The indirect hemagglutination test for onchocerciasis performed with blood collected on filter paper. 1978

T Ikeda, and I Tada, and Y Aoki

In Guatemala, an indirect hemagglutination (IHA) test for onchocerciasis, performed with a crude saline extract of Onchocerca volvulus and blood samples taken on filter paper, showed a high level of sensitivity and specificity. IHA titers of blood samples from the ear lobe taken on filter paper and of sera obtained by venipuncture showed a high correlation.
