A standalone apolipoprotein B (ApoB) test costs $59–$69 cash at online lab services, plus a $0–$6 checkout fee — all prices verified September 4, 2026. The same marker bundled into an advanced heart-health panel runs $215. Here's the full price table, why two providers make you fast and two don't, and what the number actually tells you that a regular cholesterol test doesn't.

Prices below are the advertised direct-pay cash prices recorded from each provider's public product page on September 4, 2026, using the same method as our quarterly Lab Test Price Index. "All-in" adds the per-order fee each provider discloses at checkout. All four standalone options are drawn at Quest or Labcorp patient service centers.
| Provider | Test as listed | Cash price | Checkout fee | All-in | Fasting? | |
|---|---|---|---|---|---|---|
| HealthLabs | Apolipoprotein B Test (Apo-B) | $59 Lowest | None listed | $59 | No | Check Price → |
| Walk-In Lab | Apolipoprotein B Blood Test | $59 | $6 physician fee | $65 | No | |
| RequestATest | Apolipoprotein B (Apo B) Blood Test | $65 (Lab 2) / $69 (Lab 1) | $4 service fee | $69–$73 | Yes, 12–14 hrs | Check Price → |
| Labcorp OnDemand | Apolipoprotein B (ApoB) Test | $69 | None listed | $69 | Yes, 12–14 hrs |
Promotions seen on the verification date: Walk-In Lab showed $50.15 with a Labor Day code (through Sept 8, 2026) and Labcorp OnDemand showed $51.75 under a September 25%-off sale. We list sticker prices because promotions expire; if one is running when you order, take it. Quest Health does not sell a standalone ApoB test — see the bundle table below.
| Option | What you get | Cash price |
|---|---|---|
| Quest Health — Advanced Heart Health Test Panel (with ApoB) | Lipid panel, lipoprotein fractionation (ion mobility), ApoB, hs-CRP, Lp-PLA2 activity | $215 + $6 physician fee |
| Build it yourself: ApoB + Lp(a) | The two particle-level markers most routine panels skip. Lp(a) was $49 at HealthLabs, Walk-In Lab, and Labcorp OnDemand on the same date. | $108 at HealthLabs (both tests, no fee) |
| Build it yourself: Lipid panel + ApoB | Standard cholesterol numbers plus particle count. Lipid panels run $23–$51 in our price index. | $82–$120 depending on provider |
The bundled panel is not a bad product — it is a lot of product. If you only want the particle count your last lipid panel didn't include, the standalone test costs about a quarter as much.
Already have a recent lipid panel? Then ApoB is the one add-on worth ordering next; if you have never had cholesterol checked, start with the $23–$51 lipid panel and add ApoB in the same order.
Order at HealthLabs — $59 →What You're Paying For
A standard lipid panel reports how much cholesterol is being carried in your blood (LDL-C, HDL-C, triglycerides). ApoB reports how many particles are carrying it. Every atherogenic particle — LDL, VLDL, IDL, and Lp(a) — carries exactly one ApoB molecule, so the ApoB concentration is effectively a particle count.
That distinction matters because two people can share the same LDL-C number while one has many small, cholesterol-poor particles and the other has fewer, larger ones. The particle count tracks risk more closely. The European Society of Cardiology / European Atherosclerosis Society guidelines recommend ApoB as a risk marker on par with or preferable to LDL-C, and the 2018 AHA/ACC cholesterol guideline lists a persistently elevated ApoB (130 mg/dL or higher) as a “risk-enhancing factor” that can tip a treatment decision. It is most informative when LDL-C is likely to understate risk: high triglycerides, diabetes, obesity, or metabolic syndrome.

Common Questions
Direct-pay: $59–$69 for the standalone test plus a $0–$6 checkout fee, verified September 2026. Bundled into an advanced heart-health panel: $215 plus fee. Through a doctor, the cost depends on whether the test is ordered with a qualifying diagnosis code and how much of your deductible remains.
Depends on where you order. HealthLabs and Walk-In Lab say no; RequestATest and Labcorp OnDemand ask for 12–14 hours. The marker itself is relatively stable non-fasting — the rule is mostly inherited from lipid-panel protocol — but the lab follows the ordering service's instructions, so follow them too.
It measures something different: the number of atherogenic particles rather than the cholesterol mass they carry. Major cardiology guidelines treat it as an equal or better risk marker than LDL-C, especially when triglycerides are high or metabolic syndrome is present. It complements a lipid panel rather than replacing it.
At list price, HealthLabs at $59 with no separate fee and no fasting was the lowest all-in option we verified. Walk-In Lab matches the $59 sticker but adds a $6 physician fee. Short promotions at Walk-In Lab and Labcorp OnDemand can undercut that temporarily; they were running on our verification date and are noted above.
Lab tests for medical care are generally HSA/FSA-eligible (IRS Publication 502) — check with your plan administrator. HealthLabs accepts HSA/FSA cards at checkout; for other services, pay normally and submit the itemized receipt. Our HSA/FSA lab testing guide covers the mechanics.
