Bone MArrow Donation

[DX Wombat]

This is a thought as I don't know the regs regarding flying, but here goes. Blood and plasma donors can give blood as much as every 12 weeks for blood. I think it is 6 weeks for Plasma but am not sure. A bone marrow donor is unlikely to find him/herself called upon very frequently - if ever in some cases. This is because bone marrow is far more accurately tissue-typed than blood and is therefore more closely matched to the recipients requirements. So closely, in fact, that even a parent may not provide a close enough match. So you are not likely to be called on very frequently but if you are called you may be the recipient's last chance. Good luck.
