Summary of Patient Blood Volume Collection.

	All lancing eventsa	One lancing eventb	Repeat lancing eventc
No. of patients	64	53	11
No. of fingersticks	512	424	88
Blood volume, µL
Mean ± standard deviation	3.1 ± 2.1	3.1 ± 2.0	2.9 ± 2.4
Median	2.7	2.7	2.3

Each patient performed a minimum of 8 fingersticks (lancing events). Eleven patients required second lancing attempts to express ≥0.3 µL. Volume data were recorded only for the second fingerstick attempt in these patients.

^aThe mean blood volume per patient was used to calculate the mean and median blood volume across all 64 patients.

^bMean and median blood volume calculated using all 424 fingersticks.

^cMean and median blood volume calculated using all 88 fingersticks.
