RESUMEN
<p><b>OBJECTIVE</b>To improve the existing serological early diagnosis method of nasopharyngeal carcinoma by improve the detection sensitivity.</p><p><b>METHODS</b>The samples of 294 serum specimen from the prevention and treatment of nasopharyngeal cancer model base, involving 106 serum specimen from the patients suffering from nasopharyngeal cancer and 188 from the healthy testers. IgA/VCA antibody and IgA/EA antibody of the serums are tested by Streptavidin-biotin-antibody immunoenzymatic test and normal traditional enzyme methods, SPSS statistical software is used to analyse the test results with chi2 test and t test.</p><p><b>RESULTS</b>Referring to 106 patients, the sera antibody positive rate tested by Streptavidin-biotin-antibody immunoenzymatic test method is obviously higher than that tested by traditional method; and the t test result of the GMT has significant difference in the two method.</p><p><b>CONCLUSION</b>The modified method can improve the sensitivity of serology testing, ensure the specificity of test results, at the same time, improve the detection rate of nasopharyngeal carcinoma, so it can be applied to the early screen work of nasopharyngeal carcinoma.</p>
