In areas where tattooing is not as closely monitored, people are asked to wait for 12 months to give blood after getting a tattoo. This waiting period ensures that the donor is free of any potential blood-borne diseases which could have been passed on unsanitary equipment.
This is the most common type of donation, during which approximately a pint of 'whole blood' is given. The blood is separated into transfusable components â red cells, plasma, platelets and/or cryoprecipitated AHF. This type of blood donation usually takes about an hour, though the actual donation takes about 8-10 minutes. You are eligible to donate 'whole blood' every 56 days.
