Hello,

Quest uses EIA on neuropathy antibody testing, while Athena uses ELISA.

On some Neuro. Antibody tests, it says Athena does both , ELISA and WESTERN BLOT (re-confirming). Does it mean the ELISA has to be positive for the WESTERN BLOT to be run, or are these 2 methods run at the same time and then compare results?

It does not say that Quest runs more than EIA on most tests, do they run western blot also if EIA is positive?

ELISA or EIA better, no difference?

Any insight anyone?
