Serology reagents used to corroborate (i.e., confirm) the results of a previous test for the presence of antibodies to human T-cell lymphotropic virus (also called human T-cell leukemia/lymphoma virus) type I (HTLV-I). HTLV-1 retrovirus is a tumor-producing RNA virus of the subfamily oncavirinae; it may cause chronic infection, T-cell leukemai, and tropical paraparesis (chronic progressive myelopathy). Confirmatory assays frequently use a different approach or a more specific methodology than the original test; they typically cost more and/or require more sophisticated devices or greater skills.
