Lp-PLA2 Activity
An enzyme produced by inflammatory cells inside arterial plaque — a marker of vascular-specific inflammation rather than general body-wide inflammation.
hs-CRP tells you there's inflammation somewhere; Lp-PLA2 tells you it's happening in your artery walls. That specificity makes it useful for refining risk when ApoB is borderline or family history is strong.
Optimal ranges, root causes, and the complete correction protocol — nutrition, supplements, lifestyle, hormones and peptides — plus 100+ other markers.

On its own, one marker is a data point. These panels include Lp-PLA2 Activity plus the markers that make it interpretable — each names every test, why it is on the list, and loads the whole set into your cart in one click at 10% off.
includes this + 8 more markers — Anyone over 30, anyone with a family history of early heart disease, or anyone who's been told their cholesterol is 'fine' and wants to know what that actually means.
includes this + 9 more markers — Persistent aches, slow recovery, autoimmune history, high cardiovascular risk, or a raised CRP that nobody explained.
Would you feel it? Symptoms Lp-PLA2 Activity helps explain
People rarely search for a marker — they search for how they feel. These are the complaints where this marker is worth checking, and whether it is a first-line test or a follow-up once the obvious causes are ruled out.
Why your Lp-PLA2 Activity might be wrong
Most abnormal results are interference, not disease. These are the things that measurably move this specific marker — check them before you change anything. Each one says whether the number is wrong and should be repeated, badly timed and should be redrawn, or real with a cause worth explaining.
This is an acute-phase reactant — it moves substantially during any infection, injury or inflammatory episode, and the change has nothing to do with your baseline.
Wait two weeks after any illness, vaccination or injury before drawing or interpreting.
Lower Lp-PLA2 alongside lipids, so a treated value understates untreated vascular inflammation.
Interpret with treatment status in mind.
What Lp-PLA2 Activity means in combination
A single marker tells you a little. Combinations tell you the story — these are the named patterns this marker takes part in, and what each one points at.
Residual inflammatory risk. Plaque forms and destabilises through inflammation as well as lipids, so hitting an ApoB target while CRP stays high leaves a meaningful part of the risk untouched.
Rule out the obvious first — CRP rises with any infection, injury or hard training, so retest rested and well. If it stays up: sleep, visceral fat, periodontal disease, gut health, omega-3s. Persistent unexplained elevation deserves a real workup.
