Advanced lipid panels

Diagnostics & Exams

Advanced lipid panels go far beyond the standard cholesterol test by directly measuring the particles that actually drive plaque formation. In addition to total cholesterol, LDL, HDL, and triglycerides, the panel quantifies LDL particle number (LDL-P), particle size, ApoB (the protein on every atherogenic particle), and Lp(a) (a genetically determined risk marker that standard panels miss entirely). Two patients with identical LDL cholesterol can have very different particle counts — and very different cardiovascular risk. Advanced testing is especially valuable for patients with a family history of premature heart disease, metabolic syndrome, an unexplained calcium score, or recurrent events despite a "controlled" standard panel.

What's Included

  • LDL particle number (LDL-P) and size analysis
  • ApoB quantification
  • Lp(a) measurement (recommended at least once in every adult's life)
  • HDL functionality and subfraction assessment
  • Triglyceride-rich remnant cholesterol measurement
  • Personal walkthrough of each marker with Dr. Kedan
  • Individualized lipid-lowering plan based on the full picture

How It's Performed

Advanced lipid testing is performed in our Beverly Hills office as a single venous blood draw — the same experience as any routine lab. The complexity is in the laboratory analysis, not the collection. The draw itself takes only a few minutes, and the specimen is sent to a reference lab for the specialized particle assays.

How to Prepare

  • Fast for 9 to 12 hours before the draw for the most accurate triglyceride measurement.
  • Water is encouraged — it makes the draw easier.
  • Take most prescription medications as usual unless Dr. Kedan directs otherwise.
  • Avoid alcohol for 24 hours before the test.
  • Bring a list of current supplements and prior lipid results for comparison.

What to Expect After

There is no recovery — you can eat, drive, and resume activity immediately after the draw. Results typically return within several business days. Dr. Kedan reviews every panel personally and schedules a focused follow-up to walk through what each marker means for your specific risk and treatment plan. Patients with a normal LDL but a high LDL-P, ApoB, or Lp(a) often need more aggressive therapy than a standard panel would suggest, while some patients with a borderline LDL turn out to have a benign profile and can avoid medication entirely.

Indications

  • Family history of premature coronary disease or stroke
  • Unusually low HDL or elevated triglycerides
  • Metabolic syndrome or pre-diabetes
  • Elevated CT coronary calcium score with normal standard lipids
  • Recurrent cardiovascular events despite controlled LDL
  • Statin intolerance or partial response
  • Any adult who has never had Lp(a) measured

Common Questions

Frequently Asked Questions

What is an advanced lipid panel?
A standard cholesterol test reports four numbers — total cholesterol, LDL, HDL, and triglycerides. An advanced lipid panel adds detailed measurements of the actual particles that carry cholesterol in the bloodstream: LDL particle number (LDL-P), particle size, ApoB (the protein on every atherogenic particle), and Lp(a) (a genetically determined risk marker that standard panels miss entirely). The result is a far more accurate read on cardiovascular risk.
Why does particle number matter more than LDL cholesterol?
It's the number of atherogenic particles colliding with the artery wall — not the total cholesterol cargo inside them — that drives plaque formation. Two patients with the same LDL cholesterol can have very different particle counts, and the one with more particles is at higher risk. ApoB and LDL-P both measure that particle burden directly, which is why they often outperform standard LDL as a treatment target.
Why would Dr. Kedan order advanced lipid testing?
Common reasons include a family history of premature heart disease, an unusually low or high HDL, elevated triglycerides, metabolic syndrome or pre-diabetes, an unexplained calcium score elevation, recurrent cardiovascular events despite "controlled" LDL on a standard panel, and any patient wanting a sharper picture of risk before deciding on statin or other lipid-lowering therapy.
What is Lp(a) and why test for it?
Lp(a) is a cholesterol-carrying particle whose level is determined largely by genetics. Elevated Lp(a) independently raises the risk of heart attack, stroke, and aortic valve disease — and because it doesn't respond meaningfully to diet or standard statins, you'd never know it was elevated without specifically measuring it. Every adult should know their Lp(a) at least once in their life, since the level rarely changes thereafter.
How do I prepare for the test?
A 9–12 hour fast is generally recommended for the most accurate triglyceride measurement, though some advanced panels can be drawn non-fasting. Water is fine, and most medications can be taken as usual. Dr. Kedan will give you specific guidance based on which markers are being measured.
Is it just a blood draw?
Yes. A single venous blood draw — same experience as any routine lab. There's no special procedure, no scan, no recovery time. The complexity is in the analysis, not the collection.
When will I get the results?
Advanced lipid panels typically come back within several business days, depending on the laboratory. Dr. Kedan reviews every result personally and walks you through what each marker means for your specific risk and treatment plan — often during a focused follow-up visit so the conversation isn't rushed.
Will the results change my treatment?
Often, yes. Patients with a normal LDL but a high LDL-P, ApoB, or Lp(a) frequently need more aggressive therapy than a standard panel would suggest. Conversely, some patients with a borderline LDL turn out to have a benign particle profile and can avoid medication. Personalized lipid management — rather than treating to a single number — is where advanced testing earns its keep.
Are there any risks?
Only the standard minor risks of any blood draw: brief discomfort at the needle site, occasional small bruise. There is no risk from the testing itself.
Is advanced lipid testing covered by insurance?
Coverage varies considerably by carrier and by which markers are ordered; Lp(a) and ApoB are increasingly covered, while detailed particle analyses sometimes are not. Cardiolucent does not accept Medicare or insurance for office visits and bills patients directly; we provide a detailed superbill for out-of-network reimbursement.
