A 18 y/o male presents with yellow skin and clay colored stool. If the diagnosis if Hepatitis A infection, which of the following is needed to make the diagnosis with ELISA?

1) Goat anti-IgG
2) Surface protein of HAV
3) Goat anti-IgM

I always have troubles in ELISA questions :(


the Q is very short and non specific

which of the following is needed to make a dx with elisa from where? the pt serum? or to complete the kit of elisa?
