The 2026 ACC/AHA guideline supports measuring Lp(a) at least once in adulthood. ApoB is more selective: it can help when triglycerides are high, when you have diabetes or metabolic risk, or when LDL looks fine but risk seems higher. Neither replaces a full risk estimate with your clinician.
What actually changed in the 2026 guideline
In 2026, a multisociety group led by the American College of Cardiology and American Heart Association published an updated dyslipidemia guideline in Circulation. The changes that matter most to a person holding a lab report include the following:
- PREVENT is the recommended risk calculator for adults ages 30 to 79.
- Lp(a) should be measured at least once.
- ApoB and coronary artery calcium (CAC) scoring have defined roles in selected people.
- LDL goals are tied to risk tier, so lower-risk and higher-risk people may be treated toward different numbers.
This article does not quote specific LDL numbers for each tier. Those belong with the guideline itself and your own clinician. That is also the practical answer to “what is a good LDL?” in 2026: it depends on your risk tier, not on a single cutoff that applies to everyone.
Lp(a): the test most people have never had
What it is
Lipoprotein(a), or Lp(a), is an LDL-like particle with an extra protein attached. Your level is set mostly by genetics. It tends to stay fairly stable across adulthood and changes little with diet, exercise or weight loss. That is why one measurement is usually enough to learn where you stand.
Why a normal LDL does not rule it out
A standard lipid panel does not report Lp(a). The LDL cholesterol number can include some of the cholesterol carried by Lp(a), but it does not tell you how much Lp(a) you have. Someone can have an unremarkable LDL and still carry a high Lp(a), which is associated with a higher lifetime risk of heart attack, stroke and aortic valve disease. If you have been wondering whether you need a cholesterol test when your LDL is normal, this is one of the reasons to ask your clinician.
Who should get one
Because the guideline supports at least one lifetime measurement, a reasonable answer to “should every adult get an Lp(a) test?” is: many adults can reasonably have it done once, and it may be especially relevant if you:
- have a family history of early heart disease or stroke
- have had a heart attack, stroke or stent without a clear explanation
- have a very high LDL, or a family history of familial hypercholesterolemia
- have a borderline risk estimate and are deciding whether to start a statin
Results come in either mg/dL or nmol/L, and the two do not convert cleanly. The 2018 AHA/ACC cholesterol guideline used roughly 50 mg/dL (125 nmol/L) or higher as a risk-enhancing level. Make sure you know which unit your lab used before comparing results.
What an elevated result does and does not mean
A high Lp(a) is a risk marker, not a diagnosis. Statins do not reliably lower it. In practice, the clinical response is usually to be more thorough with the risk factors that can be changed: LDL, blood pressure, blood sugar, smoking, and sometimes a CAC scan. Therapies aimed specifically at Lp(a) have been studied in clinical trials, but as of this writing none is established for routine use, so check current status with your clinician. First-degree relatives may want to ask their own clinicians about testing, since the trait runs in families.
ApoB: counting particles instead of cholesterol
LDL cholesterol measures the cholesterol inside particles. ApoB counts the particles themselves, because each atherogenic particle (LDL, remnant particles and Lp(a)) carries one ApoB molecule. Think of it as counting delivery trucks instead of weighing the cargo.
Usually the two measures agree. They can diverge, and ApoB may add the most when:
- triglycerides are elevated
- you have type 2 diabetes, prediabetes, obesity or metabolic syndrome
- your LDL is at or near goal but your overall risk or family history suggests otherwise
- you are already on treatment and your clinician wants to look at residual risk
If your lipids are straightforward and your risk is low, you may not need it. ApoB is a refinement, not a mandatory add-on, and a lab can usually run it on the same blood draw.
PREVENT: the risk estimate behind the decisions
The PREVENT equations estimate your 10-year risk of cardiovascular disease, including heart failure, and a 30-year risk for younger adults. They use factors such as age, sex, cholesterol, blood pressure, diabetes, smoking and kidney function, and they are intended to replace the older Pooled Cohort Equations. They do not use race, and they include kidney function, which older tools left out.
Limits worth knowing: PREVENT is built for ages 30 to 79, and it is not intended for people with familial hypercholesterolemia, such as a very high LDL (190 mg/dL or higher) or a strong family pattern. In those cases, risk is driven by genetics and the calculator may underestimate it. A risk estimate is also only as good as the numbers entered, so recent, accurate blood pressure and lab values matter.
