We analyzed the predonation tests and the characteristics of plateletpheresis of the candidates and donors during 18 month at Korea University Guro Hospital from 1993 to 1995. Among the 810 candidates tested for predonation tests, 115(14.2%) candidates were deferred due to incompatible factors. The most common incompatible factor is elevated alanine aminotransferase(4.6%, ALT > 64 Iu) followed by incompatible ABO discrepancy (4.1%), positive HBsAg(3.3%), low platelet count(2.2%). 43.1 percent of the platelet donation candidates were processed plateletpheresis. 43(18%) of prospectively reviewed 240 plateletpheresis donors were relatives of the recipients. The percent of redonation was only 14% and its mean interval was 11.4 days. The result showed the plateletpheresis candidates have the relatively safety compared to that of the directed donation, social support of plateletpheresis donation program is strongly needed because of low redonation rate and characteristics of plateletpheresis donation.
