I don't know about
the Red Cross criteria, but I just checked into the possiblity of donating blood through INOVA, a local blood bank. It clearly states right on front of the brochure that any type of AI disease renders the individual disqualified. Not sure why, but perhaps it relates to the drugs we typically take. Although the drugs that I take (mtx and enbrel) are not listed as disqualifying.
