In brief: With fingersticks

If the hands and fingers aren't clean and dry, home blood sugar readings may be inaccurate.
Sugar on the fingers could end up falsely elevating blood sugar. A concomitant venous sample in lab could demonstrate a discrepancy. Also, the meter may be inaccurate. Eating before a fasting blood sugar may raise the blood sugar in someone with diabetes because it would not be fasting anymore.
