I have taken 23 HIV test due to white coating on my tongue.
Every test has been negative over 10 month period of time. Please advise if antidodies can take greater 10 months to appear.
Twenty-three negative HIV tests (23!!!?!) over a 10-month period? WOWZA! Dude, exactly what part of "HIV negative" are you having difficulty understanding? Your tests are definitive, conclusive, WOO-HOO-able and highly excessive. HIV is not your problem. No way. No how. No additional HIV testing is warranted. You've had way too many already.
Regarding your specific question, what the heck are "antidodies"??? As for anti-HIV antibodies, no, they do not take longer than 10 months to develop.
