RT Journal A1 Godley LA, van Besien K T1 DOnor policies for stem cell transplantation—reply JF JAMA JO JAMA YR 2010 FD August 4 VO 304 IS 5 SP 524 OP 525 DO 10.1001/jama.2010.1073 UL http://dx.doi.org/10.1001/jama.2010.1073 AB In Reply: Mr Tischler raises an important issue surrounding the restrictions put forth by the NMDP for potential donors of HSCs. Although the NMDP health history questionnaire would seem to indicate linkage to the FDA policy on blood transfusion, this is unfortunately misleading. When an individual enters the NMDP system to register, one of the health questions asked (of men only) is “ . . . In the past 5 years have you had sex, even once with another male?” However, given the sensitive techniques for detection of HIV and other transmittable viruses, even this has become a controversial issue.
