Donating blood is not bad. Once in six months is good. It shouldn't be done any sooner if not needed.

The normal interval between whole blood donations is 16 weeks (minimum 12 weeks) but no more than three donations 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. Donors giving double red cell donations by apheresis must have a pre-donation Hb concentration of 140 g/L and the minimum interval between donations is 26 weeks. Donors can give platelets or plasma by apheresis on a cell separator with a maximum of 24 procedures in 12 months. The minimum interval between donations is 2 weeks and plasma donors are limited to 15 litres a year.
