Blood Screening for Influenza
نویسندگان
چکیده
Influenza viruses, including highly pathogenic avian influenza virus (H5N1), could threaten blood safety. We analyzed 10,272 blood donor samples with a minipool nucleic acid amplication technique. Analytical sensitivity of the method was 804 geq/mL and 444 geq/mL for generic influenza primers and influenza (H5N1) subtype-specific primers. This study demonstrates that such screening for influenza viruses is feasible.
