ELISA versus EIA

Is there a difference between an ELISA test versus EIA? I recently had bio-rad HIV 1/o/2 gs plus OEIA. Didn't know if there was a difference. And by the way, it was 22 week negative.

it could be, all depending on the results of
the initial screening..
the ELISA is a two tiered screening process
they will use either enzyme immunoassay ("EIA")or immunochromatographic card assay...
if they get a positive hit
then they do western blot follow up
if a neg hit then they don't do the western.

so if they used the enzyme immunoassay ("EIA")
and got a neg hit then it would be the exaxt same as the ELISA
if they used the immunochromatographic card assay...
then its obviously different
and if they get a positive hit then the added western would
make it different
i hope this explains it
