摘要

Recently, the Chinese new standard GB 18467-2011 Health examination criteria of blood donors was put in practice from 1 July 2012. This new version made some amendments, such as the health consulting, donation intervals and volume. For the plasma alanine transaminase (ALT) screening test, requirements changed from <40 IUL~-1 to 'Meets related requirements'.There are still some controversies about whether it is suitable or even necessary for donor blood ALT screening since the 1980s (Silverstein et al., 1984; Khedmat et al., 2007). Owing to the low specificity of ALT activity and the application of nucleic acid test (NAT), the ALT screening of blood donors seems valueless. But in China and some European countries, it is recommended or even required by law (Brinkmann et al., 2003). Usually, the upper limit of ALT activity for blood donors are determined according to the upper limit of the reference intervals for normal person (from 1-5 to 3-0 times) (Brinkmann et al., 2003). In our department, for the old version of GB 18467-2001 required ALT < 40IUL~-1, just fit the upper limit of the reference interval which we used to make it as the cut-off value for blood donor screening.
