title: [Post-transfusion hepatitis iin Chile: the reference parameters].
abstract: Most cases of post-transfusion hepatitis correspond to infection by non-A non-B virus. Indirect test (ALT elevation, anti-HBc titers) have been used to detect the presence of this virus. We screened 692 blood donors and health personnel, measuring anti-HBc (n = 572), HBs antigen (340), and ALT serum levels (190). Positive results were obtained for anti-HBc in 1.7% and HBs in 0%. ALT levels were 25 +/- 12 u/l in males and 18 +/- 14 in females (p < 0.01). ALT levels above 45 u/l were found in 6% of subjects. ALT levels were not related to anti-HBc positiveness nor to alcohol intake. The possible risk of posttransfusion hepatitis related to increased ALT levels remains to be clarified by specific markers.
