Brief Answer:
No, Doxycycline won't cause

Detailed Answer:
Welcome to Healthcaremagic.
Hi, I am Dr Anshul Varshney , I have read your query in detail , I understand your concern.
No, Doxycycline won't cause a false positive HSV 2 test. You are probably suffering from that and hence, the infection is there. So, i would recommend in such case to go for IgM or IgG evaluation to know that the infection is recent or an old one.
HSV 2 commonly causes genital herpes and spreads through sexual contact and skin-to-skin contact.
This is my personal opinion based on details available here. If you still have any other query, you may please ask me.
Stay Healthy.

I was tested on Monday and have never had any signs. Does Doxycycline impact results?

Brief Answer:
No effect

Detailed Answer:
Doxycycline doesn't interfere with the results of HSV as these are antibody tests, and your body must be carrying antibodies against HSV leading to positive results. So, Doxycycline neither interferes with the test performed, not gives the false positive result.
Good Luck.
