What's this test for?

This test is ideal if you're concerned about your heart health, especially if you have a family history of heart disease or have been told your cholesterol numbers look fine but you still worry about your risk. Apolipoprotein B (Apo B) can be elevated even when standard LDL cholesterol looks normal, so this test helps catch hidden risk that a typical cholesterol panel might miss. It's especially useful if you have other risk factors like diabetes, high blood pressure, or a history of heart problems in your family.

What's included in this test?

This test measures a single, focused marker called Apolipoprotein B, which is the main protein found on the particles that carry "bad" cholesterol through your bloodstream. Because every one of these particles carries exactly one Apo B molecule, this number gives a more accurate count of how many potentially artery-clogging particles you actually have, even when your LDL cholesterol number looks normal.

What happens after I get my results?

Your results will show up in your online account with your Apo B value and a clear explanation of what the normal range means. If your level is high, simple next steps like adjusting your diet, increasing physical activity, and rechecking in a few months can help bring it down, while very high results paired with other symptoms may call for prompt medical attention. You can download a standard lab report directly from your account any time you need it. The trends feature also lets you track your Apo B level over time so you can see if your changes are working.

How can I naturally support healthy Apo B levels?
Eating more fiber-rich foods like oats, beans, and vegetables can help lower the number of cholesterol-carrying particles in your blood. Cutting back on saturated fat, added sugar, and processed foods while adding more healthy fats like olive oil, nuts, and fatty fish also makes a real difference. Regular exercise, maintaining a healthy weight, and quitting smoking are additional natural ways to support better numbers over time.
When will I get my results?
Results are typically ready within about 7 days of your blood draw. Once they're finalized, they'll be uploaded straight to your secure online account, and you'll be notified so you can log in and review them at your convenience.
Who should consider this test?
This test is a good option for anyone with a family history of heart disease, diabetes, high blood pressure, or a personal history of high cholesterol. It's also useful if you've had a normal LDL result in the past but still want a clearer picture of your heart disease risk. People who are overweight, sedentary, or smokers may also benefit from checking this marker.
What symptoms indicate I may need this test?
Heart-related risk often has no obvious symptoms, which is exactly why this test can be so valuable. However, warning signs like chest discomfort, shortness of breath during activity, unusual fatigue, or a family history of early heart attacks are all good reasons to check your Apo B level. If you're experiencing chest pain or pressure right now, seek medical care immediately rather than waiting for test results.
What is Apolipoprotein B and why does it matter?
Apolipoprotein B is a protein that sits on the surface of the particles that carry cholesterol through your blood, including LDL, the type often called "bad" cholesterol. Because each particle has exactly one Apo B protein, measuring it tells you the actual number of these particles circulating in your body, not just how much cholesterol they're carrying. A high particle count can mean more risk for artery buildup, even if your standard cholesterol numbers look okay.
What does a high Apo B result mean?
A high Apo B result means you have a larger number of cholesterol-carrying particles in your blood, which can increase your risk of plaque buildup in your arteries over time. This is worth taking seriously even if your regular LDL cholesterol test came back normal. Simple lifestyle changes like improving your diet, increasing exercise, and losing excess weight are good first steps, and retesting in a few months can show if those changes are helping.
How often should I retest?
If your first result is in the healthy range and you don't have other major risk factors, checking again once a year alongside your routine bloodwork is usually enough. If your level is high or borderline, retesting every 3 to 6 months after making lifestyle changes can help you see if those changes are working. Anyone actively working to lower their numbers should retest more frequently to track progress using the trends feature in their account.

Demo results
Apolipoprotein B 105 mg/dL
Demo results
Low (<60 mg/dL) Optimal (60-89 mg/dL) High (>90 mg/dL)
105 mg/dL

What this means

A result of 105 mg/dL falls above the optimal range, meaning you have more cholesterol-carrying particles in your blood than is ideal for heart health. This can raise your risk of artery buildup over time, even if your regular LDL cholesterol number looks normal. It's a good signal to make some lifestyle adjustments and recheck in a few months.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
