What's this test for?

This test is ideal if you're experiencing risk factors for heart disease, like high cholesterol, a family history of heart attacks, or unclear results from a standard lipid panel. It looks past the basic cholesterol numbers to measure the actual size and number of the particles that carry cholesterol through your blood. This helps explain why some people with normal cholesterol still face heart risks, and why others may be at higher risk than their standard results suggest.

What happens after I get my results?

Your results show up in your account with each particle measurement explained alongside its normal range, so you can see exactly where you stand. If your small LDL particles or particle count is elevated, simple next steps include cutting back on refined carbs and added sugar, adding more fiber and healthy fats, and staying active, then retesting in a few months to track change. The full lab report is available to download anytime, and you can use the trends feature to watch your particle patterns shift over time as you make changes.

What's included in this test?

This test measures lipoprotein particle size and concentration across the full spectrum: HDL3, HDL2, small LDL, intermediate LDL, large LDL, IDL, and small, medium, and large VLDL, using ion mobility technology. Knowing particle size and count matters because two people with the same total cholesterol can have very different heart disease risk depending on whether their LDL particles are small and dense or large and buoyant, and this direct measurement approach gives a clearer picture than calculated estimates.

How can I naturally support healthy lipoprotein particle size?

Cutting back on refined carbs, white bread, and sugary drinks is one of the most effective ways to shift small dense LDL particles toward the larger, less risky type. Adding more soluble fiber from oats, beans, and vegetables, along with healthy fats like olive oil, nuts, and fatty fish, can also help improve your particle profile. Regular aerobic exercise and losing excess weight around the midsection tend to have a strong positive effect on particle size over a few months.

When will I get my results?

Results are typically ready within about 7 days of your blood draw. Once ready, they're posted directly to your secure online account, where you can view each particle measurement and what it means. You'll get a notification as soon as your report is available.

Who should consider this test?

This test is a good fit for anyone with a family history of early heart disease, existing high cholesterol, diabetes or prediabetes, or a standard lipid panel that doesn't fully explain their risk. It's also useful for people who want a more detailed picture before starting or adjusting a heart-health plan. Athletes and health-conscious individuals who want deeper insight into their cardiovascular risk beyond basic cholesterol also often choose this test.

What symptoms indicate I may need this test?

Heart disease risk often has no symptoms at all, which is exactly why this test can be valuable. That said, things like unexplained fatigue, chest tightness during activity, or a family history of heart attacks at a young age are reasons to look closer. If you've already been told your cholesterol is borderline or high, this test can clarify how concerned you should actually be.

What does a high small LDL particle count mean?

A high number of small, dense LDL particles means more of these particles can squeeze into your artery walls and contribute to plaque buildup, even if your total cholesterol looks normal. This is considered a higher-risk pattern for heart disease than having fewer, larger LDL particles. The good news is this pattern often responds well to diet changes, increased activity, and weight loss.

What causes an unhealthy lipoprotein particle pattern?

Diets high in refined carbohydrates and sugar are one of the biggest drivers of small, dense LDL particles. Excess weight, especially around the abdomen, insulin resistance, lack of exercise, and genetics also play a strong role. Smoking and chronic stress can make the pattern worse over time as well.

How often should I retest?

If your results show an elevated risk pattern and you're making lifestyle changes, retesting every 3 to 6 months is a reasonable way to track progress. If your particle profile looks healthy, checking again once a year is generally enough. Use the trends feature in your account to see how your numbers move over time.
