VIRUS INSIDE BODY TRIGGER OUR IMMUNE SYSTEM TO PRODUCE FIGHTING BODIES CALLED ANTIBODIES WHICH ARE DETECTED BY TRIDOT TEST SOME TIME VIRUS PRODUCE THESE ANTIBODIES VERY SLOWLY AND MAY TAKE 06 MONTHS SO MAY NOT BE DETECTED BY A TRIDOT TEST WHICH ONLY DETECT VIRUS BY LOCATING ANTIBODIES BUT BY PCR WE CAN DETECT VIRUS TOO IN VERY LESS AMOUTN I.E., WIHIN 2 WKS OR LESS AFTER EXPOSURE.

Hi welcome to Healthcaremagic

Hi kush..., the virus in the body takes time to multiply, and also the body takes tine to react against the virus to produce anti bodies against it.., hence during test after sexual exposure , the test can come as negative and become positive after few months,, but maximal upto 6 months, after that virus cant be silent int he body , with out triggering the immune system some times the virus in the hence doctors advice est to be done after 6 months to rule out maximal incubation period of the virus
Hope I have answered your question..

Takecare...
