Why can't a tattooed person donate blood?
The American Red Cross require a 12-month waiting period after receiving a tattoo in an unregulated facility before a person can donate blood. This is due to the risk of hepatitis. Hepatitis is a type of liver inflammation. Why can't you give blood after a tattoo? You may not be able to donate if your ink is less than 3 months old. Giving blood after recently getting a tattoo can be dangerous.
