Clinical value of the guanase screening test in donor blood for prevention of posttransfusional non‐A, non‐B hepatitis
Susumu Ito, Yasuhiro Tsuji, Naoyuki Kitagawa, Ishihara Akihiko, Jyoji Syundo, Yoshiyuki Tamura, Seiichiro Kishi, Hiroyoshi Mori – 1 March 1988 – We adopted an automated method for measuring guanase in donor blood and examined the incidence of posttransfusional non‐A, non‐B hepatitis when donor blood with high guanase activities was excluded. Sixty‐seven (2.4%) of 2,826 units were excluded from use in transfusion because they had guanase activities above 1.71 units per liter. Of 112 recipients, 8 (7%) developed posttransfusional non‐A, non‐B hepatitis.
