What test should I have?

RT-PCR saliva test if you want to know if you have Covid-19 currently because you have symptoms or were recently exposed to a known a person with Covid-19.

IgM/IgG antibody test if you want to know if you have already had Covid-19 in the past and have possible protection or were sick 2 to 3 weeks ago and want to know if safe to return to work or school.
