need to test again ??

Guys..you helped me to get rid of anxiety one year back after a potential exposure.
I went for ELFA test after 3 and 6 months.Both came negative.But now exactly after 1 year, I got sore throat and ulcers on my
mouth.Could you please let me know
1.what ELFA means ??
2.How reliable it is ??
3.Do I need to test again ?? - or it can be because of some other reasons -

Your test was 100% conclusive after 3 months, further testing is not needed

Hope this helps

Could you please answer first 2 questions ?
And what is the difference with ELISA ?

[NickOne7]

The Enzyme-Linked Fluourescent Assay (ELFA) is a slightly newer version of the Enzyme-Linked Immunosorbent Assay (ELISA) test. Both work in a similar way but the ELFA has a window period which is about 5 days shorter than the ELISA test. Both are very accurate. This means your results are conclusive. You do not have HIV.
