What is the difference between ELISA test and elfa test for HIV testing. I had a risky adventure and tested negative for HIV 1 and 2 as per elfa test?

In brief: Shorter detection

Elfa is the new version of the elisa test; it has about a 5 day shorter detection time, being 95% sensitive at 28 days.

I learn something every day that I am here, Dr. Ho. Where is the ELFA in use?
