Apolipoprotein B (Apo B)
Counts the atherogenic particles that drive plaque, catching cardiovascular risk LDL cholesterol alone can miss.
Consider this test if:
- Building a cardiovascular baseline beyond a standard cholesterol panel
- Family history of early heart attack, stroke, or high cholesterol
- High triglycerides, type 2 diabetes, or metabolic syndrome, where LDL cholesterol can understate risk
- Tracking whether a statin, diet change, or other lipid therapy is lowering particle count
- Borderline LDL results and you want a clearer read on actual particle burden
- HSA/FSA eligible
- Typical results in 1-2 days · Reviewed by a real clinician
- Drawn at a CLIA/CAP-accredited lab near you ·
Pre-test considerations
Fasting is not required for ApoB itself. Fast 12 to 14 hours if triglycerides are a specific concern, such as screening for familial hypercholesterolemia, early-onset heart disease, or very high triglycerides. Keep diet and any lipid-lowering medication consistent before retesting so results are comparable.

What this test is for
Apolipoprotein B (ApoB) is the structural protein on every atherogenic lipoprotein, including LDL, VLDL, and Lp(a), so one ApoB molecule sits on each particle that can lodge in an artery wall. Measuring it counts the number of those particles directly, which is what drives atherosclerosis, rather than the amount of cholesterol they carry. This matters because two people with identical LDL cholesterol can have very different particle counts, and the one with higher ApoB carries more risk. It is useful both for setting a cardiovascular baseline and for sharpening risk in people with metabolic syndrome, type 2 diabetes, high triglycerides, or a family history of early heart disease, where standard LDL can read deceptively reassuring.
This is the standalone ApoB measurement. The Apo A1/B panels add apolipoprotein A-1 and the A1/B ratio for a fuller lipoprotein picture, and the extended lipid panel folds ApoB into a full cholesterol workup.

Frequently asked questions
View all FAQsHow does pricing work?
Every test shows the member price next to the standard non-member price, so you can see what membership saves you. The member price is our cost — covering the lab and what it takes to run the service — never a profit on the test itself; Mito makes its money on the $9 membership, not on marking up your tests. Membership is $9/mo, and you still pay the lab’s order fee. Prices are itemized before you pay, with no hidden fees.
Where do I get tested?
Choose a partner lab (Quest, Labcorp, or BioReference) at checkout. If your cart spans multiple tests, we consolidate the whole order onto a single lab so you only make one visit.
Is this eligible for HSA/FSA?
Yes. This test is HSA/FSA eligible, and you can pay with your HSA/FSA card at checkout.
When will I get my results?
Your results post to your dashboard once your lab completes them, then a clinician reviews them and your full analysis and personalized action plan (with clear next steps) follow. Turnaround varies by test: specialty assays and at-home kits take longer, and each test shows its expected turnaround before you buy.
Do I need a doctor’s order?
No. Mito provides the lab order for you, so you can book and get tested without a separate doctor visit.
