Ensure the test strip code matches the code on the meter, insert the strip into the meter, obtain your blood sample, place the sample on the strip, and read your results, states OneTouch. Depending on when you're testing, you can take the sample from a fingertip, palm or arm.
Prior to pricking yourself with a lancet, wash the site with soap and water, and dry it completely, advises OneTouch. If the drawn blood spread across the skin instead of forming a drop, re-prick your skin to obtain another sample. When putting the blood onto the test strip, touch the test strip to the blood drop without touching your skin.
