If you’ve been told you have “plaque” in your arteries—or you’re trying to prevent it—your next question is usually the same: can plaque be reversed?

The honest answer: sometimes you can reduce the softer, cholesterol-rich portion of plaque and (very importantly) stabilize it so it’s less likely to rupture and cause a heart attack or stroke. The calcified portion often doesn’t disappear, but your risk can still improve dramatically when the underlying drivers are corrected.

And that’s where lab testing shines: labs don’t “see” plaque directly, but they measure the forces that build it—and the progress you’re making to stop it.

What Plaque Really Is (and What “Reversal” Usually Means)

Plaque is not just “clogged pipes.” It’s a living process in the artery wall driven by:

• Atherogenic particles (especially LDL particle burden—often best reflected by ApoB)
• Inflammation (your immune system reacting inside the vessel wall)
• Blood sugar and insulin resistance
• Blood pressure injury
• Smoking / nicotine exposure
• Genetics (notably Lp(a))

Most successful prevention plans aim to:

1. Lower the number of artery-damaging particles,
2. Reduce inflammation and metabolic stress, and
3. Track results with objective data.

A Word on Calcium Scores (CAC)

Some protocols claim they can reduce coronary calcium scores by small percentages. Calcium scoring can be a useful marker of risk, but CAC is not a perfect “plaque reversal” scoreboard. Calcium can rise even while plaque becomes more stable. So, if you’re tracking CAC, it’s best used alongside labs that confirm your risk drivers are improving.

The Lab Markers That Matter Most for Plaque Risk

Here are the highest-impact lab categories for detecting and monitoring plaque risk:

1) Lipids and Particle Burden (the “plaque fuel”)

• Lipid Panel (Total-C, LDL-C, HDL-C, Triglycerides)
• Apolipoprotein B (ApoB) (best single lab for “how many atherogenic particles”)
• Lipoprotein(a) [Lp(a)] (genetic risk marker—often overlooked)

2) Inflammation (the “plaque fire”)

• hs-CRP (high-sensitivity C-reactive protein)
• (Optional in deeper workups: Lp-PLA2, fibrinogen

3) Metabolism and Insulin Resistance

• Hemoglobin A1c
• Fasting insulin
• Comprehensive Metabolic Panel (CMP) (includes Glucose, liver and electrolytes—important for medication and overall metabolic status)

4) Kidney and Vascular Risk

• eGFR/creatinine (in CMP)
• Urine albumin/creatinine ratio (microalbumin) (a strong marker of vascular risk)

5) Thyroid (because it can drive lipids)

• TSH
• Free T4 (and sometimes Free T3)

Good / Better / Best Lab Panels for Plaque Detection + Monitoring (Ulta Lab Tests)

Below are ready-to-use bundles you can build using Ulta Lab Tests panels and/or individual tests. (Different brands call panels different names; the key is the test list.)

Frequency tip (general): baseline, then 8–12 weeks after a major change (diet/meds), then every 6–12 months once stable—unless your clinician advises more often.

---

GOOD: Core “Know Your Numbers” Atherosclerosis Screen

Best for: anyone starting prevention, mild risk factors, or annual monitoring.

Include:

• Lipid Panel
• Hemoglobin A1c
• Comprehensive Metabolic Panel (CMP)
• hs-CRP

What it tells you: baseline cholesterol pattern, sugar control, major organ function, and systemic inflammation.

Atherosclerotic Risk Screening Panel (GOOD): This panel includes all core tests listed above—Lipid Panel, Hemoglobin A1c, Comprehensive Metabolic Panel (CMP), and hs-CRP—to establish a baseline view of cardiovascular risk drivers.

---

BETTER: Advanced Cardio-Metabolic Risk Panel

Best for: family history, metabolic syndrome, elevated LDL/TG, or “I want the real story” prevention.

Include everything in GOOD, plus:

• ApoB
• Lp(a)
• Fasting insulin (and fasting glucose if not already included)
• CBC (complete blood count) (helpful for overall health/inflammation context)

What it tells you: how many artery-damaging particles you have (ApoB), whether genetics are amplifying risk (Lp(a)), and how strongly insulin resistance is driving the process.

