My HIV tests are negative 145 days after exposure. Do I need any more tests?

Hello doctor,

My query is regarding HIV (Human Immunodeficiency Virus) and AIDS (Acquired Immunodeficiency Syndrome). I had unsafe sex with a girl. After 40 days of exposure, I did anti-HIV CMIA (Center for Medical Imaging and Visualization) test which was non-reactive and the value was 0.24 (non-reactive). Then, after 145 days of exposure, I did HIV 1 and 2 screening test which was also non-reactive having result 0.17 (non-reactive). Now, it is almost 250 days of my exposure. I feel my body is becoming thin. I am worried about HIV because I am losing weight which is a symptom of HIV. Do I need more tests? Is there a chance of HIV laterals I did the test after 145 days of exposure and it was non-reactive. No other symptom is present in my body. Only that I lost 6.6 to 8.8 lbs weight after the exposure. And, also tell what is the accuracy level of the above tests I had.

Thank you doctor,

What about the accuracy of the above tests? Please tell me if these tests are sufficient to make sure that I am HIV negative.
