Evaluación de los equipos comerciales utilizados en los bancos de sangre de Córdoba para la detección de anticuerpos anti HTLV-I/II / Evaluation of commercial equipment used in blood banks in Córdoba for the detection of anti-HTLV-I/II antibodies

RESUMO

In order to assess the efficiency of currently used screening tests, Abbott HTLV-I/HTLV-II EIA, Vironostika HTLV-I/II Organon Teknika, Particle Agglutination (PA) assay Serodia Fujirebio Inc. (Tokyo, Japan) for HTLV-I/II antibody detection in blood donors samples, a panel of 100 sera from different blood banks of Córdoba city were studied. An "in house" indirect immunofluorescence assay (IFA) was used as reference test. The correlation rates were 66 for Abbott HTLV-I/HTLV-II EIA, 97 for Vironostika HTLV-I/II Organon Teknika EIA and 99 for PA Serodia. Vironostika HTLV-I/II Organon Teknika EIA and PA Serodia assay proved to be more reliable for HTlV-I/II antibody screening in blood donors from Córdoba, yielding a very low rate of false positive results as compared with Abbot HTLV-I/HTLV-II EIA.
