Does negative index value in HIV tests indicate pre-existing immunodeficiency?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I had an unprotected sex, and then after 18 days, 40 days, 90 days, I had an HIV (Human Immunodeficiency Virus)1 and 2 antibody test including p24 (combo test). All four times it was negative index value around the same of .016. I have read about immunodeficiency people developing late antibody.

I am really stressed out that am I having pre-existing immunodeficiency. I have never been hospitalized for any medical reason, and I do not fall sick very soon, like I get fever once in two years.

Please advise what to do. Should I test again?

Thank you.

Hello,

Welcome to icliniq.com.

If you go again and get tested and then also if it is below 1.0, you are not at all infected with HIV. As per your statement, you had no complaints till test. If you felt sick, then it might be a problem.

For any sickness due to low immunity, do not have any assumption or prediction as it is not fine. So do not go for any test. Try to boost up your immunity with a healthy diet, morning walk, some outdoor activity.

I hope it helps.

Thank you.