Coronary calcium score: when a picture helps
A CAC score comes from a quick, non-contrast CT scan of the heart that measures calcified plaque in the coronary arteries. It is most useful when the decision is genuinely uncertain, for example a borderline risk estimate and a person unsure about starting a statin.
- A score of zero generally points to lower short-term risk, which can support delaying or avoiding medication in some people.
- A higher score shows plaque is already present and often pushes toward treatment.
- Limits: a zero does not exclude soft, non-calcified plaque, particularly in younger people, and it does not rule out the added risk from a very high Lp(a) or a strong family history. It involves a small amount of radiation, and insurance coverage varies.
CAC is a tool for selected people, not a routine screen for everyone.
What to ask for, and what it may cost
A practical request list at your next visit:
- “Can we calculate my PREVENT risk with current numbers?”
- “Should I have an Lp(a) measured once?”
- “Would ApoB add anything given my triglycerides or blood sugar?”
- “Is a calcium score reasonable for my situation?”
- “What is my LDL goal under the 2026 guideline, and when do we recheck?”
As for “how much does an Lp(a) test cost?”, there is no single answer. The price depends on the lab, whether it is ordered by a clinician, and how your insurance treats it. Ask for the cash price before the draw, and ask whether the test is covered under your plan. Since Lp(a) is often a one-time test, the sticker price matters less than whether anyone reviews the result with you.
Getting this done around Midlothian
In the Midlothian and greater Richmond area, these tests are often drawn at a commercial or hospital-affiliated outpatient lab on a clinician’s order, though some are sold direct to consumers. The harder part is usually the follow-up: who reads the result, puts it next to your blood pressure, family history and glucose, and decides what changes. A result with no plan attached can easily get lost in a patient portal. If you also want a broader look at inflammation-related markers, our CRP blood test explainer covers what that marker can and cannot tell you. If you are on testosterone therapy, our overview of testosterone and cholesterol is a useful companion read.
Where a direct primary care membership fits
These tests share a pattern: they are ordered once or occasionally, the results need context, and the cost and the wait for review are what frustrate people. Direct primary care models generally aim to offer easier access to a clinician, such as direct messaging, continuity with one clinician over time, and sometimes lower lab pricing. You can read about how a direct primary care membership at Venture Wellness works. Whether that kind of arrangement suits you depends on your health, your insurance and your budget, and it is not necessary for getting these tests done elsewhere.
Practical takeaways
- Ask whether a one-time Lp(a) makes sense for you, especially with early heart disease in the family.
- Do not read a normal LDL as a full all-clear.
- ApoB and CAC are selective tools. They are most useful when your picture is mixed or the decision is close.
- Do not chase a single LDL number from a headline. Your goal depends on your risk tier.
- Call your clinician promptly for chest pain, shortness of breath, or stroke symptoms. Do not wait for a lab review.

Frequently asked questions
Should every adult get an Lp(a) test?
The 2026 ACC/AHA guideline supports measuring Lp(a) at least once, and many adults can reasonably do so. It may matter most if you have early heart disease in your family, a very high LDL, or an unexplained heart event. Talk with your clinician about timing and what you will do with the result.
Do I need a cholesterol test if my LDL is normal?
A normal LDL does not capture Lp(a), particle number, or your overall risk from blood pressure, blood sugar, smoking and family history. Periodic lipid testing is still reasonable, and your clinician can tell you whether Lp(a), ApoB or a risk calculation would add useful information.
Can I lower my Lp(a) with diet or exercise?
Generally, not much. Lp(a) is mostly genetic and changes little with lifestyle. Statins do not reliably lower it. A high level is usually handled by treating the other risk factors more carefully. Therapies targeting Lp(a) are still being studied, so ask your clinician about the current status.
Is a coronary calcium score better than ApoB or Lp(a)?
They answer different questions. Lp(a) reflects an inherited risk factor, ApoB counts atherogenic particles, and a calcium score shows calcified plaque that is already present. A clinician may use one, two or all three depending on your situation. A zero calcium score does not rule out the added risk from a high Lp(a) or a strong family history.
Does the PREVENT calculator work for everyone?
No. PREVENT is designed for adults 30 to 79 and is not intended for people with familial hypercholesterolemia, whose risk is driven by genetics. It is only as accurate as the numbers entered, so recent blood pressure and lab results matter.
