Frequency of donation

The normal interval between whole blood donation is 16 weeks(minimum 12 weeks) but no more than three donatons a year are collected from female donors because of their more precarious iron status. Donors undergo a screening test for anaemia, usually the copper sulphate flotation test on a finger prick sample. The minimum pre-donation Hb concentration is 125 g/L for female donors and 135 g/L for males.
