Hie doctor. What is the hiv window period in india? Because one of your Lybrate verified doctor Dr. ajay pal singh claimed that I have seen many cases where hiv not picked upto 4 years, 5 years and 6 years. If he's right what are the reason behind this? I queried everywhere whether cdc or who and even ictc naco all said that 3 months is maximum window period and when people have certain disease it could be maximum 6 months. If Mr. ajay pal singh is wrong how inefficient and roadside quack are claimed to be doctor in well known application Lybrate. Please clarify me sir. I shall be highly obliged for your kindness.
