PLAC Test Blood Test For Heart Disease & Stroke Risk

Measures lipoprotein-associated phospholipase A2 (Lp-PLA2), a blood marker associated with vascular inflammation. Its role and clinical value depend on the assay and patient context; it does not image plaque, diagnose cardiovascular disease or replace standard risk assessment.

What this test measures

Lipoprotein-associated phospholipase A2 (Lp-PLA2)

A blood marker associated with vascular inflammation; it does not image plaque or diagnose cardiovascular disease. A markedly raised result can support assessment of pancreatic inflammation when symptoms fit, but smaller changes occur for several pancreatic and non-pancreatic reasons.

How clinicians use this test

Clinicians may use Lp-PLA2 as an additional cardiovascular-risk marker in selected situations. It does not image arterial plaque and is not used alone to diagnose coronary disease, heart attack or stroke.

Is this the right test for you?

This may suit someone who specifically wants to check Lipoprotein-associated phospholipase A2 (Lp-PLA2), or repeat the marker(s) as part of an established monitoring plan. It is a focused test and may not include related markers needed to explain an abnormal result. The test should not delay assessment of persistent or worsening symptoms.

Preparation and collection

Return the sample on the same day it is collected. Do not post over weekends or bank holidays.

Understanding your result

The laboratory will report Lipoprotein-associated phospholipase A2 (Lp-PLA2) with an assay-specific reference range, threshold or qualitative interpretation. Read the biomarker explanation above for common reasons a result may be high, low, detected or reactive, then use the laboratory comment and clinical context to decide whether repeat or follow-up testing is needed.

Your results and next steps

Review Lipoprotein-associated phospholipase A2 (Lp-PLA2) against the reference range and laboratory comment, then consider whether the pattern fits your symptoms, medicines and reason for testing. Share a concerning or unexpected result with a clinician before changing treatment, supplements or diet.

Limitations

The result is a snapshot from one sample. It cannot diagnose a condition on its own; values inside or outside a reference range require clinical context.

When to get medical help

Do not wait for a home-test result if you feel seriously unwell. Call 999 for a life-threatening emergency, or use NHS 111 when you need urgent advice and are unsure what to do.
