title: Whole blood collection on filter paper is an effective means of obtaining samples for human immunodeficiency virus antibody assay.
abstract: The suitability of collecting whole blood specimens on filter paper disks for HIV antibody assay was evaluated. ELISA and Western blot assay results were in complete agreement for serum and blood spot disk samples. Sensitivity of the two methods was tested using diluted whole blood and sera from HIV-seropositive individuals. Results demonstrate that ELISA and Western blot assays performed on punched-out disks of the blood-impregnated papers had the same sensitivities as those obtained with serum samples. This study suggests that whole blood collection on filter paper can be effectively substituted for serum sampling in HIV antibody screening programs.
