Can the results of a Herpes exam come out erroneous?

Did an Igm Herpes exam and my results were HSV 1 IGM 1:20A Positive A and HSV 2 IGM 1:40A Positive A.

I have not had a genital herpes outbreak, but I have had a cold sore in two occasions in my mouth. Could there be a chance that the results for genital herpes are picking up on the antibodies for oral Herpes?

Is there a more specific test I could do to make sure that I have genital herpes?

How easy is it to transmit herpes to a sexual partner? Would they get infected with both types of Herpes if having unprotected sex?

Does this mean I shouldn’t give oral sex?

the IGG is more specific
