HDL Particle Number levels: what's normal, high and low
The actual count of HDL particles. Higher counts are associated with lower cardiovascular risk.

The short answer
HDL Particle Number is measured with a standard blood draw after an 8–12 hour fast. A typical reference range is 30.5 – 50.0 umol/L. At TestWell it's $70.99 all-in as Advanced Cholesterol Particle Test (NMR), results in 3–5 business days, drawn at Labcorp. An out-of-range result is a prompt to look closer, not a diagnosis.

HDL Particle Number Reference Range
These are the typical adult reference ranges used by major US labs. Your report will include the specific range used by the lab that processed your sample.
| Population | Range |
|---|---|
| age 18+ | 30.5 – 50.0 umol/L |
Reference ranges are educational. Always interpret your result with the specific range printed on your lab report and discuss anything outside the range with a clinician.
How do you get a HDL Particle Number test?
Order online, a licensed physician reviews the requisition, and you walk into a nearby lab for the draw. HDL Particle Number is available on its own or inside these panels — panels cost less per marker when you want the fuller picture.
| Option | Includes | Price |
|---|---|---|
| Advanced Cholesterol Particle Test (NMR) | This marker only | $70.99 |
Quest vs. Labcorp for HDL Particle Number: which lab should you pick?
Both are CLIA-certified national labs and the result is clinically equivalent, so pick whichever location is closer. Your report will print that lab's own reference range, which can differ slightly from the table above.
| Lab | Available | Price |
|---|---|---|
| Quest Diagnostics | No | — |
| Labcorp | Yes | $70.99 |
| BioReference (NY & NJ) | No | — |
