[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.
