Why is blood taken from the ring ring?

Reduce the risk of infection
Any perforation of the skin can lead to an infection. The internal shells of the thumb and ear are directly connected to the shells of the hand - if the infection enters it, it can quickly spread to the entire arm. And the shells of the remaining fingers are insulated, and even if an infection penetrate them at the time of the tap, it will be located for a while, allowing it to be removed quickly.

Pain pain
Due to the fact that this finger is the most “non functional” - the skin is thinner, which means it is easier and less painful to do a tap.

Quick healing
In comparison to other fingers, the ring finger moves less, the wound heals faster, which also reduces the risk of infection.
