Cost estimates for conventional identification of blood culture isolates in three scenarios^a versus MALDI-TOF Sepsityper identification^b

Conventional ID scenario	Cost (U.S. dollars)/positive culture
	Avg	Sepsityper	Conventional ID for MS failurec	Net
Low cost	1.58	5.15	0.07	3.64
High cost	5.50	5.15	0.07	−0.28d
Best estimate	1.98	5.15	0.07	3.24

^aLow cost, high cost, and best estimate. See text for details.

^bEstimates assume a typical distribution of isolates (see Table 1).

^cAssumes 14.8% failure to identify with Sepsityper and cost of conventional identification is $0.50 per failed identification. See methods for details.

^dNet savings.
