Platelet-derived microparticles
complexPlatelet-derived vesicles released during platelet activation that propagate tissue-factor-driven thrombus formation.
Pathway placement
Cascade stepPlatelet adhesion & activation
Confidencehigh
RationalePlatelet activation marker; triggers coagulation cascade; thrombotic driver in ACS.
Also acts inCoagulation / thrombus
Druggability
Not assessed (no mapped human gene target).
Type I vs Type II discrimination
ScoresLow-confidence (proxy)
R — rupture / Type-I71
C — confounder / Type-II52
A — assay feasibility58
E — evidence strength27
T1DI (composite)9
Specificity differential (R−C)+19.5
Confounder panel (Type-II drivers)
No confounder evidence retrieved.
Tier: light (literature co-occurrence proxy — lower confidence). See the discrimination table for all markers.
Assay & specimen

Specimen
Plasma (citrate for coagulation complexes)
Collection tube
Sodium citrate 3.2% (light blue-top) · K2/K3-EDTA (lavender-top)
Method / principle
