User :   but on 4th month before i went to elisa test i mean the day before i took elisa test i got common cold
Doctor :   ok

User :   and now its 5th month from encounter and i am getting whoping cough,sore throat and also two mouth ulcers which is red
Doctor :   ok

User :   whats my chances of having hiv?? or u think i dont have since i tested negative at 4th month on elisa??
Doctor :   i do not want to guess the chances as guess will not work out

if DNA PCR is negative it means you are not having the infection

User :   ok fine
User :   but i really didnt get technical help from u regarding my problem instead it was just like showing me the road map for these hospitals and testing center
Doctor :   like
Doctor :  
what technical help you want?
User :   u didnt tell me anything abt my problem like u suspect that i may be infected or chances are less or absolutely nothing i have
Doctor :   yes you have the risky behavior of having the unprotected sex
Doctor :  
and whether you have been infected or not that will be diagnosed by the test
Doctor :   there is some thing called window period
Doctor :  
in which your elisa and tridot will be negative
User :   doctor i accept that i made this mistake but believe me this was my first and i have decided that its last too but what i need to know is the answer from u like "chance"
User :   see what ur saying i have read everything on net
Doctor :   yes
User :   window period
Doctor :  
it is there on net
User :   and acute hiv symptoms etc etc
User :   but tell me
User :   in these 5 months i had no fever and no lose motion (diearea)
User :   no headache
User :   only common cold which lasted for 5 days
User :   at the 4th months
User :   i got tested after i got common cold after 4th month but elisa test came as negative
Doctor :   the latent period for somebody to manifest the symptoms vary from 6 months to 5 years
Doctor :  
from the time of infectivity
Doctor :  
any ways the multiple tests being negative do say the chances are very low that you are infected
Doctor :   it does not rule out completely

User :   then u mean elisa test after 6 months only is confirmative?
Doctor :   i said confirmative test is DNA PCR
User :   my family doctor said elisa test at 4th month negative means 99% not infected
Doctor :   but what about 1%
User :   yes thats there
Doctor :   now got it what i mean
User :   does whooping cough signal acute hiv symptoms?
Doctor :   whooping cough will not affect adults
Doctor :  
if you want to be 100% sure than it is DNA PCR
Doctor :  
Doctor :  
if it is negative than you are 100% negative
User :   but on net doctors say it may give even wrong signals bcoz of someother anti body presence
Doctor :   DNA PCR detects antigens not antibodies
User :   how many % of people experience only sore throat in acute hiv stage?
User :   how many % of people experience only sore throat in acute hiv stage?
