A rapid antigen/antibody test done with blood from a finger stick can usually detect HIV 18 to 90 days after exposure

Take a Hepatitis B Virus - Viral Load Test Test or Take a Echinococcus Antibody, IgG (Hydatid Serology) Test

After 10 weeks (70 days) of unprotected sex with a sex worker, I took a 4th generation HIV assay test at SRL Lab, and the result was non reactive. How safe am I from HIV after 90 days? Is there any chance that the HIV test could become positive after 90 days? Can the SRL Lab report at 70 days be considered reliable? I have attached the report for reference.

After potential HIV exposure, I have done multiple HIV tests over 9 months, and all results were negative. My reports for the past three months are as follows 0.2 s/co, 0.2 s/co, and Antibody + p24 antigen test by ECL method is 0.2 s/co. Do I need to undergo any further HIV testing, or are these results conclusive?

Hello Doctor, I recently did an HIV test using the ICT method about 1 month after possible exposure. How accurate is this test at this stage? Should I get tested again for confirmation?
