Brief Answer:
Symptoms are unlikely to be due to HIV infection
Detailed Answer:
Hi,
Welcome to ASK A DOCTOR.
Thanks for posting your query.
First of all, your exposure was a protected one.
Earliest symptoms in the presence of an HIV infection (Acute infection) can occur only after 3-4 weeks and not earlier.
A non-reactive 4th generation HIV combo test especially after the completion of 4 weeks after the exposure ruled out HIV 1 infection (antigen part of the test). Antibody detection will be considered more conclusive 12 weeks after the exposure. HIV 1 infection is more common throughout the world except certain pockets of XXXXXXX to extent of 99%.
Regarding the RNA PCR the qualitative test is diagnostic and not the quantitative...that too considered more conclusive 3-4 weeks after the exposure.
Consult a physician nearby and get treated for your present symptoms.
Your problem does not seem to be related to HIV infection.
You can repeat the test 12 weeks after the exposure and rule out HIV 2 also.

Brief Answer:
HIV 2 detection is available with separate PCR test
Detailed Answer:
Hi,
Welcome back.
HIV 4th generation test has two parts. Detection of P24 antigen of HIV 1, and detection of antibodies against HIV 1&2. Antigen detection is possible as early as 1 week whereas the detection of antibodies against HIV 1&2 is possible only after the window period which may be delayed up to 12 weeks after the exposure.
HIV 2 detection can be done with any of the antibody tests after the window period.
HIV 2 antigen PCR test is available with very few laboratory on request.
