Recruitment of voluntary non-remunerated apheresis donors: the second five years' experience in Shenzhen.

The voluntary non-remunerated blood donation campaign in Shenzhen, China, was launched in 1993 and the smooth change from paid donors to unpaid took only a decade. In the first half the volunteer donation system and a sufficient blood supply was promoted and this paved the way for further development in the second half during which the non-remunerated donation system became substantial and integral due to recruitment for plateletapheresis and peripheral stem cells donation as well as whole blood donations. Ninety percent of the donors registered for plateletapheresis do donate and none of the twenty-three non-related donors with matched HLA genotypes broke their promise to donate their peripheral stem cells.
