Should I worry if I had a fever after a negative HIV test?

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

Patient's Query

Hello doctor,

I have been having unprotected sex, and I got gonorrhea, but it has already been treated. About six weeks ago, I started experiencing a recurring fever, which is still continuing.

Fatigue is also there, and I have also been experiencing a sore throat for almost a week, mouth ulcers, and diarrhea for almost a month. There is also some phlegm in my throat. I have also been having a headache until now.

I got tested about nine days ago, and it was negative. I am very depressed because I am still experiencing fever and body pain until now.

I got my CBC and urine tests done, and they were all normal. I wanted to go to the doctor, but I think it would be a waste of money because it feels like these symptoms are because of HIV

  • Is it a good sign to have a negative fourth-generation test?

  • Do you think these symptoms are because of HIV or something else?

They told me it was just because I was very stressed, which is why the fever and headache came on. I would be very grateful to hear your advice.

Kindly help.

Hello,

Welcome to icliniq.com.

I read your query and understood your concern.

A CMIA (chemiluminescent microparticle immunoassay) is a fourth-generation ELISA (enzyme-linked immunosorbent assay), also known as a combo assay. This advancement over earlier generations has significantly improved our ability to detect hiv infection earlier than was previously possible.

It has the capability to detect both HIV (human immunodeficiency virus) antibodies and p24 (a protein found in HIV) antigen simultaneously due to the coating of microtiter plates with both antigen and antibody for hiv at the same time. This dual detection ability is what makes it particularly reliable and efficient in clinical practice.

The p24 antigen is detected first. Antibodies develop in response to the antigen. So when there is no antigen, there is no formation of antibodies. This sequence is important to understand because it directly explains why the timing of the test matters so much in determining its accuracy.

Three months is said to be the window period. This means a test done before this period is complete may not give a conclusive result, even if infection has occurred, and repeat testing may be necessary to arrive at a definitive answer.

I would advise you to visit a physician. Clinical examination is very important. No test result should ever be interpreted in isolation. A thorough clinical evaluation by a qualified physician ensures the result is understood in the right context and that appropriate guidance and next steps are provided without delay.

I hope you are satisfied with my answer. For further queries, you can consult me at iCliniq.

Thank you.