Atherosclerosis Risk & Advanced Cardiometabolic Panel (BETTER): This panel includes everything in the GOOD panel, plus all additional tests listed above—ApoB, Lp(a), fasting insulin, and a CBC with differential—for a deeper cardiometabolic risk assessment.

---

BEST: Most Comprehensive “Plaque & Prevention” Monitoring Stack

Best for: known coronary disease, high CAC, strong family history, or aggressive prevention goals.

Include everything in BETTER, plus:

Lipids / Particles

• Lipid Panel
• ApoB
• Lp(a)
• ApoA1

Inflammation / Vascular Risk

• hs-CRP
• Lp-PLA2 and/or fibrinogen

Metabolic / Insulin Resistance

• Hemoglobin A1c
• Fasting glucose
• Fasting insulin
• CMP

Kidney / Endothelial Stress

• Urine microalbumin/creatinine ratio

Thyroid (lipid driver)

• TSH
• Free T4 (± Free T3)

Atherosclerosis Risk & Comprehensive Monitoring Panel (BEST): This panel includes every test listed above in the GOOD and BETTER panels, plus the expanded monitoring tests listed above—urine microalbumin/creatinine ratio, TSH, and Free T4—with optional add-ons available for the most comprehensive risk and progression tracking.

Optional “add-ons” depending on your story

• Vitamin D (common deficiency; supportive, not a plaque “cure”)
• Homocysteine (only if clinically relevant; not always actionable)
• Omega-3 index (if you’re actively managing triglycerides via omega-3 strategy)

What it tells you: a full picture of the “inputs” that drive plaque—particles, inflammation, insulin resistance, kidney vascular health, and thyroid contributors—so you can measure improvement objectively.

How to Use These Results (Simple, Practical Targets)

These are common clinician-used directionally helpful goals (not personal medical advice):

• ApoB: lower is generally better for plaque risk; “high-risk” patients often target very low ApoB with clinician guidance
• Lp(a): if elevated, it’s a “once-in-a-lifetime” risk marker—focus becomes aggressive control of everything else
• hs-CRP: aim low; rising trends matter
• A1c / insulin: improving insulin resistance often improves triglycerides, HDL, inflammation, and weight
• Triglycerides: lowering often signals better metabolic health

Your clinician can personalize targets based on whether you have known disease, CAC results, diabetes, or family history.

What Labs Can’t Do (and What to Pair Them With)

Labs can’t directly measure plaque size. To look at plaque more directly, clinicians may use:

• Coronary artery calcium (CAC) scan
• CT coronary angiography (CCTA) (in select situations)
• Stress testing (if symptoms or high risk)

But even when imaging is used, labs are how you monitor whether the plaque-driving biology is improving.

FAQ Section

Q: Can lab tests show plaque in my arteries?
Labs don’t directly measure plaque size. They measure the drivers of plaque—like atherogenic particles (ApoB), inflammation (hs-CRP), blood sugar/insulin resistance, and genetic risk (Lp(a)). These markers help you monitor whether your risk is improving.

Q: What’s the #1 lab marker for plaque risk?
For many people, ApoB is one of the most actionable markers because it reflects the number of artery-damaging particles circulating in the blood.

Q: If my LDL looks normal, do I still need ApoB?
Sometimes, yes. LDL-C can look acceptable while particle burden remains high. ApoB can reveal “hidden” risk.

Q: How often should I re-test?
Many people re-test 8–12 weeks after major changes (diet, weight loss, medications), then every 6–12 months once stable. Your clinician may recommend a different schedule.

Q: Should I get a coronary calcium scan (CAC) too?
CAC can be a helpful risk stratification tool for some people. It’s best used alongside labs because calcification doesn’t always move in the same direction as risk improvement.

Q: Do I need a doctor’s order?
Ulta Lab Tests makes it easy to order testing and receive results. If physician review is required for your state or selected test, options are available during checkout (depending on your program setup).
