Cardio IQ Lp-PLA2 Activity Test
The Cardio IQ Lp-PLA2 Activity test measures the activity of Lp-PLA2, an enzyme associated with inflammation in blood vessels. Clinicians use it as one input in cardiovascular risk assessment, interpreted alongside a person's history, lifestyle, and other markers rather than on its own.
About this test
Lipoprotein-associated phospholipase A2, usually shortened to Lp-PLA2, is an enzyme that clinicians connect specifically to inflammation within the walls of blood vessels. Unlike a broad, whole-body inflammation marker, Lp-PLA2 is thought to reflect vascular inflammation more directly, which is why it appears in advanced cardiovascular risk conversations. The activity version of the test looks at how active the enzyme is in the blood.
The Cardio IQ Lp-PLA2 Activity test is done with a simple blood draw at a patient service center. A phlebotomist collects a sample from a vein, usually in the arm, and the sample goes to the laboratory. People follow any preparation instructions their ordering clinician provides. Results are read by a clinician in the context of history, lifestyle, and any other cardiovascular markers ordered alongside it.
Who commonly orders it
People who order this test are often exploring cardiovascular risk in more depth than a standard panel provides, frequently under the guidance of a clinician. It is an advanced marker rather than a routine first look, so it tends to come up when someone wants additional context — for example, when a clinician is weighing vascular inflammation as one factor among several, or when earlier results or family history have prompted a closer look. Some include it as part of a wider advanced cardiovascular workup, while others add it specifically for its focus on vascular inflammation.
What this test looks at
The test measures how active the Lp-PLA2 enzyme is in the blood. Because clinicians associate this enzyme with inflammation in the vessel wall specifically, it is often described as a vascular-inflammation marker rather than a general one. That focus is what distinguishes it from broader inflammation tests that reflect the whole body.
It also helps to remember what Lp-PLA2 is not: it is not a stand-alone verdict on cardiovascular health, and it is not something a person interprets alone. It is one advanced marker among several, which is why a single result is read as a piece of a larger risk picture rather than a conclusion.
How it's often used alongside other tests
Lp-PLA2 activity is generally ordered as part of an advanced cardiovascular evaluation rather than in isolation. A clinician often reads it alongside lipid markers such as LDL and HDL cholesterol, advanced particle markers like ApoB or Lp(a), and general inflammation markers. Because vascular inflammation is only one thread in cardiovascular risk, seeing it together with the others gives a clinician far more context than any single marker can on its own.
What to expect at your visit
No appointment is needed for the draw itself. People can visit a patient service center during open hours, where a phlebotomist collects a small sample from a vein in the arm, and most visits wrap up in a few minutes. Once the laboratory completes its analysis, results are posted to the account, where they can be reviewed and shared with a clinician.

Frequently asked questions
What does the Lp-PLA2 Activity test measure?+–
It measures the activity of Lp-PLA2, an enzyme clinicians associate with inflammation in the walls of blood vessels. It is used as one input in cardiovascular risk assessment.
How is Lp-PLA2 different from a general inflammation marker?+–
General inflammation markers reflect inflammation anywhere in the body, while Lp-PLA2 is associated more specifically with vascular inflammation. Clinicians consider that focus when deciding whether it adds useful context.
Is this an advanced or a routine test?+–
It is an advanced cardiovascular marker rather than a routine first look. It tends to come up when someone wants more depth than a standard panel provides, often under a clinician's guidance.
How is the sample collected?+–
Through a routine blood draw at a patient service center. A phlebotomist takes a small sample from a vein in the arm and sends it to the laboratory.
Can this test alone assess my cardiovascular risk?+–
No single marker establishes cardiovascular risk on its own. A clinician reads Lp-PLA2 activity together with other markers, history, and lifestyle to build a fuller picture.
Can I get the Cardio IQ Lp-PLA2 Activity test without a doctor's visit or insurance?+–
Yes. The $109 cash price includes an independent physician's order, so no appointment or referral is needed, and insurance is never involved.
