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.
The plasma from your donation is replaced within about 24 hours. Red cells need about four to six weeks for complete replacement. Thatâs why at least eight weeks are required between whole blood donations.our gift of blood may help up to three people. Donated red blood cells do not last forever. They have a shelf-life of up to 42 days. A healthy donor may donate every 56 days.
