Table 1 Western blot results in the eleven serum samples with different level of reactivity by immnoenzymatic assay (ELISA).

From: Human T-lymphotropic virus type 1 (HTLV-1) prevalence and quantitative detection of DNA proviral load in individuals with indeterminate/positive serological results

  1. WB positive: serum reactivity to envelope and gag proteins.
  2. WB indeterminate: serum reactivity to one or two HTLV-1 proteins.
  3. WB negative: lack of reactivity to viral proteins.
  4. ELISA borderline: absorbance value equal to or greater (ranging from 0.1 to 0.5 optical density) than the cut-off value
  5. ELISA positive: absorbance value greater (ranging from 0.6 to >2.00 optical density) than the cut-off value
