donate blood

Post by kiekyon » Thu Mar 09, 2006 9:20 am

just wondering if donating blood would have harmful effect to the donor?

i mean isn't there a limit to the number of times out cells can divide?

As much as I know, there is a limit for donating blood. You can not donate like 5L of your blood. Or you can not donate every day. :)
Yes there is a limit for division. But note that blood cells continuesly die and the new ones are produced even if you don't donate.

"Red blood cells, white blood cells, and platelets grow from a single precursor cell, known as a hematopoietic stem cell. Remarkably, experiments have suggested that as few as 10 stem cells can, in four weeks, multiply into 30 trillion red blood cells, 30 billion white blood cells, and 1.2 trillion platelets—enough to replace every blood cell in the body." (from: http://encarta.msn.com/encyclopedia_761 ... d.html#p46 )
Looks good doesn't it? ;)

Too much donation will have harmful effects, in my opinion. But a few won't hurt.

EDIT: I've found something, you may be interested:

"Donation Intervals
Wait at least 8 weeks between whole blood (standard) donations.
Wait at least 3 days between plateletpheresis donations.
Wait at least 16 weeks between double red cell (automated) donations. "
