Question: I had one HIV test which showed a reaction, a follow up test came back negative and subsequent blood tests have shown a 'very faint' reaction still waiting for antibodies results - is there any chance I could be HIV positive

Hello,

Thank you for posting a query.

Look, generally, ELISA tests are done to detect HIV infection. But this reaction easily may give false positive result in many conditions. The list is very long. Basically, presence of cross reacting antigens in blood reacts with the reagent to give this type of confusing results.

So, this reaction has to be differentiated from a true positive result. For that, detection of specific antibody is very important. But, PCR test specific for Human Immuno Deficiency Virus (HIV) should also be considered.

So, there are some chances that you could be HIV positive. But it should be investigated meticulously as I told you to diagnose you as a HIV positive. Without these tests done, no one can say that you are HIV positive.

Lastly, consult with your treating doctor about the test PCR test and wait for the antibody report.

Hope this information suffices. Let me know, if you have any more questions.

Regards.

Dear Doctor, My name is Mohamed, I had unprotected anal sex with a women whom I didn’t knew her status on the 24th January 2014. On the 26th January I visited Hospital and was tested Elisa and P24 and all was Negative and I was advised to take PEP……. But I stop the PEP only after taking days ( 1 tab each day ) due to the side effect. I tried to test the lady but she assured me that she was 100% clean. Three weeks later I tested for P24 and was NEGATIVE, I started having general weakness, loss of appetite, fever and neck and groins pain and I again visited Hospital and Malaria was found in my blood and put on injections and tabs….. The fever and the pains has slightly went down. Six weeks post exposure I visited HIV specialist and he did physical assessment on my mouth and body – before sending for test he told me that I don’t have HIV, I tested PCR and HIV Proviral, DOU test and ELISA DNA from two major reliable labs ( Nairobi Hospital, MEDANTA and Metropolis ) and all come back NEGATIVE. I also did general Blood Picture which was normal as my Dr told me. The doctor told me that I have psychological problem and he sent to phsycatricst who gave me depression tabs… I now feel better but sometimes mild fever and pain on the neck lymph nodes and groins. So I am still worried and don’t know what will happen as all the doctors told me no need to do another test and completely forget about it. Please advice me? Thanks, Mohamed
