[Serology of typhoid fever in children. I. Capillary flocculation- agglutination. Its specificity in an asymptomatic population and its utility at a pediatric emergency service].
Using a capillary flocculation technique we evaluated serum samples of asymptomatic children for typhoid fever serology. Thirty one (5.16%) of the 600 serum samples tested were positive for a specificity of 95%. To evaluate the sensitivity of the test, serum samples from 36 children with proven typhoid fever and a similar number of control patients were evaluated. The sensitivity of the capillary flocculation test in this group was 100%. The test compared favorably with the Ruiz Castañeda serologic test for typhoid fever.
