giving blood

They are just very, very careful.

Once the marrow transplantation process has begun, if anything happened to the donor, it would already be too late for the recipient.

Lower HCT and HGB??

My last blood test showed lower levels. My HGB was 14.7(13.5-17.5) and HCT was 43.2(41-53). This was BEFORE I started HRT. I know endurance athletes try to get their HCT into the 50's for endurance purposes, but is a lower end number healthier than a higher end number?
