Thank you for your inquiry. From what we gather from the question, you were asking about the negative results and index values of the HIV tests you accessed after a possible HIV exposure.
An increasing index value on an HIV test does not indicate that you have HIV, rather, it reflects the variability of laboratory tests. If the index value of your chemiluminescent microparticle immunoassay (CMIA) HIV test was hovering closer to 1, the laboratory would contact you requesting a follow-up blood specimen. Since your index values are all greatly below 1, you can be rest assured that the negative results you received outside of the 3 month window period are completely conclusive.
Recommendation: No further testing is required since HIV testing with a negative result has been accessed outside of the window period. Refer to a healthcare professional for other health related questions.
