Brief Answer:
interpretation depends on test done

Detailed Answer:
Hi, thanks for using healthcare magic

Yes, you are likely negative, but whether it is conclusive would depend on the test done.

There are different types of HIV tests. The most commonly used screening test, the elisa test, has a window period of 3 months. This means that it can take up to 3 months in some persons before the test can give a definite result.

The window period of a tests is the time after possible infection, before the body makes the chemicals that are detectable by tests.

If you did the most common ELISA test, then you may want to repeat in 2 weeks (when you would have passed the 3 month mark), to repeat it. At this time it would have passed the window period for this test.

HIV PCR testing however has a shorter window period of 2 to 3 weeks because it looks for the virus itself not the body's reaction to it like the ELISA test.

If your test was an HIV PCR test then it is definitely conclusive and you do have HIV.
The HIV RNA testing also has a short window period of 1 to 3 weeks.

Summary- interpretation would depend on test done. If Pcr DNA or HIV RNA then you are negative.
If an ELISA test was done , you may want to consider repeating in 2 weeks

I hope this helps, feel free to ask any other questions

Brief Answer:
this is an antibody test

Detailed Answer:
Hi

This is an accurate test. It relies on detecting antibodies (formed if the body reacts to the presence of HIV).
Because it detects these antibodies, the window period is 4 weeks up to 12 weeks.

This means for a truly conclusive result, you may want to repeat this in 2 weeks or have either a pcr dna or an rna done at this point.
