MIRANDA-ULLOA, Eduardo et al. Evaluation of three serological tests for the detection of antibodies against human T-lymphotropic virus type 1 (HTLV-1). Rev. Cuerpo Med. HNAAA [online]. 2023, vol.16, n.1, pp.83-87. Epub 27-Mar-2023. ISSN 2225-5109. http://dx.doi.org/10.35434/rcmhnaaa.2023.161.1516.
Background:
Peru is endemic to the human T-lymphotropic virus type 1 (HTLV-1), for these reasons it is important to know the reliability of the diagnostic tests used in the country, in order to continue their use or not.
The objective
was to evaluate the performance of three serological tests ELISA Murex, ELISA Wantai and IFI INS-Peru for the detection of anti-HTLV-1 antibodies against Peruvian samples.
The study.
The three tests were evaluated against 382 sera: 215 positive and 167 negative for HTLV-1 (Gold Standard: immunoblot).
Findings.
IFI had no false positives, Wantai had more false negatives (seven) and Murex more false positives (eight). The three tests showed results above 95% for the estimated parameters of diagnostic accuracy.
Conclusions.
IIF INS-Perú and ELISA Murex had good diagnostic performance for the detection of antibodies against HTLV-1 and are good candidates to continue being used in Peru.
Palavras-chave : HTLV-1; ELISA; Fluorescent antibody technique indirect.
