Welcome to e health forum.
The complete hemogram or the total WBC count is not the best way to check for the HIV status.
The WBC count can remain elevated, even after years of HIV infection. It is severely low only in late stages of HIV, when AIDS (acquired immunodeficiency syndrome) is developed.
Your WBC counts appear to be normal at the present.
In case you want to check your HIV Status, you should do a HIV 4TH Generation ELISA test, which will be the conclusive test with regard to HIV diagnosis.
I hope this helps.
