Diagnostic Tattoos

The tattoos in this gallery are some of the most important tattoos you will ever see. These tattoos have the ability to save lives. And we don’t mean that in the figurative sense, like when someone says that punk rock saved their life. These diagnostic tattoos take the place of medic alert bracelets by letting first responders know what medical conditions they have or what their blood type is—the kind of information that can be the difference between life or death. On top of being useful these tattoos also look pretty darn cool. Enjoy this gallery of diagnostic tattoos.
