[Comparison and evaluation of enzyme-linked immunization assay kits with plague reduction neutralization test for detection of measles IgG antibody].

OBJECTIVE

To evaluate and comparison of 2 commercial ELISA kits (Vrion/Serion kit and IBL kit) which ELISA kit will be used in sero-epidemiological survey in China in 2006 by Plaque Reduction Neutralization Test (PRNT).

METHODS

52 serum panel which contain different levels of measles antibody were used.

RESULTS

The results showed that the sensitivity, PPV and accurate of Virion/Serion kit achieved highest score when taking PRNT as "gold standard". Virion/Serion kit showed good relationship with PRNT titer: the correlation coefficients are 0.878 (P<0.01). IBL kit get lower correlation coefficients 0.850 (P<0.01). The test value and mean of unit of serum antibody increased along with neutralizing titers increased.

CONCLUSION

The Virion/Serion kit is good in sensitivity and specificity. It has quantitative for single well. The kit is suitable for sera epidemiology survey to detection of automatic workstation in China.
