Background and Aims Eosinophilia may be associated with parasitic infection. To our knowledge the predictive value of eosinophilia has not been determined in internationally adopted children (IAC).
Methods Eosinophilia definition: absolute count ≥ 450/µl. Eosinophil counts were available in 285/314 IAC seen between 01/01/2008 and 31/03/20012. Feces and serological examinations for Strongyloides and Schistosoma were done in all children. We calculated the positive predictive value, negative predictive value and likelihood ratios of eosinophilia ≥ 450/µl for all parasites, solely pathogenic and solely tissue invading parasites in all 285 and 197 Ethiopian children.
Conclusion In this population the predictive value of eosinophilia is weak for parasitic infection.
