I have had a couple of friends attempt to donate blood recently who were turned away because the machines weren’t able to draw from them.
Tubing issues were blamed first.
Eventually, the staff told them they couldn’t donate because the flow was being blocked by clots.
In both arms.
These people are all under the age of 35, by the way. And were under the impression they had no health issues.
I'm curious about Rh- stuff. Particularly, I'd like to know why they can't be cloned. Do you have a link?
There are many links. And there are many links that are currently trying to say that’s not true. It has to do with the D Antigen. Why negatives can’t be cloned. Basically the protein is needed, and negatives don’t have the monkey protein
