Table 2. Time savings achieved for model microbes using autofluorescent detection.

	Time to detection (hr)
	autofluorescence1 , 2	visual3
C. albicans	2.2±0.2	22
E. coli	3.1±0.1	8.5
B. diminuta	9.8±0.2	22

¹Time at which 50% of the autofluorescent microcolonies were first detected by prototype software.

²Ranges represent the 95% confidence interval.

³Time at which colonies become visible to the naked eye (0.5 mm in diameter).
