Hello After 10 weeks she tested for HIV infection , rapid finger prick test and report is NEGATIVE . Antibodies to HIV begin to appear within 2 weeks of infection ( in your girl case it is 10 weeks ) and the period of time between initial infection and the development of detectable antibodies is rarely more than 3 months . This test is highly sensitive ( 99.5% ) and is quite specific. Since you are STD free and girl is also HIV free , so in my opinion this is not a cause of concern . Don t worry , you are HIV free according to this query. Good luck.
