Can HIV be detected through a complete blood count test?

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

Patient's Query

Hello doctor,

Will a complete blood count test show HIV (Human Immunodeficiency Virus) infection? Will the WBC (White Blood Cells) be increased or decreased?

kindly guide.

Hi,

Welcome to icliniq.com.

WBC (white blood cells) increase or decrease in the complete blood count can tell about the presence of infection, whether viral or bacterial, but it cannot specify which organism is causing it. In other words, an increase or decrease in the counts can occur in numerous conditions, but which particular condition is there cannot be specified. To diagnose HIV (human immunodeficiency virus), one needs to be tested by serology, which can be done by a rapid or ELISA (enzyme-linked immunosorbent assay) test. Hope your query is answered, but if you have any other questions, please do not hesitate to ask or call anytime.

Thank you.

Patient's Query

Hi doctor,

Thank you for replying. My WBC has always increased and decreased, but I have never cared about it. I got an HIV test also, which was negative. So, I need not be worried, right? Is an increase or decrease in WBC an indication of a disease, even if the HIV test is negative? Are these HIV tests reliable?

Hi,

Welcome back to icliniq.com.

You have not provided any information about the exposure. The test might require repetition, but the details provided by you were incomplete. Please get back with complete information, and you can also attach your reports for interpretation.

I hope this helps.

Thank you.

Patient's Query

Hello doctor,

Thank you for the reply. Last year, I had a client in my office who was HIV positive. I was scared that I might have got infected by him, through drinking water contaminated by him. Or I feel that if a little of his blood got into the water that I drank. So, I got an HIV third-generation test after three months, which was negative. And after five months, I got an HIV fourth-generation test, which was also negative. Then a doctor suggested that there is no need to get another HIV test done if there was no sexual exposure. Do I need to be scared? Do I have to get tested again? So far, I have done four HIV tests, which were all negative.

Hi,

Welcome back to icliniq.com.

With these details, you do not require any HIV testing. Just relax.

I hope this helps.

Please feel free to reach out in case of further queries.

Thank you.
