Yes a rapid test is an ELISA test.
Great answer and thank you both!!!!!
Looks like you got lot of misinformation together. Firstly, the window period is 3 months and not 6. Secondly, you need a test at the 3rd month with an antibody test. Could be ELISA, CMIA, ELFA etc. As long as it is an antibody test it works. ELISA is just the technology of the test used to detect antibody. However, it's the most conventional technology and widely used. Thirdly, oraquick is an antibody test and uses the ELISA technology.
your test was RELIABLE and CONCLUSIVE :)
