It is recommended to keep a gap of 12 weeks for men and 16 weeks for women between the blood donations.

                                   If there is high number of platelet count in the blood, these may be donated directly as the normal blood donated.

More need of blood donation
It has been researched that in developed countries there are large number of people who could donate blood. But, merely 4% of them actually donate. This percentage is very low keeping in view the blood needs. In developed countries about 7000 blood transfusions are carried daily. Therefore the need could not be fulfilled with the existing stock of blood. Another problem for fulfilling the blood needs is that donated blood can’t be stored for a longer period of time, stock of blood is need to be refreshed continuously. We take the example of red blood cells; it has to be refreshed after every 35 days.
