ABSTRACT

Se estudia la posibilidad de detectar anticuerpos al VIH-1 mediante un estuche de Immunoblotting, en un papel de 125 muestras conocidas de sangre seca colectadas en papel de filtro y su correspondiente muestra de suero. No se apreciaron diferencias en los patrones de bandas con ambos tipos de muestras, así como en la sensibilidad y especificidad, donde se alcanzaron cifras del 100 %, lo que permitió concluir que la muestra de sangre tomada en papel de filtro puede ser empleada para la detección de anticuerpos al VIH-1 por el sistema DAVIH-BLOT y puede ser conservada a 4 ºC por 30 semanas.


The possibility of detecting HIV-1 antibodies by an inmunoblotting kit is studied in a panel of 125 known specimens of dried blood spotted on filter paper and their corresponding serum samples. No differences were observed in the patterns of bands with both types of samples or in the sensitivity and specificity, where 100 % figures were attained, allowing to conclude that the blood specimen taken on filter paper may be used for the detection of HIV-1 antibodies by the DAVIH-BLOT system and may be kept at 4 ºC during 30 weeks.
