Median blood glucose levels measured by a portable analyzer under different experimental conditions in 10 subjects with normal glucose tolerance

Test condition	Fruit peeling	Hand washing	Alcohol swab	Orange (n = 10)	Grape (n = 10)	Kiwi (n = 10)

Overscaled data (high, >600 mg/dL) were converted to 600 mg/dL to calculate median blood glucose level. Data are indicated as median (interquartile range: 25–75%).
