Cardio Lipoprotein Fractionation 1 Baseline Blood Test Panel
This blood test panel breaks down cholesterol into particles, ApoB and key ratios to clarify cardiovascular risk and guide diet or treatment decisions.
This panel bundles multiple biomarker tests in one order—your report explains how results fit together.
This is a lab panel, meaning you get multiple lipid and lipoprotein measurements from one blood draw. It is designed for the common situation where a standard cholesterol test (total cholesterol, LDL-C, HDL-C, triglycerides) does not fully explain your risk—or does not match what you are seeing with diet changes, weight loss, medications, or family history.
Instead of focusing on one number, this panel helps you look at the “cargo count” (how many atherogenic particles you have), the “cargo type” (particle size and distribution), and the context (ratios and related markers) so you can make decisions with less guesswork.
Do I need this panel?
You may consider this panel if your LDL cholesterol (LDL-C) looks “fine” but you have a strong family history of early heart disease, insulin resistance, metabolic syndrome, fatty liver, or persistently high triglycerides. In these situations, LDL-C can underestimate risk because it measures cholesterol content, not how many LDL-like particles are circulating.
This panel is also useful if you are trying to make sense of diet debates (for example, saturated fat changes, low-carb vs. low-fat, or higher-protein plans) and you want to see whether your particle-related markers (like ApoB or LDL particle number) are moving in the same direction as LDL-C.
You might also want this panel if you are already on lipid-lowering therapy (statins, ezetimibe, bempedoic acid, PCSK9 inhibitors, or certain supplements) and you want to confirm that the treatment is lowering the atherogenic particle burden—not just shifting cholesterol between compartments.
Your results can support clinician-directed care, but they are not a diagnosis on their own. The most helpful interpretation comes from combining your panel pattern with your blood pressure, glucose/insulin markers, inflammation markers, family history, and imaging when appropriate.
Lipoprotein fractionation and particle metrics can be measured by different lab methods (for example, NMR, ion mobility, or electrophoresis), so reference ranges and naming may vary by laboratory.

Get this panel with Vitals Vault
Vitals Vault lets you order this advanced lipid lab panel directly and complete testing through a national lab network. You get a single set of results that includes multiple complementary markers, which is often more useful than ordering one test at a time.
After your results post, you can use PocketMD to translate the full pattern into plain language: what looks most important, what may be a temporary fluctuation, and what follow-up questions to bring to your clinician. This is especially helpful when LDL-C and ApoB (or LDL particle number) do not agree, or when triglycerides and HDL patterns suggest insulin resistance.
If you are tracking changes, repeating the same panel over time can help you see whether a diet change, weight loss phase, medication, or training block is improving your atherogenic particle burden and triglyceride-rich lipoproteins—not just the headline cholesterol number.
- Direct-to-consumer ordering with convenient lab access
- One draw, multiple advanced lipid and particle markers
- PocketMD support to interpret results as a pattern
- Designed for trending over time when you repeat the same panel
Key benefits of the Cardio Lipoprotein Fractionation 1 Baseline panel
- Clarifies risk when LDL-C and overall cholesterol do not match your family history or metabolic health.
- Estimates atherogenic particle burden using ApoB and/or particle counts, which can be more predictive than LDL-C alone.
- Breaks LDL into size/distribution patterns so you can spot small, dense LDL–dominant profiles often linked to insulin resistance.
- Adds context with triglyceride-rich lipoproteins and ratios that reflect how you are handling dietary fat and carbohydrates.
- Helps you compare diet changes to bloodwork without relying on a single marker or internet one-liners.
- Supports medication or supplement monitoring by showing whether particle-related targets are improving, not just LDL-C.
- Creates a baseline you can repeat to track trends and reduce noise from one-off results.
What is the Cardio Lipoprotein Fractionation 1 Baseline Blood Test Panel?
This panel is a bundled set of blood tests that evaluates cholesterol and triglyceride transport in your body by measuring both traditional lipids and more detailed lipoprotein particle information.
Cholesterol and triglycerides do not float freely in blood. They travel inside particles called lipoproteins. The main groups include LDL (low-density lipoprotein), HDL (high-density lipoprotein), and VLDL (very-low-density lipoprotein), along with intermediate forms. These particles differ in size, number, and composition.
A key idea is that artery plaque risk is driven more by the number of atherogenic particles that can enter the artery wall than by the amount of cholesterol carried inside each particle. LDL-C tells you the cholesterol content within LDL, while ApoB (apolipoprotein B) and LDL particle number (LDL-P) better reflect how many atherogenic particles are circulating (because each atherogenic particle typically carries one ApoB molecule).
“Fractionation” refers to separating lipoproteins into subfractions (for example, small vs. large LDL) or reporting particle size and counts. This can help explain why two people with the same LDL-C can have different risk profiles—one may have fewer, larger particles, while another may have many smaller particles.
This panel is often used as a baseline because it gives you a starting pattern before you make changes (diet, weight loss, medications) or before you decide whether you need a broader cardiovascular risk workup (such as adding lipoprotein(a), inflammatory markers, or imaging).
