The clearest answer in HIV confirmation testing: INNO-LIA® HIV I/II Score

When you are confronted with repeatedly reactive HIV screening patient test results it is strongly recommended1,2,3,4 that you confirm these results with other reliable techniques, such as the INNO-LIA™ HIV I/II Score immunoblot assay.

The INNO-LIA HIV I/II Score test contains recombinant proteins and synthetic peptides from HIV-1 and HIV-2 as well as a synthetic peptide from HIV-1 group O. These carefully selected antigens are coated at optimal concentrations as discrete lines on a nylon strip with plastic backing.

This immunoblot test detects seroconversion earlier than other confirmation technologies and gives less indeterminate results5-6. This reduces the need for repeated testing and thus limiting extra costs.

Compared to other testing technologies the INNO-LIA HIV I/II Score assay provides clear differentiation of HIV-1 and HIV-2 infections6-7-8 - which allows for much more adequate patient treatment.


So, here are some of the key advantages of using our gold standard immunoblot assay for HIV confirmation testing:

  • It’s the latest generation of a reference test with more than 25 years of accumulated and widely documented HIV testing results across the world.
  • It reliably confirms and differentiates HIV-1, HIV-1 group O, and HIV-2.
  • It gives a low number of indeterminate results.
  • It comes with ready-to-use and color coded reagents.
  • It offers clear cut, standardized and objective reading and interpretation of results.
  • It features flexible strip processing with both short and overnight procedures plus efficient walk-away automation; read the results when you are ready.
