Abstract

The ZstatFlu test(ZymeTx, USA) is a rapid detection kit for influenza types A and B virus. This test is based upon the reaction between viral neuraminidase from influenza viruses and chromogenic substrate. The positive specimen of influenza type A or B virus cleave the substrate and produce a blue colored product. The ZstatFlu was evaluated by a prototype viruses, isolated viruses and clinical specimens. At result, this kit was reactive for all human influenza type A and B virus. No cross reactivity was detected with other respiratory viruses, including parainfluenza type 1, 2, 3 and mumps viruses with neuraminidase activity. Throat swabs were used for the test. By comparison with cell culture and RT-PCR. The sensitivity and the specificity was 77.0% and 90.2% respectively. The ZstatFlu should be useful for the rapid diagnosis of influenza virus infection.
