How do you take a blood sugar reading?
To take blood from the finger, the most common way to take blood sugar, a person pricks the area with a sharp, small lancet, which is a needle, and then puts the blood on a test strip, explains WebMD. The individual inserts the test strip into a special meter that reads the blood sugar level. Some meters store the information, and some can report the average blood sugar level over a period of time. Some models may also show graphs and charts with blood sugar information on them.
