Brief Answer:
HSV 2 IgG ELISA would be conclusive at 12-14 weeks

Detailed Answer:
Hello. Thank you for writing to us

I have gone through your query and I have understood your concern.

In the absence of any history of clinical lesions of herpes I think your chances of having herpes at 9-10 weeks of possible exposure is very low, however, I suggest you to test again with HSV 2 IgG ELISA at 12-14 weeks to make sure you are still negative. At 12-14 weeks it would be a conclusive test.

Brief Answer:
Another HSV type 2 IgG ELISA would be conclusive

Detailed Answer:
Hi.

Yes, HSV 2 can stay asymptomatic for long periods of time and many infected individuals are not even aware of the infection. Since its been already 6 months from exposure so you can take another HSV type 2 IgG ELISA and that would be conclusive.

Brief Answer:
fordyce spot

Detailed Answer:
Hi.

Your latest test report is fine and it states that you are conlusively negative.
The image of your penis shows that you have a fordyce spot on penis. A fordyce spot is nothing but an ectopic sebaceous gland. It is a normal finding in many.
