What finger should i use when i do a fingerstick test?

Finger stick: You can use any finger but you have better luck getting enough blood if you use the index or middle fingers as they have larger pads and larger number of capillaries.

Fingersticks: You can do a bloodstick on any finger. Some people avoid using their thumbs since these are frequently used digits - if there was any associated pain. Some avoid the little finger due to thinness of skin. The World Health Organization recommends using the ring or middle fingers. It is better to test on the side rather than the tip of the finger. Rotate the fingers that you do the sticks on.
