P-selectin+ microparticles

complex

P-selectin+ microparticles are released during platelet activation and mediate leukocyte adhesion at sites of arterial injury.

Pathway placement

Cascade stepPlatelet adhesion & activation

Confidencehigh

RationaleP-selectin+ microparticles mark platelet activation and platelet–leukocyte interaction; predict cardiovascular events.

Type I vs Type II discrimination

ScoresLow-confidence (proxy)

R — rupture / Type-I

C — confounder / Type-II

A — assay feasibility

E — evidence strength

T1DI (composite)

Specificity differential (R−C)+27.5

Confounder panel (Type-II drivers)

No confounder evidence retrieved.

Tier: light (literature co-occurrence proxy — lower confidence). See the discrimination table for all markers.

Class-level default (no specific cleared assay)— generic method inferred from analyte class; confirm against a specific product insert before use.
