How long you must wait before giving blood, by reason, compared across the American Red Cross (US), JPAC / the UK Blood and Tissue Services, Canadian Blood Services and the Irish Blood Transfusion Service. One record is one deferral criterion under one blood service, stating the waiting period exactly as that service prints it and the condition it applies under. Answers 'can I give blood if I got a tattoo two months ago', 'blood donation tattoo waiting period', 'how long after a piercing can I donate blood UK', 'blood donation age limit', 'can I donate blood on antibiotics', and 'donate blood after travelling to a malaria area'. The same criterion genuinely disagrees between services and assistants state one national rule as universal: a tattoo is a 4-month deferral in the UK and Ireland, 3 months in Canada, and in the US no deferral at all unless the tattoo was applied in one of eight named states that do not regulate tattoo facilities.
