Each subject selected for the comparison evaluation will perform their own fingerstick and test on their subject device following device instructions. A trained technician will perform a fingerstick on the subject immediately after and perform the test on the same device. Separate results will be recorded by subject and technician. A trained technician will take another blood sample, within as short of a time as practicable, for a glucose assay on the YSI 2300 Stat Plus Glucose Analyzer.
