 NAMASKARA NANISRO DOCTOR MALLIKARJUAN KALISHETTI ANTA I'm a consultant hematologist, hematoconcologist and bone marrow transplant physician at Manipal Hospital, Bangalore So, this issue is very common in our donors So, largely there are no short term or long term risks to the donor So, if you don't like the donor, the risk of life threatening is not the majority of the cases Many times, we collect peripheral blood stem cells It is as good as giving platelets, giving blood So, it is not a surgical procedure So, we don't do any surgery in the stem cell collection So, if your blood is an aphorosis procedure, we collect the stem cells in the machine We return the remaining components of your blood So, that is peripheral stem cell collection If we have to collect stem cells from the bone marrow then donors will take them to operation theatre and give them general anesthesia So, the stem cells will come out of the bone marrow So, after the procedure, it will be no more than 5 days So, it will rarely drop the hemoglobin So, in a nutshell, there are no short term or long term risks for the donor
