Why can't people with tattoos donate blood?
I see. Is there a certain amount of time a person with a tattoo has to wait before they can donate blood?
Yes, there is typically a waiting period that must be observed after getting a tattoo before a person can donate blood. This waiting period can vary from location to location, but it is usually around 12 months. However, some blood donation organizations may have more lenient waiting periods or no waiting period at all if certain conditions are met, such as if the tattoo was done at a licensed facility using sterile equipment.