LDL-C vs ApoB vs LDL particle number (LDL-P)
LDL-C measures how much cholesterol is inside LDL particles. ApoB and LDL-P are closer to a particle count. If LDL-C is “normal” but ApoB or LDL-P is high, it can mean you have many cholesterol-depleted particles—still atherogenic—often seen with insulin resistance, high triglycerides, or genetic lipid patterns.
Why particle size and subfractions matter
Small, dense LDL patterns tend to travel with higher triglycerides, lower HDL-C, and insulin resistance. Particle size is not usually the primary treatment target by itself, but it can be a useful clue about the metabolic environment driving your lipid profile.
Why this is a panel (not one test)
No single lipid marker answers every question. Particle metrics, triglycerides, HDL measures, and ratios often need to be read together. This panel is built to show the pattern so you can avoid overreacting to one number.
What do my panel results mean?
Lower-risk patterns across the panel
A generally favorable pattern is when atherogenic particle markers are low (for example, ApoB and/or LDL-P are low), triglycerides are not elevated, and HDL-related markers are supportive (often higher HDL-C and/or healthier HDL particle measures). LDL-C may be low or moderate, but the key is that particle burden is not high. In this pattern, ratios such as triglycerides-to-HDL-C and non-HDL-C often look reassuring, suggesting fewer triglyceride-rich remnants and less metabolic strain.
More optimal, internally consistent results
An “optimal” panel is internally consistent: LDL-C, non-HDL-C, ApoB/LDL-P, and triglyceride-rich markers all point in the same direction. If LDL-C is modest and ApoB/LDL-P is also modest, that usually supports a lower atherogenic particle load. If triglycerides are low-to-moderate and HDL markers are supportive, it often suggests better insulin sensitivity and fewer remnant particles. Your clinician may still individualize targets based on age, blood pressure, diabetes status, smoking history, and family history.
Higher-risk patterns that often deserve follow-up
A higher-concern pattern is when ApoB and/or LDL-P is elevated (meaning more atherogenic particles), especially if non-HDL-C is also high. Another common higher-risk pattern is elevated triglycerides with lower HDL-C and a shift toward smaller LDL particles, which can signal insulin resistance and more remnant lipoproteins. Discordance matters: if LDL-C is not very high but ApoB/LDL-P is high, you may still have a meaningful particle burden. These patterns are often actionable with lifestyle changes, weight loss when appropriate, and/or medication, but the right plan depends on your full risk profile.
Factors that influence advanced lipid and fractionation results
Recent diet changes (especially carbohydrate intake, alcohol, and saturated fat), weight loss or gain, and training volume can shift triglycerides, LDL-C, and particle measures over weeks to months. Thyroid status, kidney disease, liver health, menopause, and pregnancy can also affect lipids. Medications (statins, hormone therapy, retinoids, some HIV therapies, atypical antipsychotics) and supplements can change LDL-C, triglycerides, and particle markers. Because methods differ by lab, it is best to trend results using the same panel and lab method when possible, and to interpret the full pattern rather than chasing a single “perfect” number.

Frequently Asked Questions
Do I need to fast for this panel?
Fasting is often recommended for the cleanest interpretation of triglycerides and triglyceride-rich lipoproteins, which can influence particle patterns and calculated values. If you did not fast, your results can still be useful, but discuss context (meal timing, alcohol, and recent exercise) when interpreting triglycerides and remnant-related markers.
What is the difference between LDL-C and ApoB?
LDL-C estimates how much cholesterol is carried inside LDL particles. ApoB reflects the number of atherogenic particles (LDL, VLDL remnants, and related particles) because each typically carries one ApoB molecule. You can have normal LDL-C but high ApoB if you have many cholesterol-poor particles.
If my LDL-C is high but ApoB is not, should I worry?
This is called discordance. It can happen when LDL particles are larger and carry more cholesterol per particle. It may be less concerning than when ApoB is high, but it is not automatically “safe.” Your overall risk depends on your age, blood pressure, diabetes status, family history, smoking, and sometimes additional tests (like Lp(a) or coronary calcium).
How soon should I repeat this panel after changing my diet or starting a statin?
Many lipid changes show up within 4–12 weeks, but the best timing depends on what you changed and how stable your routine is. If you are making a major diet shift or starting/changing medication, repeating around 8–12 weeks is a common interval to see a clearer new baseline. Your clinician may recommend a different schedule based on your risk level.
Is particle size more important than particle number?
For most people, particle number (ApoB and/or LDL-P) is the more direct marker of atherogenic particle burden. Particle size can provide helpful metabolic context—small, dense patterns often travel with higher triglycerides and insulin resistance—but size alone is usually not the primary treatment target.
Should I order this panel or a broader heart health panel?
This baseline fractionation panel is a strong starting point if your main question is LDL-C vs ApoB/particle metrics and how diet or therapy is affecting your lipid pattern. If you also want a fuller risk model—especially if you have strong family history, premature cardiovascular disease in relatives, or unexplained risk—consider a broader panel that includes lipoprotein(a) and inflammatory markers, and discuss whether imaging (like coronary artery calcium scoring) is appropriate.
