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.
When donating platelets, the whole process takes approximately two hours. The blood donation itself usually takes 5-10 minutes for whole blood, 25 minutes for double red cell donation and 60-90 minutes for platelet donation.hey can take two weeks or longer to fully return to normal. You can donate platelets (apheresis donation) every two weeks â up to 24 times in 12 months. Platelet and plasma components are regenerated in the body more quickly than red cells. Platelets will return to normal levels within 24-48 hours of donating.
