There are quite a number of questions asked in the screening process. Some of the basics that will prevent you from donating are noted below. It appears that it is the FDA who has placed a halt on donating if you lived abroad or visited during certain periods. Not noted on the list below is visiting New Orleans after Katrina passed through. I am uncertain as to the whys, but my guess is that there are still some unknowns on many diseases out and about, so it is easier to use an ounce of prevention rather than 15 pounds of symptom control.
I know that the screening process is different if donating platelets rather than red blood cells. However, on the mobile unit which comes to the Hospital, you cannot donate platelets only. They tried bringing that machine once, but it was not working well on the bus set-up.
