β-Thromboglobulin
proteinβ-Thromboglobulin is released during platelet activation and aggregation, marking the initiation of thrombotic cascade in acute MI.

RationalePlatelet α-granule release marker; direct platelet activation indicator.
Druggability
Not assessed (no mapped human gene target).

Non-Type-I axis panel
Does this marker also move in each non-Type-I setting? mag 0–3; higher means less Type-I-specific. n/a = no evidence retrieved, which is not the same as no change.
No non-Type-I axis evidence retrieved.
Tier: light (literature co-occurrence proxy — lower confidence). See the discrimination table for all markers.
Assay & specimen
Class-level default (no specific cleared assay)— generic method inferred from analyte class; confirm against a specific product insert before use.
