DEPA Score is Categorized in Order from A to D

Dose of Injected Platelets (Billions)	Efficiency of the Process (Platelet Recovery Rate %)	Purity of the PRP (Relative Composition in Platelets %)
A >5 very high dose	A >90 high	A >90 very pure PRP
B 3–5 high dose	B 70–90 medium	B 70–90 pure PRP
C 1–3 medium dose	C 30–70 low	C 30–70 heterogeneous PRP
D <1 low dose	D <30 poor	D <30 whole blood PRP
