Pemeriksaan yang paling berguna adalah agregometri trombosit yangmengukur
penurunan serapan cahaya dalam plasma kaya trombosit sejalan dengan agregasi
trombosite.
e.Uji terhadap fibrinolisis
Meningkatnya kadar activator plasminogen yang bersirkulasi dapat dideteksi dengan
dengan adanya pemendekan masa lisis bekuan euglobulin.
