline uses in place of the older pooled cohort equations. Your clinician then adjusts for things the calculator misses, such as family history, early menopause or South Asian ancestry. The reference range printed on a lab report describes the general population; it isn't your personal goal.
How to prepare for an ApoB test
You don't need to fast for ApoB; the result is reliable after a meal. If it's drawn with a full lipid panel and your triglycerides have run high before, your clinician may ask you to fast so the panel is easier to read. Keep taking your usual medicines unless you're told otherwise.
How to lower ApoB
ApoB comes down with the same steps that lower LDL cholesterol:
- Food. Less saturated fat from fatty meat, butter, ghee and coconut oil; more fiber from oats, beans and lentils.
- Weight and activity. Losing extra weight and exercising regularly lower triglyceride-rich particles, which carry ApoB.
- Alcohol and added sugar. Both raise triglycerides and the particles that carry them.
- Medicines. Statins are the first-choice medicine for lowering ApoB. Ezetimibe, PCSK9 inhibitors and bempedoic acid can be added when needed. The 2026 guideline allows treatment to be intensified when ApoB stays high even though LDL-C and non-HDL-C are at goal.
We usually recheck 8 to 12 weeks after a change in diet or medicine.
If your ApoB is high at Passion Health
A Texas-licensed clinician reviews every result. If your ApoB is above your goal, we look at it together with your PREVENT risk, Lp(a), blood pressure, A1c and family history, then agree on a plan: food and activity changes, medicine when it's warranted, and a recheck date. If your risk is borderline or intermediate and a statin decision is unclear, a coronary calcium score can help decide.
ApoB test cost in Texas
Self-pay. $60, plus one $29 draw and clinician review fee per order. Or get it in the $149 Full Blood Work, which includes 36 results (ApoB, Lp(a), hs-CRP, cholesterol, A1c, kidney, liver and blood count) and waives the fee.
With insurance. If we're in network with your plan, we bill it when the test is covered. You pay cash for a test only after we tell you the price in writing, and Medicare patients sign an Advance Beneficiary Notice first.
ApoB questions
Is ApoB better than LDL cholesterol?
ApoB counts the particles, while LDL-C measures the cholesterol inside them. They usually agree. When they don't, as often happens with diabetes or high triglycerides, ApoB is the better guide to risk. The 2026 guideline keeps LDL-C as the main treatment target and uses ApoB to fine-tune.
What is a good ApoB level?
Under the 2026 ACC/AHA guideline, the goal is under 90 mg/dL for people without heart disease at borderline or intermediate risk, under 70 mg/dL at higher risk, and under 55 mg/dL at very high risk.
Does insurance cover an ApoB test?
Many plans cover ApoB when a clinician orders it for a medical reason, but coverage varies. We check your plan first. Without insurance, it's $60 at Passion Health, or included in the $149 Full Blood Work.
Do I need to fast for an ApoB test?
No. ApoB is accurate without fasting. Your clinician may ask you to fast only if a full lipid panel is drawn at the same time and your triglycerides have been high.
How often should ApoB be checked?
Once as part of a heart-risk check, again 8 to 12 weeks after starting or changing treatment, then usually with your yearly labs.
