Lipoprotein Fractionation Panel (Ultracentrifugation)
A cholesterol breakdown that measures LDL directly instead of estimating it, useful when triglycerides are high.
Consider this test if:
- High or borderline triglycerides, where a calculated LDL becomes unreliable
- Building a cardiovascular baseline or rechecking after a diet, exercise, or statin change
- Family history of high cholesterol or early heart disease
- Sorting out metabolic syndrome alongside weight, blood pressure, or blood sugar concerns
- A prior calculated LDL looked inconsistent with the rest of your lipid results
- HSA/FSA eligible
- Results delivered to your dashboard · Reviewed by a real clinician
- Drawn at a CLIA/CAP-accredited lab near you ·
Pre-test considerations
Fast 9 to 12 hours before the draw, since triglycerides and the calculated VLDL rise sharply after eating. Water and prescription medications are fine. Results reflect recent diet and alcohol, so keep habits typical in the days before testing for a representative reading.

What this test is for
This panel reports total cholesterol, triglycerides, HDL, and LDL, and adds VLDL, the triglyceride-rich particles that carry fat through the blood. The distinguishing feature is method: ultracentrifugation physically separates the lipoprotein fractions, so LDL is measured directly rather than estimated by the Friedewald equation used in a standard lipid panel. That matters most when triglycerides are elevated or LDL runs low, the exact situations where the calculated value drifts off. High LDL and triglycerides raise cardiovascular risk, and the HDL-to-total ratio plus VLDL help flag metabolic syndrome and insulin resistance.
If your question is particle count rather than cholesterol mass, ApoB or the ion-mobility and NMR fractionation panels count atherogenic particles directly; this panel measures how much cholesterol each fraction carries.
Biomarkers tested
Includes 5 biomarkers
HDL cholesterol measures the fraction of cholesterol carried by particles that pull excess cholesterol out of artery walls and ferry it back to the liver for disposal, a process called reverse cholesterol transport. Low HDL removes less cholesterol from circulation and tracks with higher cardiovascular risk, often alongside high triglycerides, excess visceral fat, insulin resistance, or a sedentary lifestyle. Checking it alongside ApoB and triglycerides gives a fuller risk picture than total cholesterol alone, and it's a useful marker for tracking how exercise, weight loss, or alcohol reduction shift your lipid profile over time.

- Mass concentration
LDL carries cholesterol from your liver into circulation, and when it lingers too long it works its way into artery walls and seeds plaque. This measurement (serum/plasma LDL cholesterol by mass concentration) is the standard baseline for cardiovascular risk, useful for tracking against diet, exercise, statins, or other lipid-lowering strategies over time. High LDL usually shows up with no symptoms at all, which is exactly why people test it before it becomes a family history story instead of a data point.

- Mass concentration
Pre-beta lipoprotein is the older electrophoresis-based name for VLDL, the particle your liver packs with triglycerides to ship energy out to tissues. High levels flag triglyceride overload, often from excess carbs, alcohol, insulin resistance, or poorly controlled diabetes, and they add to the atherogenic particle burden that drives plaque buildup. This test has largely been replaced by direct triglyceride and lipid panel measurements, but it's still useful for baselining fat metabolism or cross-checking older lab results against current lipid patterns.

- Mass concentration
Total cholesterol adds up everything your blood carries: LDL, HDL, and a fraction of your triglycerides. It's a decent starting snapshot but a blunt one, since it can't tell you whether the load is mostly protective HDL or the LDL particles that drive plaque, which is why it's best read alongside ApoB or an LDL/HDL breakdown rather than on its own. Useful as a baseline cardiovascular check or to track how diet, weight change, or medication are shifting your lipid picture over time.
- Specimen
- Serum or plasma
- Measures
- Mass concentration
Triglycerides measure the fat circulating in your blood after your body packages up unused calories, mostly from carbs and alcohol, for storage. High levels signal that your liver is overwhelmed with fuel it can't burn, a pattern common with excess sugar, alcohol, weight gain, or insulin resistance, and one that drives cardiovascular risk independent of LDL. Pair it with fasting insulin and HDL to see the full metabolic picture, and track it when you cut sugar, alcohol, or refined carbs to see if the intervention is actually working.

Frequently asked questions
View all FAQsHow does pricing work?
Every test shows the member price next to the standard non-member price, so you can see what membership saves you. The member price is our cost, covering the lab and what it takes to run the service. It is never a profit on the test itself. Mito makes its money on the $9 membership, not on marking up your tests. Membership is $9 per month, and any applicable lab order or draw fee is itemized before you pay.
Where do I get tested?
Choose an available partner lab at checkout. If your cart contains multiple blood tests, Mito helps consolidate the eligible tests at one lab when possible. At-home kits and scans follow the collection or appointment process shown on their product page.
Is this eligible for HSA/FSA?
Yes. Eligible tests can be paid for with an HSA or FSA card at checkout.
When will I get my results?
Your results appear in your Mito dashboard after the laboratory completes processing. A clinician then reviews them before your analysis and personalized action plan are finalized. Timing varies by test, and specialty assays and at-home kits may take longer.
Do I need a physician's order?
No. Mito provides the laboratory order when one is required, so you do not need to arrange a separate physician visit before purchasing.
