Fluorescent Antibody Staining as a Measure of Malarial Antibody

Abstract

The indirect fluorescent antibody method was used to measure the level of antibody to malaria in a sample of the semi-immune population of Liberia. High titers were obtained in sera from adults and placental cord blood. Young children had lower titers and sera from non-immune Europeans were negative. The test was also successfully carried out using blood eluted from filter papers.
